Flight Attendant Duty Period Limitations and Rest Requirements

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This final rule sets forth regulations that require air 
carriers, air taxi, and commercial operators to provide duty period 
scheduling limitations and rest requirements for flight attendants 
engaged in air transportation and air commerce. This action results 
from public and congressional interest in regulating flight attendant 
work hours and from data contained in a Federal Aviation Administration 
(FAA) study of industry practice relating to flight attendant flight, 
duty, and rest times. This rule contributes to an improved aviation 
safety system by providing the opportunity for flight attendants to be 
rested sufficiently to perform their routine and emergency safety 
duties.

EFFECTIVE DATE: This regulation is effective September 19, 1994, except 
Secs. 121.683(a)(1), 135.63(a)(3), 135.63(a)(4)(x), 135.63(a)(5), and 
135.63(b) which are not effective until the Office of Management and 
Budget (OMB) has approved the Paperwork Reduction Requirements. FAA 
will publish a document in the Federal Register following OMB approval 
of the Paperwork Reduction Requirements.

COMPLIANCE DATE: March 1, 1995.

Background

Statement of the Problem

    Flight attendants are crewmembers who perform essential routine and 
emergency safety duties. Routine duties include ensuring that carry-on 
baggage is correctly stowed; verifying that exit seating requirements 
are met, that passenger seat belts are fastened, and that galley 
service times are properly stowed; and conducting passenger briefings 
before takeoff. Emergency duties include conducting land and water 
evacuations, controlling inflight fires, handling passengers who 
threaten the safety of other passengers or the flight, managing medical 
emergencies such as passenger illness or injury, managing inflight 
emergencies such as smoke or fire in the cabin, and managing turbulent 
air penetrations, airplane decompression, and hijackings. Additionally, 
because flight attendants are crewmembers performing safety-related 
functions, they must satisfactorily complete indoctrination, initial, 
transition, and recurrent training requirements. In addition, they are 
subject to the alcohol and drug use regulations and drug testing 
regulations. Currently, flight attendants are the only safety-sensitive 
aviation group that has no regulations with respect to flight, duty, or 
rest periods. Such regulations exist for flight crewmembers, 
dispatchers, air traffic control tower operators, and aviation 
maintenance technicians.
    This final rule is comparable to flight, duty, and rest 
requirements for other safety-sensitive aviation groups because it 
enhances public safety by requiring ``rest periods'' and limiting duty 
periods for flight attendants. These requirements protect flight 
attendants from work related fatigue that interferes with their ability 
to perform essential safety duties. No accident/incident data currently 
exists to provide a direct correlation between flight attendant fatigue 
and passenger survivability. However, the FAA recognizes that a flight 
attendant who is excessively fatigued is less likely to be capable of 
performing safety duties than an adequately rested flight attendant. 
This is an unacceptable safety risk. Therefore, the FAA adopts this 
final rule in the interest of air transportation and air commerce 
safety. The justification stated herein includes that which was 
included in Notice of Proposed Rulemaking No. 93-3, published in the 
Federal Register on March 31, 1993 (58 FR 17024).

Historical Review

    In 1985, the FAA received two petitions for rulemaking requesting 
limits on flight and duty hours for flight attendants. One petition\1\ 
sought to establish flight and duty time regulations similar to current 
regulations for flight crewmembers. The other petition\2\ recommended 
establishing maximum duty time limits and minimum daily, weekly, and 
monthly rest periods. Both petitions recommended certain flight time 
limitations and rest requirements for flight attendants that were more 
restrictive than those that existed for flight crewmembers. The FAA 
denied both petitions in a Denial of Petition issued on January 23, 
1989, because the action sought by the petitioners was not warranted by 
the information, views, and arguments contained in the petitions.
---------------------------------------------------------------------------

    \1\This petition was submitted by the Association of Flight 
Attendants and summarized in the Federal Register (50 FR 6185) on 
February 14, 1985.
    \2\This petition was submitted by the Joint Council of Flight 
Attendant Unions and summarized in the Federal Register (50 FR 
25252) on June 18, 1985.
---------------------------------------------------------------------------

    Congressional legislation (H.R. 638 and S. 1170) was introduced in 
1989 to establish flight attendant duty time limitations. On May 17, 
1989, the Subcommittee on Aviation of the House Committee on Public 
Works and Transportation held a public hearing on H.R. 638. At the 
hearing, the FAA stated its intent to initiate further studies of air 
carrier flight attendant scheduling practices.
    The FAA completed its ``Report on the Study of Current Industry 
Practice-Flight Attendant Flight, Duty, and Rest Times'' on September 
12, 1989 (hereafter referred to as ``the Industry Study'' [Docket No. 
27229]), and submitted a copy of the study to the House Subcommittee on 
Aviation. The study focused on U.S. air carrier scheduling practices 
and flight attendant actual work hours and highlighted cases of 
extended duty periods and minimum rest periods. The study indicated 
that flight attendant duty hour problems may occur more frequently 
among certain industry segments because of fundamental operational 
differences. The study noted that most air carriers had policies to 
address these problems. The study provided a framework for the FAA to 
address this issue with appropriate regulatory action, which is 
provided in this final rule.
    The House Subcommittee on Aviation held another hearing on flight 
attendant duty and rest on March 13, 1991. The FAA did not recommend 
rulemaking at that hearing. Subsequent legislation on flight attendant 
duty and rest, H.R. 14, was passed in the House of Representatives. In 
1992, the language of H.R. 14 was incorporated into a provision in the 
House and Senate versions of the FAA's appropriations bill; however, 
that provision was deleted later by the conference committee. On 
January 5, 1993, H.R. 14 was reintroduced in the House of 
Representatives.
    On March 26, 1993, the FAA issued a notice of proposed rulemaking 
(NPRM), Notice No. 93-3, Flight Attendant Duty Period Limitations and 
Rest Requirements (58 FR 17024; March 31, 1993) that proposed duty 
period scheduling limitations and rest requirements for flight 
attendants engaged in air transportation and air commerce. The FAA has 
incorporated into this final rule comments on the NPRM received from 
the public during the comment period, as appropriate.

Discussion of Comments

    Fifty-one commenters submitted comments in response to the NPRM. 
The commenters included trade and professional associations, individual 
flight attendants, labor organizations, part 121 and 135 operators, 
public interest groups, a government agency, a Member of Congress, and 
other individuals. Among the commenters were the Air Line Pilots 
Association (ALPA); the Air Transport Association (ATA); the Allied 
Pilots Association (APA); the American Cyanamid Company; AMR Combs; the 
Coalition of Flight Attendant Unions; Delta Airlines; Great American 
Airways; the National Air Carrier Association (NACA); the National 
Transportation Safety Board (NTSB); North American Airlines (NAA); the 
Regional Airline Association (RAA); Southwest Airlines (SWA); Sun 
Country Airlines (SCA); Transport Workers Union Local 556 (TWU Local 
556)--Southwest Airlines; and flight attendants, some of whom are 
employed by America West Airlines; Continental Airlines, Delta 
Airlines, and Sun Country Airlines.
    Commenters addressed general and specific issues such as scheduled 
versus unscheduled operations; the application of flight crewmember 
flight, duty, and rest requirements to flight attendants; rest period 
requirements; duty period requirements; augmented crew requirements; 
reserve and deadhead status for flight attendants; flight attendant 
responsibility; the costs contained in the initial regulatory 
evaluation; and the implementation period for this final rule. 
Commenters also addressed the issues of flight attendant fatigue, the 
Industry Study, international versus domestic operations, part 125 
operations, and flight attendant duty limitations and rest regulations 
in other nations.

Overview of the General Issues

    Thirty-nine comments addressed the concept of regulating flight 
attendant duty period limitations and minimum ``rest period'' 
requirements. Fourteen comments did not support establishing flight 
attendant duty period limitations and rest requirements while 18 
comments did support establishing such limits and requirements based on 
certain revisions to the proposed rule.
    The commenters who supported regulating flight attendant duty 
period limitations and rest requirements included ALPA, APA, The 
Coalition of Flight Attendant Unions, NTSB, nine commenters who 
identified themselves as flight attendants, and a member of Congress 
who strongly supports the comments of the Coalition of Flight Attendant 
Unions. The commenters stated that, because a flight attendant's 
primary duties are safety related, establishing regulations would 
enhance public safety.
    The 14 commenters who did not support the NPRM include Great 
American Airways, RAA, SCA, and nine commenters who identified 
themselves as flight attendants. Several of the commenters who 
identified themselves as flight attendants stated that the provisions 
in the NPRM would limit a flight attendant's opportunities to work 
extra trips and that flight attendants are capable of handling safety 
procedures and emergencies even when working longer duty periods.

Specific Issues

Apply Flight Crewmember Flight, Duty, and Rest Requirements to Flight 
Attendants
    In the NPRM, the FAA invited comments on the possibility of 
modifying the proposed rule, as presented in the NPRM, to add an option 
for operators to either follow the proposed duty limitations and rest 
requirements or apply flight crewmember flight, duty, and rest 
requirements to flight attendants.
    Eleven commenters responded to the FAA's request for comments. 
Seven of the commenters supported the option to permit operators to 
either follow the proposed duty limitations and rest requirements or 
apply flight crewmember requirements to flight attendants. Three 
commenters opposed the option. Although Delta Air Lines did not oppose 
the option, it expressed no interest in exercising the option.
    ATA, Great American Airways, NACA, RAA, and Southwest Airlines 
agreed that operators should be permitted to apply flight crewmember 
requirements to flight attendants. ATA specified that applying flight 
crewmember requirements should remain an option at the operator's 
discretion. Great American Airways, Horizon Air, NACA, RAA, and 
Southwest Airlines noted that there are scheduling and economic 
advantages to using the same set of rules of flight crewmembers and 
flight attendants.
    The Coalition of Flight Attendant Unions and SCA opposed 
establishing the option to permit operators to apply flight crewmember 
flight, duty, and rest requirements to flight attendants. The Coalition 
of Flight Attendants Unions stated that flight crewmember rules do not 
provide adequate protection from fatigue. SCA noted that, if this 
option had been a requirement in 1992, SCA would have had to hire an 
additional 20 flight attendants. According to SCA, the cost burden of 
hiring 20 flight attendants would have increased SCA domestic operating 
costs by $1.75 million.
FAA Response
    The FAA recognizes that giving operators the option to apply flight 
crewmember flight, duty, and rest requirements to flight attendants 
provides additional scheduling flexibility and eliminates the need for 
an operator to have two sets of scheduling requirements for its flight 
crewmembers and flight attendants. This provision also will permit 
flight attendants on such operations to be scheduled with the same 
limitations as the flight crewmembers. Therefore, the FAA has adopted 
this option, which appears in Secs. 121.467(c) and 135.273(c) of this 
final rule.
    If an operator chooses to apply flight crewmember flight, duty, and 
rest requirements to flight attendants, the operator must establish 
written procedures for applying the requirements and the procedures 
must be approved by the Administrator and referenced in the certificate 
holder's operations specifications. The written procedures must apply 
to all flight attendants used in the certificate holders operation. In 
addition, written procedures must be applied to the certificate 
holder's entire operation. Certificate holders may obtain approval by 
submitting their procedures for preliminary review and approval to the 
principal operations inspectors assigned to them at the FAA Flight 
Standards District Offices that are charged with the overall inspection 
of their operations. This approval process is similar to those used for 
exit seating and passenger carry-on baggage requirements. Because 
flight crewmember regulations were designed specifically for pilots, 
FAA approval is required to ensure that flight crewmember rules are 
adequately applied to flight attendants. In addition, the written 
procedures for domestic, flag, and supplemental air carriers and for 
commercial operators must apply the flight crewmember limitations 
contained in subparts Q, R, or S of part 121, except for the provisions 
for on-board rest facilities, as appropriate to the operation being 
conducted. Therefore, operators must consider the type of operation 
being conducted for each flight segment when scheduling flight 
attendants according to the option.
    In addition, the written procedures for establishing duty period 
limitations and rest requirements for operators certificated under part 
135 must include the limitations contained in subpart F, except for 
provisions for on-board rest facilities, as appropriate to the 
operation being conducted. Part 121 and 135 certificate holders are 
required to provide flight attendants on aircraft with certain 
passenger seating configurations in accordance with Secs. 121.391, 
135.107, or the certificate holder's operations specifications, as 
appropriate. The number of flight attendants required on an aircraft to 
meet the provisions of Secs. 121.391, 135.107, or the certificate 
holder's operations specifications, whichever is greater, is referred 
to as the minimum flight attendant crew complement.
    Any operator that elects the option to apply flight crewmember 
flight, duty, and rest requirements to flight attendants and has 
established written procedures for augmenting the minimum flight 
crewmember complement must establish procedures for augmenting the 
minimum flight attendant complement. The augmenting procedures must be 
based on the number of flight crewmembers assigned to the flight that 
is in addition to the minimum flight crewmember complement as specified 
in the aircraft type certificate data sheet. For example, if the 
minimum flight crewmember complement on a Boeing 747-300 is three, as 
specified in the aircraft type certificate data sheet, an operator that 
schedules four flight crewmembers for an extended long-range flight 
will be required to schedule one flight attendant in addition to the 
minimum flight attendant crew complement that is required by 
Secs. 121.391, 135.107, or the certificate holder's operations 
specifications. For example, if the operations specifications for a 
certain airplane requires 8 flight attendants, and if the operator adds 
1 flight crewmember, that operator would be required to add 1 
additional flight attendant, for a total of 9 flight attendants.
    In addition, any operator that elects the option of applying the 
flight crewmember flight, duty, and rest requirements to flight 
attendants, must ensure that the definition of ``rest period'' in this 
final rule is applied to those flight attendants. (See the detailed 
discussion on ``Rest Period Requirements'' and ``Reserve Status, Stand-
by Status, or Similar Assignments'' in this final rule.)
    Under the provision for applying flight crewmember flight, duty, 
and rest requirements to flight attendants, if the Administrator finds 
that revisions to the written procedures are necessary for the 
continued adequacy of the procedures for applying flight crewmember 
flight, duty, and rest requirements to flight attendants, the 
Administrator will require the operator to make necessary changes 
within 30 days after being notified by the Administrator. In addition, 
an operator may petition the Administrator to reconsider the notice to 
change the procedures.
    This procedure for requiring changes is consistent with the current 
regulatory language for aircraft inspection programs and pilot training 
programs contained in Secs. 91.415 and 121.405, respectively, as well 
as a number of other regulations.
    Any operator that establishes written procedures to apply the 
flight crewmember flight, duty, and rest requirements to flight 
attendants and that subsequently wishes to revise this practice and 
schedule flight attendants according to the duty period limitations and 
rest requirements in Secs. 121.467 or 135.273 must amend their 
operations specifications in accordance with Secs. 121.79(c) and 
135.17(b). These sections require a certificate holder to file an 
application for an amendment of operations specifications at least 15 
days before the effective date proposed by the applicant for the 
amendment, unless a shorter filing period is approved by the Flight 
Standards District Office charged with the overall inspection of the 
certificate holder.
Unscheduled Operations
    The NPRM proposed duty period limitations and rest requirements for 
flight attendants in all domestic, flag, supplemental, and commercial 
operations conducted under part 121 and part 125, and in all operations 
conducted under part 135. No new requirements for operations conducted 
under part 91 were proposed. The FAA received comments from part 121 
and 135 operators about the applicability of the proposed requirements 
to certain unscheduled operations. Those commenters included AMR Combs, 
ATA, American Cyanamid Company, Delta Airlines, Great American Airways, 
North American Airlines, and Southwest Airlines.
    ATA, Delta Airlines, North American Airlines, and Southwest 
Airlines said that the proposed duty period limitations and rest 
requirements should not apply to military flights, e.g., Civil Reserve 
Air Fleet (CRAF) and Military Airlift Command (MAC). ATA and Southwest 
Airlines also said that special charters for sports teams should be 
excluded from duty period limitations and rest requirements. Commenters 
stated that because of the short notification associated with military 
and special charters it would not be possible to obtain a waiver from 
the regulation to conduct them. North American Airlines stated that the 
proposed requirements should not apply to flights flown to remote 
destinations on a weekly or ad hoc basis.
    AMR Combs and American Cyanamid Company believe that the proposed 
requirements should not apply to operations that do not require a 
flight attendant. AMR Combs stated that many unscheduled operators do 
not employ full-time flight attendants and that a flight attendant may 
serve more than one certificate holder.
FAA Response
    In response to commenters who stated that the proposed duty period 
limitations and rest requirements should not apply to military flights 
and special charters, this final rule does not except military or 
special charter operations from duty period limitations and rest 
requirements. If a certificate holder chooses to apply the flight 
crewmember flight, duty, and rest time limitations option to flight 
attendants when conducting military and special charter flights to 
retain operational flexibility by scheduling the flight attendants with 
the flight crewmembers, Secs. 121.467(c) and 135.272(c) require that 
the flight crewmember flight, duty, and rest requirements option be 
applied to all flight operations conducted by the certificate holder.
    In response to AMR Combs and American Cyanamid Company, the FAA 
agrees with these commenters. The final rule will not apply to those 
operations where flight attendants are not required. However, all 
flight attendants who are assigned to duties in an aircraft for 
operations that require a flight attendant, including flight attendants 
in excess of the minimum flight attendant crew complement, are subject 
to duty limitations and rest requirements.
    For example, an operator conducting operations on an aircraft with 
19 passenger seats or less, which does not require a flight attendant 
under Sec. 135.107, will not be required to meet flight attendant duty 
period limitations and rest requirements for flights conducted on that 
aircraft. However, if the operator's operations specifications state 
that the operator will provide a flight attendant for flights on that 
aircraft, then the operation does require a flight attendant. 
Therefore, for any flight attendant assigned to flight duties on that 
aircraft the certificate holder is required to meet the duty period 
limitations and rest requirements of Sec. 135.273.
Duty Period Limitations
    The NPRM proposed limiting flight attendant duty periods. Proposed 
Secs. 121.466(a) and 135.273(a) defined a duty period as the period of 
elapsed time between reporting for an assignment involving flight time 
and release from that assignment by the certificate holder. The NPRM 
proposed that the time be calculated using either Coordinated Universal 
Time or the local time of the flight attendant's home base.
    Eleven commenters submitted comments supporting or recommending 
revisions to this proposed definition.
    Delta Air Lines, Southwest Air Lines, and TWU Local 556 agreed with 
the FAA's proposed definition.
    ALPA, APA, and the Coalition of Flight Attendant Unions stated that 
duty periods should include non-flight duties. ALPA noted that ground 
duties can be as fatiguing as flight duties. The Coalition of Flight 
Attendant Unions recommended that the definition of a duty period be 
replaced with: ``Any continuous period during which a flight attendant 
is required to carry out any task associated with the business of an 
aircraft operator.''
    To ensure that the definition of duty period explicitly excludes 
reserve status, ATA recommended that the following phrase be added to 
the definition of duty period: ```Duty period' does not include time 
when a flight attendant is on reserve status assignment, free of any 
specifically assigned duties other than to report for a flight 
assignment within a specified period of time, pursuant to a collective 
bargaining agreement or company work rules.''
    In addition to receiving comments on the definition of a duty 
period, the FAA also received comments on the duty period limitations 
proposed in the NPRM. The NPRM proposed to limit flight attendant duty 
periods based on the length of the duty period, the number of flight 
attendants assigned to a crew, and the amount of rest following the 
duty period. The proposed rule contained provisions (proposed 
Secs. 121.466(b) and 135.273(b)) to prohibit an operator from assigning 
a flight attendant to a scheduled duty period of more than 14 hours 
unless certain conditions are met. An operator would be allowed to 
assign a flight attendant to a scheduled duty period up to 20 hours, if 
the operator: (1) Assigns flight attendants in addition to the minimum 
flight attendant complement; and (2) schedules an extended rest period 
following the duty period.
    Thirteen commenters submitted comments on issues pertaining to 
flight attendant duty period limits. The comments addressed the use of 
``scheduled'' versus ``actual'' duty periods, addressed the effect of 
the proposed duty limits on unscheduled operators, made recommendations 
to the proposals, and provided proposed duty period limits.
    The Coalition of Flight Attendant Unions, Southwest Airlines, and 
TWU Local 556 addressed the use of ``scheduled'' duty periods as 
opposed to ``actual'' duty periods. Southwest Airlines and TWU Local 
556 agreed that the proposed duty period limitations should be 
``scheduled,'' not ``actual.'' TWU Local 556 stated that, if this 
flexibility is not retained, the following would occur: (1) Flight 
attendants would be replaced after 14 hours of actual duty, which 
inconveniences passengers and causes delays because of the need to 
locate crew replacements; (2) reserves would be placed at out stations; 
(3) crews would be rerouted to cover flights that the original crews 
cannot perform; (4) flight attendants would lose days off and have 
their schedules disrupted; (5) additional costs for crews and stranded 
passengers would be incurred; and (6) aircraft repositioning would be 
required. However, the Coalition stated that there is no justification 
for having no limit on actual hours and added that the actual number of 
flight attendant duty hours per day needs to be limited.
    AMR Combs stated that scheduled duty period limitations should 
apply only to scheduled operations with more than 19 passenger seats.
    Four commenters, including NAA, recommended revisions to the 
proposed duty period limitations. NAA recommended that a layover of 4 
to 5 hours during which a hotel room is provided should not count as 
duty time. Other comments recommended limiting duty to: (1) 16 hours in 
24 hours with 11 hours of flight time in domestic operations; (2) 30 
hours in 5 days; (3) 16 hours with no more than 10 hours of flight 
time; or (4) 12 hours for flights with multiple stops.
    The Coalition of Flight Attendant Unions submitted an alternative 
proposal to the NPRM that included duty period limitations. This 
alternative divided duty period limitations according to domestic, 
international, and long-range flights. The Coalition's alternative 
proposed to limit: (1) Scheduled duty periods on domestic flights to no 
more than 14 hours and actual duty periods to 15 hours; (2) scheduled 
duty periods on international flights to no more than 16 hours and 
actual duty periods to 17 hours; and (3) actual duty periods on long-
range flights to no more than 4 hours greater than the scheduled duty 
time, not to exceed 20 hours. The Coalition distinguished between 
domestic and international duty periods and stated that it reluctantly 
includes a 20-hour duty period for long range international flights to 
accommodate new generation aircraft, but only if additional rest is 
provided.
FAA Response
    In establishing duty period limitations, the FAA has considered a 
variety of alternatives submitted by commenters, including the 
proposals to set different limits for different types of operations. In 
an effort to establish requirements that are conducive to safety and 
compatible with air carrier operations, the FAA also has reviewed 
current industry practices used to schedule flight attendants. To 
provide the least complicated method of establishing effective 
limitations for scheduling duty periods for flight attendants, the FAA 
has decided to adopt the scheduled duty period limitations as proposed, 
with a slight modification that distinguishes cosmetic and 
international scheduled duty periods.
    The FAA has revised the definition of a duty period in this final 
rule to state that the time is calculated using Coordinated Universal 
Time or local time to reflect the total elapsed time. The phrase ``or 
the local time of the flight attendants's home base'' was replaced with 
``or local time'' to be consistent with the definition of a calendar 
day. The FAA has determined that any time zone can be used, as long as 
the operator is consistent.
    Duty period limitations are established to enhance the safety of 
the flying public by ensuring that flight attendants do not become 
overly fatigued during flight assignments. In addition, the duty period 
limitations are designed to suit all operations that require flight 
attendants without imposing a significant burden on operators.
    In response to the Coalition of Flight Attendant Unions, the final 
rule does not provide actual duty period limitations because such 
provisions may unreasonably reduce operational flexibility. However, 
the final rule requires that a flight attendant ``be given'' a 
scheduled rest period between scheduled duty periods, i.e., rest 
periods must be provided. Because duty periods are scheduled in 
combination with actual rest periods, the objective of ensuring the 
flight attendants are provided an opportunity to be rested will be met.
    After further review of the Coalition comments and an analysis of 
flight schedules, the FAA finds that scheduled duty periods of 
operations wholly within the 48 contiguous states and the District of 
Columbia should not be allowed to exceed 18 hours. The FAA is not aware 
of any scheduled duty periods for these operations that currently do 
exceed 18 hours. However, duty periods that contain one or more flights 
that land or take off outside the contiguous 48 states and the District 
of Columbia may extend up to 20 hours, provided that an extended rest 
period is scheduled following the duty period and that additional 
flight attendants are assigned to each flight segment in the duty 
period. This provision will allow air carriers to conduct extended 
long-range operations with new generation aircraft. Moreover, sections 
121.467(b)(14) and 135.273(b)(14) will allow a flight attendant for a 
domestic air carrier to continue on duty beyond the time when duty 
would normally terminate, if circumstances exist that are unanticipated 
and beyond the control of the air carrier such as adverse whether 
conditions). This same exception will apply to flag and supplemental 
operations.
    A duty period as defined in this final rule means the period of 
elapsed time between reporting for an assignment involving flight time 
and release from that assignment. In response to ATA's recommendation 
that the definition of a duty period should state that a duty period 
does not include the time when a flight attendant is assigned to 
reserve status, the FAA refers to the definition of a duty period in 
Secs. 121.467(a) and 135.273(a) of the final rule, which indicates that 
a duty period does not begin until a flight attendant reports for an 
assignment involving flight time. Reserve status is discussed in 
further detail under the heading ``Reserve Status, Stand-by Status, or 
Similar Assignments.''
    In response to NAA, all duty period assignments, including those 
assignments with a 4- to 5-hour break in duty at a hotel, must be 
assigned within duty period limitations and must meet minimum rest 
requirements. The FAA would not consider this to be a break in, or 
cessation of, the duty period.
    In response to AMR Combs, this final rule applies to operations, 
both scheduled and unscheduled, that require flight attendants. 
Therefore, operators are not required to meet duty period limitations 
and rest requirements of this final rule for operations that do not 
require a flight attendant.
Duty Period Following Reduced Rest
    Sections 121.466(i) and 135.273(i) of the NPRM proposed that an 
operator be permitted to reduce a 12-hour rest period to 10 hours 
following a duty period of more than 14 hours. In conjunction with this 
proposed provision, the FAA also proposed Secs. 121.466(j) and 
135.273(j), which would limit the scheduled duty period following a 10-
hour reduced rest period to less than 14 hours.
    ATA, Delta Air Lines, and NACA submitted comments on limiting duty 
periods following reduced rest. The commenters recommended that the FAA 
permit an operator to schedule a 16-hour duty period following a 
reduced rest period of 10 hours. ATA noted that this flexibility is 
needed for international operations.
    Delta Air Lines also recommended that the phrase ``14 or more 
hours'' appearing in proposed Secs. 121.466(j) and 135.273(j) be 
replaced with ``no more than 14 hours.'' Delta noted that the proposal 
would limit the duty period following reduced rest to 13 hours 59 
minutes.
FAA Response
    Sections 121.467(b)(9) and 135.273(b)(9) of the final rule adopt 
the provisions as proposed in Secs. 121.466(j) and 135.273(j) of the 
NPRM, except that the provisions are revised, in response to Delta 
Airlines' comment, so that an operator may not schedule a flight 
attendant for a duty period of more than 14 hours following reduced 
rest. This revision permits an operator to assign a flight attendant to 
a duty period of up to and including 14 hours following a reduced rest 
period of 10 hours.
    The FAA does not agree with those commenters that state that an 
operator should be allowed to schedule a 16-hour duty period following 
a reduced rest period of 10 hours. This was not proposed in the notice 
as it might promote problems of cumulative fatigue.
Duty Time That Exceeds Scheduled Duty Time When Beyond the Certificate 
Holder's Control
    Sections 121.466(o) and 135.273(o) proposed that a flight attendant 
would not be considered scheduled for duty in excess of duty time 
limitations if the flights to which the flight attendant is assigned 
are scheduled and normally terminate within the limitations but, 
because of circumstances beyond the control of the domestic, flag, or 
supplemental air carrier or commercial operator (such as adverse 
weather conditions), are not at the time of departure expected to reach 
their destination within the scheduled time.
    ALPA, APA, the Coalition of Flight Attendant Unions, Southwest 
Airlines, and TWU Local 556 commented on this provision.
    ALPA and APA stated that the maximum duty period limit should not 
be exceeded by more than 2 additional hours regardless of circumstances 
beyond the control of the operator.
    The Coalition of Flight Attendant Unions stated that this provision 
is unacceptable. The Coalition further stated that operators consider 
all delays outside their control.
    Southwest Airlines and TWU Local 556 stated that this provision 
should apply to a flight attendant who is reassigned after reporting 
for work and the reassignment is beyond the operator's control.
FAA Response
    The FAA has adopted this provision as proposed so that air carriers 
will not be penalized for operational delays such as those due to 
weather and air traffic control. The FAA recognizes that delays are 
costly and that operators avoid delays whenever possible. Sections 
121.467(b)(14) and 135.273(b)(14) of this final rule apply to flights 
that are assigned and scheduled and that normally terminate within 
allowable duty limitations. However, this provision does not apply to 
operational delays relating to flight attendant staffing problems. A 
flight attendant's duty period begins when the flight attendant reports 
for a flight assignment and ends when the flight attendant is released 
by the air carrier. Changes to a flight attendant's schedule after a 
duty period begins must be made in accordance with the duty period 
limitations and rest requirements set forth in this final rule. In 
addition, if a flight attendant reports for duty and is later 
reassigned, the scheduled duty time before reassignment must be counted 
as part of the total duty period.
    Example: A flight attendant is scheduled for a 13-hour duty period 
on flight staffed with the minimum cabin crew complement. The duty 
period consists of two flight segments--a flight from New York to 
Frankfurt followed by a flight from Frankfurt to Rome. Because of 
adverse weather conditions, the flight leaving New York is delayed 2 
hours, causing the flight attendant's duty period to exceed the 
scheduled 14-hour duty period limitation. Although it is apparent at 
the time of departure that the flight attendant's duty period will 
exceed 14 hours, completion of the assignment will still comply with 
duty period limitations, because the flight attendant was scheduled and 
assigned to flights that normally terminate within the allowable duty 
period limitations.
    However, if, for example, the flight attendant is reassigned in 
Frankfurt to a flight to Athens, the flight attendant's revised 
scheduled duty period cannot exceed a total of 14 scheduled hours, 
unless the flight attendant crew is augmented in accordance with 
Secs. 121.467 (b)(4), (b)(5), or (b)(6), as appropriate, and each 
flight attendant is given the minimum required rest. The flight 
attendant's duty period did not start over in Frankfurt because of the 
reassignment.
Rest Period Requirements
    The FAA received numerous comments on issues related to the rest 
requirements proposed in the NPRM. Commenters addressed issues 
including the definition of a rest period, scheduled rest versus actual 
rest, minimum rest, reduced rest, subsequent rest, relief from duty in 
air transportation and air commerce for 24 consecutive hours of rest in 
any 7 consecutive calendar days, and on-board rest requirements.
    The NPRM defined a rest period as the period when a flight 
attendant is free of all restraint or duty for a domestic, flag, or 
supplemental air carrier or commercial operator and is free of all 
responsibility for work or duty should the occasion arise. ATA, the 
Coalition of Flight Attendant Unions, and Southwest Airlines 
recommended revisions to the definition of rest period. The comments 
submitted by ATA and the Coalition of Flight Attendant Unions addressed 
reserve status in their recommended definitions of rest. Southwest 
Airlines stated that the definition of rest period should be defined as 
actual hours of rest, not scheduled hours of rest. Two commenters, 
including Delta Airlines, agreed with the definition of rest period as 
proposed in the NPRM.
    The NPRM proposed requirements for scheduling rest and reduced rest 
periods. Sections 121.466 (c) and (h) and 135.273 (c) and (h) of the 
NPRM proposed requiring that a flight attendant scheduled for 14 hours 
or less of duty be given 9 consecutive hours of rest, and that a flight 
attendant scheduled for more than 14 hours but less than 20 hours be 
given 12 consecutive hours of rest. Proposed Secs. 121.466 (d) and (i) 
and 135.273 (d) and (i) proposed permitting an air carrier or 
commercial operator to reduce these rest periods to 8 and 10 
consecutive hours, respectively. Three commenters (Southwest Airlines, 
TWU Local 556, and TWU of America) supported the minimum rest 
requirements proposed in the NPRM and also indicated that the rest 
requirements should not be increased.
    The RAA expressed concern that the requirement to provide 9 hours 
of rest for duty periods of more than 14 hours implies that a flight 
attendant who reports for a flight that is canceled is required to 
receive 9 hours of rest before the next duty period begins.
    Commenters, including APA and individual flight attendants, 
indicated that the actual time available for rest during a rest period 
is often less than the scheduled rest period and may be as much as 2 to 
3\1/2\ hours less than the number of hours scheduled in the rest 
period. The commenters stated that this often occurs because of time 
lost due to assisting passengers in deplaning, travel to and from a 
rest facility, and other activities such as eating. One commenter 
stated that it may take 35 minutes to 1 hour for passengers to deplane, 
for the crew to gather its belongings, and for travel to the hotel; 1 
hour to eat; and 1 to 1\1/2\ hours to prepare for duty again and travel 
back to the airport.
    The FAA received several alternatives to the proposed rest 
requirements. APA recommended that a flight attendant scheduled for a 
duty period of 14 hours or less be given a scheduled rest period of at 
least 10 consecutive hours. The rest period could be reduced but not 
scheduled as a reduced rest period as long as the rest period is 
reasonably calculated to provide 8 consecutive hours at a suitable rest 
facility and the flight attendant is provided a subsequent rest period 
of at least 11 consecutive hours. Under the APA proposal, scheduled 
rest periods and reduced rest periods would have to occur during the 
24-hour period preceding the scheduled end of a duty period. APA 
recommended that a flight attendant scheduled for a duty period of more 
than 14 hours but no more than 18 hours be given a scheduled rest 
period of at least 12 consecutive hours. This rest period could not be 
reduced and must occur after the completion of the scheduled duty 
period and immediately prior to the commencement of the subsequent duty 
period. The Coalition of Flight Attendant Unions proposed rest 
requirements based on domestic and international operations (see the 
discussion of Domestic and International Operations). The Coalition of 
Flight Attendant Unions' proposal recommended a minimum of 10 hours of 
rest following domestic flights, 12 hours of rest following 
international flights, and a rest period equal to twice the scheduled 
flight time for long-range international flights. The Coalition of 
Flight Attendant Unions' proposal did not include a provision for 
reduced rest. RAA requested that minimum rest requirements for flight 
attendants be aligned with flight crewmember requirements. One 
commenter suggested that a rest period should be at least 9\1/2\ hours 
at a hotel or 12 hours from the time of release to the beginning of the 
next report. Another commenter stated that the proposed minimum 
subsequent rest is satisfactory for domestic flights but not realistic 
for international flights. The commenter suggested that the rest period 
following international flights should be 24 hours.
    Several commenters recommended that the FAA establish provisions 
for on-board rest. APA recommended that a domestic, flag, or 
supplemental air carrier or commercial operator be permitted to assign 
a flight attendant to a scheduled duty period of more than 14 hours, 
but no more than 16 hours, if the inflight duties assigned to flight 
attendants by the air carrier or commercial operator were such that 
each of the cabin crew could be free of all duty for ``25 percent of 
the scheduled block time less 1 hour.'' APA stated that reclining seats 
suitable for rest reserved for 25 percent of the assigned attendant 
complement would have to be available throughout the flight. APA also 
recommended that a domestic, flag, or supplemental air carrier or 
commercial operator be permitted to assign a flight attendant to a 
scheduled duty period of more than 16 hours, but no more than 18 hours, 
if the inflight duties assigned to flight attendants by the air carrier 
or commercial operator were such that each of the cabin crew could be 
free of all duty for ``33 percent of the scheduled block time less 1 
hour.'' APA added that reclining seats suitable for rest reserved for 
33 percent of the assigned attendant complement would have to be 
available throughout the flight. The Coalition of Flight Attendant 
Unions recommended that a flight attendant be provided at least 1 hour 
of continuous rest for any flight segment scheduled for 8 or more hours 
of flight time, and that a passenger seat or bunk be assigned for crew 
rest.
FAA Response
    This final rule adopts the definition of rest period and the 
minimum rest requirements as proposed in the NPRM. The FAA has 
considered the various rest requirement alternatives proposed by 
commenters and has determined that the rest requirements proposed in 
the NPRM and adopted in this final rule are adequate to ensure that 
flight attendants are provided the opportunity to be sufficiently 
rested to perform their routine and emergency safety duties without 
imposing a significant burden on operators. A discussion of the 
comments recommending that reserve status be addressed in the 
definition of rest is contained under the heading, ``Reserve Status, 
Stand-by Status, or Similar Assignments.''
    In response to Southwest Airlines' comment that rest should be 
``actual'' hours of rest and not ``scheduled,'' the FAA considers that 
the opportunity to rest, as provided by the rest period, to be 
``actual'' rest. As proposed in the NPRM, this final rule requires that 
a flight attendant ``be given'' a scheduled rest period. This provision 
makes the operator responsible for ensuring that a flight attendant is 
scheduled for and receives the scheduled rest period. The FAA 
recognizes that how the flight attendant utilizes this rest period 
cannot be regulated. Requiring operators to schedule rest periods 
ensures that flight attendants know in advance when rest periods will 
occur and that they will be of a specified duration.
    A minimum rest period of 9 consecutive hours is required for all 
duty period assignments of 14 hours or less, unless the rest period is 
reduced in accordance with Sec. 121.467(b)(3) or Sec. 135.273(b)(3). A 
flight attendant who reports for duty to find that the flight has been 
canceled would have begun a duty period and would require minimum rest. 
However, in response to RAA's concern, a carrier could either keep the 
flight attendant on duty for reassignment or release the flight 
attendant for a complete rest period.
    Rest periods are required to occur between the completion of a 
scheduled duty period and the commencement of a subsequent duty period. 
Consequently, this final rule does not require that a required rest 
period be given immediately prior to a flight assignment. Because duty 
periods are defined as assignments involving flight time, a rest period 
is not required following assignments that do not involve flight time, 
such as training or ground duty assignments.
    In response to commenters who indicated that the actual time 
available to rest is typically less than scheduled rest, the FAA 
considers a flight attendant to be free of all restraint or duty upon 
release from an assignment involving flight time. The FAA understands 
that the time available for sleep during a rest period may vary 
depending on the amount of time a flight attendant spends in other 
activities during the rest period. The FAA also recognizes that it 
cannot compel a flight attendant to use rest periods for actual rest.
    Additionally, this final rule regulates the frequency and duration 
of required rest periods. This final rule does not regulate the quality 
of rest facilities nor does it require certificate holders to provide 
on-board rest for flight attendants.
Reduced Rest
    Sections 121.466 (d) and (i) and 135.273 (d) and (i) of the NPRM 
included provisions for operators to schedule 8-hour and 10-hour 
reduced rest periods in conjunction with certain scheduled duty period 
limitations. ALPA stated that a rest period should never be scheduled 
for less than 10 consecutive hours. However, ALPA believes that it may 
be permissible for an operator to reduce a rest period to less than 10 
hours because of circumstances beyond the control of the certificate 
holder. APA opposed the concept of reduced rest and stated that an air 
carrier or commercial operator should not be permitted to schedule a 
reduced rest period.
FAA Response
    The FAA has adopted the reduced rest provisions as proposed. This 
final rule permits an air carrier or commercial operator to schedule a 
flight attendant for reduced rest. However, no flight attendant will 
receive a rest period of less than 8 hours. This provision enables 
operators to retain a certain degree of scheduling flexibility. The 
reduced rest provision is adopted in conjunction with the requirement 
to schedule a longer rest period subsequent to an 8- or 10-hour reduced 
rest period. Together, these provisions prevent a flight attendant from 
being assigned two consecutive reduced minimum rest periods and are 
designed to protect flight attendants by minimizing the effects of 
cumulative fatigue.
24-Consecutive-Hour Rest Period During Any 7 Consecutive Calendar Days
    Sections 121.466(n) and 135.273(n) of the NPRM proposed that a 
certificate holder be required to relieve a flight attendant engaged in 
air transportation or air commerce from all further duty for at least 
24 consecutive hours during any 7 consecutive calendar days. For 
convenience, hereafter, this requirement will be referred to as the 24-
hour-in-7-day rest requirement. Proposed Secs. 121.466(a) and 
135.273(a) of the NPRM defined a calendar day as the period of elapsed 
time, using Coordinated Universal Time or local time, that begins at 
midnight and ends 24 hours later. Labor organizations, operators, and 
an association commented on the proposed 24-hour-in-7-day rest 
requirement.
    Several of the comments submitted included discussion of the term 
``calendar day.'' ATA stated that the term ``calendar day'' is 
confusing because it is unclear on which day an assignment begins or 
ends. APA stated that the term calendar day should specify that the 
local time used is that of the flight attendant's home base. In the 
Coalition of Flight Attendant Unions' alternative to the NPRM, the 
Coalition deleted the definition of the term ``calendar day'' but 
retained the provision for 24 consecutive hours of rest in 7 
consecutive calendar days.
    ATA and Delta Air Lines recommended that the FAA revise the 
proposed 24-hour-in-7-day rest requirement by replacing the phrase 
``every 7 consecutive calendar days'' with the phrase ``every 168-
consecutive-hour period.''
    Southwest Airlines and TWU Local 556 requested that the final rule 
permit a flight attendant to voluntarily waive the 24-hour-in-7-day 
rest requirement in order to be able to work extra hours. Southwest 
Airlines states that, if flight attendants cannot waive this provision, 
Southwest would be required to hire an additional 100 flight attendants 
at an initial cost of $710,000 and an annual recurring cost of 
$660,000. TWU Local 556 stated that they applied this provision to a 
sample of 13 flight attendant schedules for February 1993. According to 
TWU Local 556, if the 13 flight attendants were not permitted to fly 
their schedule, which had been altered to include extra flights, each 
flight attendant would have lost $11,063 in extra annual income. The 
total lost income for 2,200 flight attendants would be $24 million.
    ATA and Delta Air Lines recommended that the FAA include a 
provision in the final rule similar to a statement included in the 
preamble to the NPRM that indicated that the requirement for a 24-
consecutive-hour rest period in any 7 consecutive calendar days could 
be postponed under certain circumstances.
    AMR Combs and American Cyanamid Company noted that current 
Secs. 135.267(f) and 135.269(d) require unscheduled operators to 
provide flight crewmembers with at least 13 rest periods of at least 24 
consecutive hours in each calendar quarter. AMR Combs stated that the 
24-hour-in-7-day rest requirement proposed in the NPRM only should 
apply to scheduled operations. American Cyanamid Company suggested that 
flight attendants could be required to meet pilot weekly rest 
requirements as an alternative.
    Other comments submitted included: (1) A recommendation by TWU 
Local 556 that the FAA could require four 24-hour breaks in 30 days or 
require a 12-hour rest preceding the seventh duty day; and (2) a 
Carnival Airlines flight service schedule indicating that a flight 
attendant had been scheduled for 11 consecutive days of duty without 
receiving a 24-consecutive-hour rest period.
FAA Response
    The 24-hour-in-7-day rest requirement is designed to supplement 
daily rest requirements and to ensure that flight attendants receive 
the opportunity to obtain adequate rest. The FAA proposed the 
definition of a calendar day to provide a unit of measure that could be 
used to determine whether the 24-hour-in-7-day rest requirement is met. 
In response to ATA's concern that the term ``calendar day'' causes 
confusion, the FAA refers to the definition of ``calendar day'' in 
Secs. 121.467(a) and 135.273(a) of the final rule, which indicates that 
a calendar day begins at midnight and ends 24 hours later at the next 
midnight. ``Seven consecutive calendar days'' as used in Secs. 121.467 
and 135.273 of this final rule means a period of 7 consecutive days 
beginning at midnight on the first day and ending at midnight 7 days 
later. In response to APA's recommendation that the definition of 
calendar day specify that the local time be that of the flight 
attendant's home base, the FAA has determined that any time zone can be 
used to determine whether the 24-hour-in-7-day rest requirement is met, 
as long as the carrier is consistent. In other words, a certificate 
holder may not manipulate the use of time zones when calculating 7 
consecutive calendar days so as to vary the number of hours that 
comprise any 7 consecutive calendar days.
    The FAA has considered the commenters' request to replace the 
proposed 7 consecutive calendar days with a 168-consecutive-hour 
period. The FAA notes that the NPRM used language consistent with the 
language contained in the current flight crewmember flight time 
limitations rule. The FAA has decided that it should not introduce at 
this final rule stage an inconsistency between the flight crewmember 
flight time limitations rule language and the flight attendant duty 
period limitations and rest requirements rule language. The FAA will 
consider whether rulemaking should be initiated to replace 7 
consecutive calendar days with 168-consecutive-hours.
    The FAA has reviewed requests to permit flight attendants to 
voluntarily waive the 24-hour-in-7-day rest requirement. The FAA has 
not included that alternative in this final rule because the purpose of 
requiring 24 consecutive hours free from duty in any 7 consecutive 
calendar days is to ensure that flight attendants receive the 
opportunity to obtain adequate rest. As with rest requirements 
following reduced rest, the requirement for 24 consecutive hours of 
rest in any 7 consecutive calendar days is designed to protect flight 
attendants by minimizing the effects of cumulative fatigue.
    In response to comments received from ATA and Delta Airlines, the 
FAA has determined that it is not necessary to include in this final 
rule provisions for permitting the 24-hour-in-7-day rest requirement to 
be delayed. This final rule imposes restrictions for flight attendants 
that parallel the restrictions that currently exist for flight 
crewmembers. The absence of provisions to permit the 24-hour-in-7-day 
rest requirement to be delayed does not preclude a flight attendant 
from completing a duty period assignment that has extended into the 
seventh calendar day because of a delay that is beyond the control of 
the operator. In addition, the 24-hour-in-7-day rest requirement may be 
delayed for reasons such as deadheading, assignment to training, and 
others. However, if the requirement is delayed, the flight attendant 
must be given the 24-consecutive-hour rest period before beginning any 
subsequent duty period assignment.
    In response to unscheduled operators, the FAA notes that 
unscheduled part 135 operators conducting operations that require 
flight attendants have the option to apply the flight crewmember flight 
time limitations to flight attendants instead of using the duty period 
limitations and rest requirements contained in this final rule. 
Sections 135.267(f) and 135.269(d) require certificate holders to 
provide each flight crewmember with at least 13 rest periods of at 
least 24 consecutive hours each in each calendar quarter. Among other 
requirements, operators that choose to apply flight crewmember 
requirements to flight attendants would be required to provide flight 
attendants with at least 13 rest periods of at least 24 consecutive 
hours in each calendar quarter instead of relief from duty for 24 
consecutive hours every 7 consecutive calendar days.
    Comments on the costs associated with the 24-hour-in-7-day rest 
requirement are addressed in the Regulatory Evaluation Summary.
Compensatory Rest Periods
    Although there was no specific proposal in the notice, the FAA 
requested comments on the feasibility of establishing compensatory rest 
periods for flight attendants when scheduled duty periods are exceeded. 
ATA, the Coalition of Flight Attendant Unions, and Delta Air Lines 
opposed the establishment of compensatory rest periods.
FAA Response
    In response to the comments submitted, the FAA will not mandate 
compensatory rest periods in this final rule. The FAA has determined 
that compensatory rest is not necessary, because the duty period 
limitations and rest requirements contained in this final rule ensure 
that flight attendants receive the opportunity to be adequately rested 
to perform safety duties.
Reserve Status, Stand-by Status, or Similar Assignments
    The FAA recognizes that current industry practice varies with 
regard to the use of these terms and their relationship to duty or 
rest. In the NPRM, the FAA requested comments on the most appropriate 
way to address reserve status, stand-by status, or a similar 
assignment. The FAA received 13 comments, primarily from air carrier 
associations and labor organizations. Commenters described different 
types of reserve status and suggested situations when reserve should be 
considered duty or rest.
    ATA recommended adding the following phrase to the definition of 
rest period: ``except that reserve status assignments shall be 
considered `rest' for purposes of this rule, provided that the only 
work-related restriction shall be to report for a flight assignment 
within a specified period of time pursuant to a collective bargaining 
agreement or company work rules.'' The Coalition of Flight Attendant 
Unions recommended that the definition of rest period be revised to 
``the time period free of all restraint or duty from a domestic, flag, 
or supplemental air carrier or commercial operator and free of all 
responsibility, or interruption by, work or duty.''
    In addition, commenters indicated that different types of reserve 
status including ``call-in'' reserve and ``on-call'' reserve are 
commonly found in the aviation industry. As described by commenters, 
call-in reserve requires that a flight attendant contact, or be 
available to be contacted by, the operator at designated times for 
flight assignments. The commenters added that on-call reserve typically 
requires that a flight attendant be available for an assignment on 
short notice (usually within 1 hour) if contacted by the operator.
    A majority of the commenters on this issue discussed whether 
reserve status should be considered rest. ATA, NACA, and Southwest 
Airlines stated that the time a flight attendant is assigned to reserve 
status and is not assigned to a duty period should be considered rest 
for the purpose of meeting the 24-hour-in-7-day rest requirement 
proposed in Sec. 121.466(n) of the NPRM. RAA stated that the type of 
reserve in which a person must contact the company for future 
assignments--rather than being available for an assignment on short 
notice--should be considered rest because it is free of all duty except 
for the possibility of communication with the operators. Two individual 
commenters stated that the time a flight attendant spends on reserve 
should not be considered rest.
    Four of the commenters, including ATA, Delta Air Lines, and RAA, 
commented on whether reserve status should be considered part of a duty 
period. ATA and Delta Air Lines stated that the time a flight attendant 
spends on reserve should not be considered a duty period. ATA noted 
that, if reserve is considered duty, operators will need to increase 
staff by 20 to 30 percent. ATA estimates that the annual cost would be 
$100 to $130 million for salaries, benefits, and associated training 
and administrative costs. Delta Air Lines expressed concern that if 
``on-call'' reserve is considered duty, flight attendants would request 
at-home pay. RAA stated that the type of reserve in which a person is 
expected to report on short notice should be considered duty. TWU Local 
556 stated that duty time for a reserve flight attendant should be 
calculated from actual report time to release time for a flight 
assignment.
FAA Response
    In response to the commenters who stated that reserve status should 
be considered rest, the FAA notes that the time during which a flight 
attendant is responsible for contacting a certificate holder or for 
being available to be contacted by a certificate holder for an 
assignment (e.g., reserve or stand-by status) does not meet any rest 
period requirements, because the FAA has defined a rest period as free 
of all restraint or duty and free of all responsibility for work or 
duty should the occasion arise.
    Specifically in response to ATA's, NACA's, and Southwest Airlines' 
suggestions that reserve assignments should fulfill the 24-hour-in-7-
day rest requirement if no duty period is assigned, the FAA reiterates 
that rest period requirements are not met when a flight attendant is 
assigned to reserve status even if the flight attendant is not given a 
duty period assignment. A duty period, as defined in this final rule, 
does not begin until a flight attendant reports for an assignment 
involving flight time. For example, a flight attendant who has been 
assigned to reserve status for 24 hours but has not reported for a duty 
period assignment during that time will not have satisfied the 24-hour-
in-7-day rest requirement. The rest requirement is not satisfied, 
because the reserve assignment is a restraint and includes present 
responsibility for work as a flight attendant if the occasion arises.
    Some commenters stated that reserve status should not be restricted 
by duty period requirements. The FAA refers the commenters to the 
definition of duty period in Secs. 121.467(a) and 135.273(a) of the 
final rule, the first sentence of which reads: ``Duty period means the 
period of elapsed time between reporting for an assignment involving 
flight time and release from that assignment. * * *'' It should be 
clear that reserve status alone does not meet the definition of duty 
period. On the other hand, it also should be clear that reserve status 
may not be performed during a rest period. The definition of rest 
period in Secs. 121.467(a) and 135.273(a) of the final rule states that 
``Rest period means the time period free of all restraint or duty for a 
domestic, flag, or supplemental air carrier or commercial operator and 
free of all responsibility for work or duty should the occasion 
arise.''
Augmented Cabin Crews
    This final rule permits operators to schedule flight attendants for 
duty periods of more than 14 hours provided an operator: (1) Assigns 
flight attendants in addition to the minimum flight attendant 
complement required for the flight or flights in that duty period under 
the certificate holder's operations specifications; and (2) schedules 
an extended rest period following the duty period.
    Ten commenters submitted comments on the proposed augmented cabin 
crew requirements addressing: (1) The concept of augmenting cabin crews 
in proportion to the type of aircraft; (2) the relationship between 
augmented cabin crews and flight attendant fatigue; and (3) the effect 
of augmented crew requirements on unscheduled operators.
    APA, NAA, and RAA noted that the proposed augmented cabin crew 
requirements are not based on the size of the aircraft. APA stated that 
if the FAA intends the provision for augmented cabin crews to be used 
only for long-range operations, this should be clarified in the final 
rule. APA noted that, under the proposed provisions, one flight 
attendant would be added to either a two-person crew or an eight-person 
crew. NAA noted that, one additional flight attendant on a Boeing 757 
is a 20 percent increase in crew; one additional flight attendant on a 
wide-body airplane is a 7 percent increase in crew. NAA recommended 
that the FAA distinguish between wide-body and narrow-body airplanes by 
requiring one additional flight attendant for any duty period between 
14 and 20 hours on a narrow-body airplane. RAA stated that operators of 
airplanes that require one or two flight attendants should not be 
required to augment cabin crews in order to schedule duty periods 
longer than 14 hours. RAA added that a passenger seat will be needed 
for an additional flight attendant. RAA also noted that regional 
operators schedule some duty periods longer than 14 hours; however, 
many of these include an intermediate rest period.
    APA, the Coalition of Flight Attendant Unions, and RAA addressed 
the relationship between augmented cabin crews and fatigue. APA and the 
Coalition stated that a larger crew does not necessarily result in a 
less fatigued crew and noted that American Airlines, Trans World 
Airlines, United Air Lines, and USAir currently assign flight 
attendants in addition to the minimum crew complement. APA and the 
Coalition of Flight Attendant Unions noted that the proposal does not 
require an operator to provide a flight attendant with inflight rest. 
RAA stated that requiring augmented cabin crews for the purpose of 
reducing fatigue has been inadequately justified.
    ATA and Delta Air Lines stated that the rule should permit a flight 
to operate if an augmented crew is assigned but not present for a 
flight because of unforeseen circumstances (e.g., illness or injury 
during a layover). Delta suggested that 1 hour of on-board crew rest 
for the remaining flight attendant crew could be provided in this 
circumstance.
    AMR Combs noted that a change is needed for on-demand operators. 
They stated that a ``larger'' aircraft such as a Gulfstream or a 
Challenger cannot accommodate up to four flight attendants. AMR Combs 
stated that these operators would either apply for an exemption or not 
use a flight attendant.
FAA Response
    This final rule provides scheduling flexibility by permitting an 
operator to schedule a flight attendant for a duty period of more than 
14 hours if the flight attendant crew is augmented in accordance with 
Sec. 121.467 (b)(4), (b)(5), or (b)(6), or Sec. 135.273 (b)(4), (b)(5), 
or (b)(6). The augmented flight attendant crew provision permits 
extended duty periods to accommodate certain operational requirements 
such as those for long-range international flights, but this provision 
also may be applied to domestic operations.
    The provision for augmented cabin crews is designed to reduce 
fatigue by decreasing flight attendant work load on a flight and by 
providing an extended rest period following a long duty day. Although 
the FAA recognizes that the provision will not require flight attendant 
crews to be augmented proportionally for each aircraft type, it 
provides the least complicated method for reducing fatigue and 
accommodating certain operational requirements. Therefore, in this 
final rule, the FAA adopts the provision for augmenting cabin crews on 
a flight or flights with a scheduled duty period of more than 14 hours 
but not more than 18 hours, and scheduled duty periods that do not 
exceed 20 hours for duty periods that contain one or more flights that 
land or take off outside the 48 contiguous states and the District of 
Columbia.
    In response to comments from AMR Combs, Delta Airlines, and RAA, 
this final rule contains no provision to except an operator from 
meeting minimum augmented cabin crew requirements when a flight 
attendant duty period is scheduled for more than 14 hours in operations 
that require a flight attendant. This includes instances in which a 
required crewmember is not available following a layover, e.g., due to 
illness or injury. Additionally, the use of an approved passenger seat 
is required for operators that schedule flight attendants for duty 
periods of more than 14 hours on aircraft that are not configured with 
a flight attendant jumpseat for the additional flight attendant(s).
    In response to AMR Combs' comment regarding the use of flight 
attendants in Gulfstream and Challenger aircraft, this final rule 
applies to operations that require a flight attendant. Typically, 
Gulfstream and Challenger aircraft are not configured with more than 19 
passenger seats and a flight attendant is not required to be on board. 
Therefore, flight attendants assigned to such operations are not 
subject to the duty period limitations and rest requirements in this 
final rule. In addition, operators have the option to apply flight 
crewmember flight, duty, and rest requirements to flight attendants.
Deadhead Transportation
    Proposed Secs. 121.466(m) and 135.273(m) described deadhead 
transportation as time spent in transportation, not local in character, 
that a certificate holder requires of a flight attendant and provides 
to transport the flight attendant to an airport at which that flight 
attendant is to serve on a flight as a crewmember, or from an airport 
at which the flight attendant was relieved from duty to return to the 
flight attendant's home base. Under the proposal, time spent in 
deadhead transportation is not rest.
    ATA, Delta Air Lines, and NACA requested that the final rule 
provide scheduling flexibility for flight attendants in deadhead 
transportation. ATA requested that the FAA permit: (1) Operators to 
schedule 2 hours of deadhead transportation to a domicile that is not 
counted within duty time limitations; (2) flight attendants to waive 
all duty time limitations when returning to a domicile and count the 
time as rest; and (3) flight attendants to delay the weekly rest 
requirement to return to the flight attendant's home base. Delta Air 
Lines stated that the FAA should permit a flight attendant to alter 
schedules to exceed the scheduled maximum duty time after the last 
flight segment to return to the flight attendant's home base. Delta 
also recommended that an operator be permitted to deadhead a flight 
attendant for up to 20 hours regardless of the number of assigned 
flight attendants. NACA suggested that the final rule clarify that the 
time a flight attendant spends deadheading is not limited by duty 
periods or the requirement to augment the flight attendant crew because 
no inflight duties are involved.
    ATA and NACA stated that the final rule should clarify that a 
deadheading flight attendant is not a working member of the cabin crew 
for the purpose of determining if staffing requirements must be 
augmented.
    The Coalition of Flight Attendant Unions and NACA agreed with the 
NPRM that the time a flight attendant spends in deadhead transportation 
is not rest.
FAA Response
    Deadhead transportation as adopted in Secs. 121.467(b)(12) and 
135.273(b)(12) of this final rule is not considered part of a rest 
period. This use of deadhead transportation in relation to flight 
attendant duty period limitations and rest requirements is consistent 
with the application of flight crewmember flight time limitations and 
rest requirements.
    In addition, a flight attendant scheduled for deadhead 
transportation is not assigned to duty in an aircraft and is not 
considered a working crewmember. Therefore, for the purpose of 
determining duty period limitations and rest requirements, deadhead 
transportation is not considered an assignment involving flight time 
and is not part of a duty period. In response to the comments 
submitted, the FAA reiterates that an operator is not required to 
augment flight attendant crews for flights when a flight attendant is 
assigned to deadhead transportation because the time spent in deadhead 
transportation is not part of a duty period. For example, an operator 
may schedule a flight attendant crew for a flight to Europe with a duty 
period of 14 hours. Immediately following the flight and before 
beginning a 9-hour rest period, the operator requires the flight 
attendant crew to deadhead for 2 hours to position the crew for the 
next duty period assignment. In this example, the operator is not 
required to augment the flight attendant crew because the deadheading 
portion of the assignment is not considered part of the duty period. 
However, the 2 hours spent positioning the crew for the next assignment 
are not considered part of the 9-hour rest period.
Flight Attendant Responsibility
    Proposed Secs. 121.466 and 135.273 state that a flight attendant 
may not accept a work assignment that does not meet the duty time 
limitations and rest requirements. Six commenters responded to this 
provision.
    ATA, APA, Delta Air Lines, and RAA opposed this provision. The 
commenters stated that, if the provision were adopted, flight 
attendants would be subject to FAA civil penalties. The commenters also 
expressed concern that the provision would interfere with labor-
management relations. APA noted that a flight attendant could be 
permitted to complete a flight assignment that the flight attendant 
believes to be improper and to inform the FAA at the next opportunity.
    The Coalition of Flight Attendant Unions included in its 
alternative the provision for a flight attendant to refuse a work 
assignment that does not meet the Coalition's proposed duty time 
limitations and rest requirements. In contrast, TWU Local 556, 
representing the flight attendants of Southwest Airlines, commented 
that the provision of flight attendant responsibility could place a 
flight attendant in the impossible position of risking either a fine 
from the FAA or discipline for insubordination from the airline if the 
carrier's scheduling department makes a mistake.
FAA Response
    In light of comments received, the FAA has determined that only an 
operator, not a flight attendant, should be responsible for ensuring 
that duty limitations and rest requirements are met. The FAA bases its 
decision on the fact that a flight attendant could be called upon to 
decide between the violation of a regulation and possible disciplinary 
action from the company. That misunderstanding and conflict between 
company scheduling personnel and flight attendants could occur at a 
time when flight attendants should be giving their full attention to 
the passengers. In cases in which a flight attendant is aware that an 
assignment does not meet duty period and rest requirements, the FAA 
recommends that the flight attendant bring the situation to the air 
carrier's attention. If the situation is not corrected, the flight 
attendant should then inform the FAA. However, this recommendation does 
not preclude a flight attendant from informing the FAA before 
contacting the air carrier. In addition, flight attendant duty and rest 
time records are subject to FAA review. Air carriers found to be in 
noncompliance with the regulation are subject to enforcement action.
Recordkeeping
    Sections 121.683(a)(1) and 135.63(a)(5) of the NPRM proposed 
requiring certificate holders to maintain current records on flight 
attendant duty and rest time requirements. The Coalition of Flight 
Attendant Unions, Southwest Airlines, TWU Local 556, and TWU of America 
agree with the proposed recordkeeping requirements. The Coalition of 
Flight Attendant Unions does not anticipate that the recordkeeping 
requirements as proposed in the NPRM would be unduly burdensome.
    NAA stated that the cost of tracking crew time for duty and rest 
could be very expensive. NAA noted that many small carriers do not have 
expensive computer tracking systems and cannot afford to do manual 
tracking.
    Delta Airlines stated that the one-time cost for computer software 
changes would be $368,000. NACA noted that one of its members estimates 
that the proposed recordkeeping requirements would cost $50,000 
annually.
FAA Response
    The information and recordkeeping requirements of this final rule 
are currently under review by the Office of Management and Budget. 
Provided that they are approved by OMB, the FAA adopts the 
recordkeeping requirements as proposed in the NPRM. These requirements 
will become effective when they have been approved by OMB. The FAA 
anticipates that this approval will be given soon.
    The FAA recognizes that a concern of the aviation industry has been 
the potential cost involved in tracking crew time for duty and rest 
periods. The regulation provides that carriers maintain current records 
for each flight attendant to verify compliance with flight, duty, and 
rest time periods. The FAA intends to be as flexible as possible in 
interpreting this recordkeeping requirement. Records may be maintained 
by computer, by hand documentation, or by any other method that will 
permit a carrier to assure compliance with the regulatory requirements.
    Since many carriers already track flight attendant duty periods to 
ensure that union contract or company guidelines on duty and rest time 
are met, the FAA expects that recordkeeping systems already in place 
will be sufficient to meet the recordkeeping requirements of the final 
rule with minimal modification. Carriers that do not currently track 
flight attendant duty periods will incur costs in developing 
recordkeeping systems; however, the flexibility built into the final 
rule should help to minimize these costs. Further, the FAA intends to 
assist these carriers by providing information and guidance based on 
already-implemented recordkeeping systems maintained by other air 
carriers.
Implementation Time of the Final Rule
    ATA and Delta Air Lines requested that the FAA not implement this 
final rule immediately. They noted that operators will need time to 
revise their computer programs. ATA requested a 12-month implementation 
period; Delta requested an 18-month implementation period.
FAA Response
    The FAA has considered the implementation periods proposed by ATA 
and Delta. However, in the interest of public safety, the FAA has 
determined that the final compliance date of this rule should be no 
later than March 1, 1995. Because most operators are currently using 
scheduling guidelines and tracking systems for flight attendants, the 
FAA has determined that the March 1, 1995, date is reasonable.

Additional Issues

Fatigue
    Commenters who addressed flight attendant fatigue include ATA, the 
Coalition of Flight Attendant Unions, NACA, NTSB, RAA, SCA, and 
Southwest Airlines.
    ATA emphasized that flight attendant fatigue caused by abusive 
scheduling or duty periods is not a problem in the scheduled airline 
industry. NACA, RAA, SCA, and Southwest Airlines emphasized that 
studies have found no correlation between flight attendant fatigue and 
the ability of a flight attendant to perform safety-sensitive 
functions. SCA point out that accident data do not specify flight 
attendant fatigue as a factor in delay of evacuation or in injuries or 
fatalities that occurred.
    The Coalition of Flight Attendant Unions provided a summary of 
research on circadian dysrhythmia and fatigue with an extensive 
bibliography. NTSB reiterated Recommendation I-89-1, which stated that 
the Department of Transportation should ``expedite a coordinated 
research program on the effects of fatigue, sleepiness, sleep 
disorders, and circadian factors on transportation system safety.'' 
Other commenters submitted copies of articles and recommendations 
related to fatigue.
FAA Response
    The FAA has reviewed the extensive amounts of literature provided 
by commenters on fatigue related to travel and extended work periods as 
well as to shift work. Although consideration has been given to 
numerous fatigue studies, no accident/incident data is available to 
provide a direct correlation between flight attendant fatigue and 
passenger safety. However, it is evident that fatigue may affect flight 
attendant performance and that proper scheduling practices may help 
avoid compromising flight attendant performance. The FAA recognizes 
that flight attendants perform essential safety duties and has 
determined that the requirements contained in this final rule enhance 
safety by protecting flight attendants from acute and chronic fatigue. 
This final rule addresses the potential safety problems that could 
occur if fatigued flight attendants work excessive duty hours or 
receive inadequate rest.
Industry Study
    The principal commenters who addressed the Industry Study include 
AMR Combs, American Cyanamid Company, the Coalition of Flight Attendant 
Unions, and SCA.
    American Cyanamid Company stated that the Industry Study does not 
indicate that there is a pattern of air carriers willfully scheduling 
long duty days or long series of days without a day off. The Coalition 
of Flight Attendant Unions indicated that the Industry Study has been 
used as evidence that extreme examples of scheduling abuse are isolated 
and that the actual occurrences of scheduling abuse were most likely 
under-reported because the instances provided in the Industry Study 
were ``self-selected.'' The Coalition further stated that, even though 
the instances were self-selected, the Industry Study found industry-
wide flight attendant duty and rest period problems. SCA stated that 
the Industry Study does not provide evidence to establish any 
correlation among flight attendant duty time, flight attendant safety 
duties, and risk to passengers. AMR Combs and American Cyanamid Company 
noted that the Industry Study did not consider unscheduled part 135 
operators.
FAA Response
    The FAA conducted the Industry Study to determine if scheduling 
extremes exist, and, if so, to determine the nature of the extremes, 
not to determine the statistical frequency with which they occur or to 
correlate passenger risk with extreme scheduling. Access to records was 
gained through the cooperation of air carriers. The air carriers did 
not choose individual records for examination. Based on the purpose of 
the study, records were selected for review when flight attendant 
scheduling extremes were expected to be likely. Therefore, statistical 
inferences cannot be made. However, the data contained in the Industry 
Study provides fundamental background information on flight attendant 
scheduling practices.
    The Industry Study included a review of data from major, national, 
regional, and supplemental carriers. The study did not include a review 
of unscheduled part 135 operators because relatively few of these 
operators conduct operations that require a flight attendant. As 
previously discussed, air carriers and commercial operators conducting 
operations for which the FAA does not require a flight attendant will 
not be required to comply with flight attendant duty period limitations 
and rest requirements even if flight attendants are involved in those 
operations.
International and Domestic Operations
    The proposed amendment did not make a distinction between domestic 
and international operations in determining flight attendant duty 
limitations and rest requirements. Five commenters commented on whether 
there should be a distinction between domestic and international 
operations for determining flight attendant duty period limitations and 
rest requirements. Four commenters, including the Coalition of Flight 
Attendant Unions and the International Association of Machinists and 
Aerospace Workers (IAM & AW), supported making a distinction. The 
Coalition provided definitions for a domestic flight, an international 
flight, and a long-range international flight. One commenter stated 
that flight attendants assigned to international flight require more 
rest than flight attendants assigned to domestic flights because flight 
attendants on international flights are in a state of physical 
desynchronization. Another commenter stated that duty period limits 
should be 12 hours for domestic flights and 14 hours for international 
flights. NAA stated that no distinction should be made between 
international and domestic flights because some domestic flights are as 
long as international flights and the work load is the same for the 
crew.
FAA Response
    After a review of the Coalition comments and an analysis of flight 
schedules, the FAA finds that scheduled duty periods for operations 
wholly within the 48 contiguous states and the District of Columbia 
should not be allowed to exceed 18 hours. The FAA is not aware of any 
scheduled duty periods for these operations that currently do exceed 18 
hours. However, for duty periods involving one or more flights that 
land or take off outside the 48 contiguous states and the District of 
Columbia, the duty period may not exceed 20 hours. Thus, the final rule 
makes this distinction between domestic and international operations.
Part 125 Operators
    The NPRM proposed that each flight attendant be relieved from all 
duty for at least 8 consecutive hours during any 24-hour period.
    Two commenters, including the Coalition of Flight Attendant Unions, 
addressed this proposal. The Coalition recommended that the 8-hour 
period free of duty be replaced with a 10-hour period free of duty.
FAA Responses
    Section 125.37, Duty time limitations, currently requires a flight 
crewmember to be relieved from duty for at least 8 consecutive hours 
during any 24-hour period. The final rule incorporates flight 
attendants into the current provision, thus providing parallel duty 
time limitations for flight attendants and flight crewmembers.
Rules for Flight Attendants in Other Nations
    APA, the Coalition of Flight Attendant Unions, and the IAM & AW 
noted that flight attendants in other nations have regulations that 
provide flight attendant duty time limitations and minimum rest 
requirements. APA stated that the proposed Joint Aviation Authorities 
(JAA) regulations address issues related to fatigue. The Coalition 
provided a copy of the proposed JAA rules.
FAA Response
    During the Industry Study, the FAA conducted a review of the 
International Civil Aviation Organization's (ICAO) regulations relating 
to flight attendant flight, duty, and rest times including a review of 
ICAO Circular Flight Crew Fatigue and Flight Time Limitations (52-AN/
47/6). The Industry Study identified 23 countries that have government 
regulations for flight attendant flight and duty limitations and rest 
requirements, and 24 countries that do not have such regulations. The 
FAA notes that the Joint Aviation Regulations currently do not include 
flight time limitations for flight attendants; however, the JAA have 
proposed flight time limitations for flight crewmembers and flight 
attendants that are currently under review by the European Community. 
Based on this information, the FAA has determined that flight attendant 
flight and duty limitations and rest requirements of some countries are 
less stringent than the final rule adopted by the FAA, and the 
requirements of other countries are more stringent than those being 
adopted. Therefore, the FAA considers the final rule to be within the 
range of worldwide governmental regulations governing flight attendant 
duty limitations and rest requirements.

Changes to the NPRM

    The FAA amended several provisions of the proposed rule in response 
to comments received from the public. Any changes that significantly 
altered the requirements of the duty period limitations and rest 
requirements are discussed previously and are summarized in this 
section.
    The NPRM made no distinction between domestic and international 
operations. In the final rule domestic operations are limited to up to 
18-hour scheduled duty periods. However, scheduled duty periods that 
involve one or more flights that land or take off outside the 48 
contiguous states and the District of Columbia may be scheduled up to 
20 hours, providing required augmentation is provided.
    The FAA moved flight attendant duty period limitations and rest 
requirements from proposed Sec. 121.466 in the NPRM to Sec. 121.467 in 
the final rule to facilitate the incorporation of future amendments. In 
addition, paragraphs describing duty period and rest period provisions 
in the NPRM have been revised and renumbered in the final rule to 
incorporate new and revised requirements. The FAA also revised the NPRM 
to include minor editorial changes and revised the list of subjects to 
include additional terms.
    Based on comments receive, the FAA removed the proposed requirement 
that a flight attendant be responsible for ensuring compliance with 
duty period limitations and rest requirements before accepting any 
flight assignments. The FAA determined that this is an operator's 
responsibility and not the responsibility of a flight attendant.
    The NPRM included the proposal that an operator may not assign a 
flight attendant a duty period of 14 or more hours following a 10-hour 
reduced rest period. In Secs. 121.467(b)(9) and 135.273(b)(9), the FAA 
revised the NPRM to restrict an operator from assigning a flight 
attendant to a duty period of ``more than 14 hours'' following a 10-
hour reduced rest period. This change permits an operator to assign a 
flight attendant to a duty period of up to and including 14 hours 
following the reduced rest period.
    The FAA incorporated provisions into the final rule to give 
operators the option to apply the flight crewmember flight, duty, and 
rest requirements to flight attendants. The FAA permits this option 
provided that the operator establishes written procedures that are 
referenced in the certificate holder's operations specifications for 
applying the appropriate flight crewmember flight, duty, and rest 
requirements to flight attendants.
    The following chart depicts the scheduled duty period, rest period, 
and augmented flight attendant crew requirements for this final rule.

Costs
    In the NPRM, the FAA requested additional information on the costs 
of the proposed rule. The FAA received comments from associations, 
labor organizations, and part 121 operators.
    ATA, which primarily represents part 121 scheduled operators, 
stated that the proposal would cost its members at least $8 million 
annually to revise current computer crew scheduling programs, hire 
additional personnel, extend layovers, and schedule reserves. ATA 
believes that the costs were understated in the NPRM and noted that 
they did not include an inflation factor. ATA indicated that the 15-
year cost of the proposed rule would be $88,947,099 using a 7-percent 
discount rate and a 3-percent inflation rate. RAA stated that the costs 
associated with the proposed rule are significantly understated. In 
addition, RAA believes that the economic effect of the proposed rule 
should reflect the cost burden of other recent rulemakings. NACA stated 
that the proposal would cost one of its members an estimated $372,000 
annually for additional staffing and $50,000 annually to meet 
recordkeeping requirements.
    The Coalition of Flight Attendant Unions stated that the median 
flight attendant salary, based on the average salary for supplemental 
air carrier flight attendants represented by the Association of Flight 
Attendants (AFA), is $18,461. According to the Coalition, if 6,000 
flight attendants are hired by supplemental operators, the cost in 
salaries will be $1,107,660 [sic]. The Coalition noted that this is one 
tenth the cost of random drug testing.
    Delta Airlines, a scheduled part 121 operator, indicated that the 
initial cost to comply with the proposed rule would be $2,863,416. This 
cost includes the cost of hiring 36 additional flight attendants, 
estimated at $1,348,000; paying flight attendants during deplaning, 
estimated at $749,000; providing additional meals, estimated at 
$400,000; and modifying computer software, estimated to be a one-time 
cost of $367,000. Delta estimates that the annual cost to comply with 
the proposed rule would be $2.5 million.
    Sun Country Airlines, an unscheduled part 121 operator, stated that 
it would be required to augment cabin crews on domestic flights more 
often than it now does. Sun Country Airlines also stated that, if the 
NPRM had been effective in 1992, the carrier would have hired an 
additional 34 flight attendants and the cost to domestic operations 
would have been $2.6 million in salaries, benefits, training, hotels, 
meals, deadhead travel, and administrative burden. Sun Country Airlines 
pointed out that the NPRM estimated that supplemental operators would 
absorb 60 percent of the proposal's costs while supplemental operators 
employ only 1 percent of all flight attendants.
    Great American Airways, an unscheduled part 121 operator, stated 
that the proposed rule would impose substantially greater costs on 
supplemental air carriers. Positioning flight attendants would become a 
major expense for supplemental operators. Unanticipated schedule and 
routing changes could severely curtail current flexibility. However, 
Great American Airways stated that the disruptions mentioned above 
would be minimized if supplemental air carriers had the option to apply 
the same work rules to both flight attendants and pilots. Great 
American Airways estimates that the total cost savings that would be 
derived from implementing a single set of duty limitations for its 
cabin and flight crewmembers, as opposed to adopting the requirements 
proposed in the NPRM, would be more than $100,000 annually.
FAA Response
    The comments that address the costs associated with this final rule 
are addressed in the Regulatory Evaluation Summary.

Paperwork Reduction Act

    Information collection requirements for parts 121, 125, and 135 
have been previously approved by the Office of Management and Budget 
(OMB) under the provisions of the Paperwork Reduction Act of 1980 (Pub. 
L. 96-511) and have been assigned OMB Control Numbers as follows: For 
part 121, OMB Control Number 2120-0008; for part 125, OMB Control 
Number 2120-0085; and for part 135, OMB Control Number 2120-0039. The 
FAA has prepared changes to these control numbers to reflect the 
additional paperwork requirements of this final rule and has submitted 
these changes to OMB.
    In completing this rulemaking, the FAA has been mindful that it is 
the policy of the agency and the Administration to avoid imposing 
unnecessary paperwork burdens on industry. To that end, the FAA has 
carefully considered all comments on recordkeeping and has made every 
attempt to minimize the paperwork burden for carriers. For example, 
allowing carriers to employ a single scheduling system for entire 
crews--pilots and flight attendants--will enable them to avoid 
maintaining two separate duty schedules. Indeed, for many carriers, the 
FAA believes the final rule will create little or no net additional 
paperwork.

Regulatory Evaluation Summary

    The FAA has determined that this rule: (1) Is a significant 
regulatory action as defined in the Executive Order; (2) is significant 
as defined in Department of Transportation's Regulatory Policies and 
Procedures; (3) would not have a significant impact on a substantial 
number of small entities; and (4) would not constitute a barrier to 
international trade. These analyses, summarized below, are available in 
the docket.

Cost-Benefit Analysis

Benefits
    The FAA expects the final rule to help ensure that flight 
attendants are rested and alert when performing emergency and routine 
safety related duties and thereby reduce injuries and fatalities in air 
carrier accidents. However, as in the NPRM, the FAA has not quantified 
the benefits associated with this rulemaking because there is a lack of 
accident/incident data that can be used to directly correlate flight 
attendant fatigue with passenger fatalities and injuries. Instead, the 
FAA has examined the potential benefits of this rulemaking from a 
qualitative perspective.
Increased Safety
    The FAA received comments both supporting and opposing the 
correlation between flight attendant duty period limitations and rest 
requirements and passenger safety. One commenter stated that fatigue 
increases during the work period, and duty times that exceed 12 hours 
for domestic flights and 14 hours for international flights can be 
expected to potentially derogate safety performance. Another commenter 
stated that the FAA has provided no sufficient foundation for 
concluding that the absence of the proposed regulations constitutes a 
derogation of aviation safety, and that the absence of any experience 
in which a flight safety problem was attributable to undue flight 
attendant fatigue is a strong argument that no such problem exists.
FAA Response
    The FAA agrees with commenters who stated that inadequate rest or 
excessive duty periods could derogate safety. However, the commenters 
did not define acceptable or unacceptable levels of risk, and did not 
provide any justification for the distinction. Because quantifiable 
data was not available, the FAA was unable to calculate the 
quantitative benefits of the rule.
    The FAA recognizes that inadequate rest periods for flight 
attendants could create a potential safety problem. Therefore, the FAA 
expects that this final rule will ensure that flight attendants receive 
the opportunity to be rested and alert when performing emergency and 
routine safety-related duties, thereby reducing passenger and crew 
injuries and fatalities.
Increased Worker Productivity
    The Coalition stated that, in addition to improving the safety of 
air travel, the regulatory evaluation should take into account the cost 
savings from improved worker productivity. That commenter also stated 
that a careful review of various studies would likely reveal that the 
benefits of more reasonable duty hours and adequate rest include 
decreased absenteeism and health problems related to fatigue. The 
Allied Pilot Association stated that ``the welfare of regulated 
employees ought to be one of the concerns of rulemakers.''
FAA Response
    The FAA has examined the impact of improved worker productivity as 
it relates to safety and has determined that reduced rest for flight 
attendants could impede flight attendant performance during emergency 
evacuations or during routine safety duties requiring a high degree of 
alertness. Cost savings could result from improved worker productivity; 
however, no information is available to quantify this benefit.
    The change in duty hours coupled with adequate rest could decrease 
absenteeism and improve health. However, the information needed to 
quantify this, is not currently available.
    In addition, the FAA is concerned with passenger and crewmember 
safety, and is sensitive to crewmember health and welfare. The FAA 
recognizes that employee health could improve if employees get more 
rest.
Costs
    Cost estimates contained in this summary are based on 1993 dollars 
and are discounted at an annual effective rate of 7 percent. The FAA 
estimates that the cost to the air carrier industry of establishing 
flight attendant duty period limitations and rest requirements will be 
$42.7 million over a 15-year period. The FAA expects that operators 
would incur costs in the areas of recordkeeping and additional 
staffing.
    Cost estimates for supplemental air carriers and scheduled major, 
national, and regional/commuter operators are separated. The FAA 
estimates that the nondiscounted cost for all supplemental air carriers 
for the first year will be approximately $2.5 million, and the annual 
nondiscounted cost for all supplemental carriers would be approximately 
$2.23 million. The FAA estimates that the total discounted costs for 
supplemental air carriers over 15 years will be approximately $20.8 
million. The FAA estimates that the first-year nondiscounted cost for 
scheduled major, national, and regional/commuter operators will be 
approximately $2.9 million, and the annual nondiscounted cost for these 
operators would be approximately $1.2 million. The FAA estimates that 
the total discounted costs for scheduled major, national, and regional/
commuter over 15 years will be approximately $21.9 million. Therefore, 
over 15 years, the discounted cost for the air carrier industry will be 
$42.7 million.
    The above cost estimate is based on the assumption that air 
carriers must augment their flight attendant crews. In some situations, 
augmentation under the flight attendant rule requirements may be 
avoided if an air carrier adopts and applies to flight attendants, by 
option, the international, supplemental carrier pilot rules covering 
flight and duty period.
Twenty-Four Consecutive-Hour Rest Period During any Seven Consecutive 
Days
    Southwest Airlines stated that the requirement for 24 consecutive 
hours of rest during any 7 consecutive days would make it necessary for 
the air carrier with which the commenter is affiliated to hire about 
100 additional flight attendants at a first-year cost of $710,000 and a 
subsequent annual cost of $600,000. A commenter representing Transport 
Workers Union of America on behalf of Southwest Airlines flight 
attendants indicated that the proposed rule, if adopted, would create a 
financial burden for flight attendants and their employers and would 
result in an average annual loss of $11,063 in extra income for each 
flight attendant. This loss, projected for 2,200 flight attendants for 
1 year, would total $24 million in lost income.
FAA Response
    The requirement for 24 consecutive hours of rest in any 7 
consecutive days is designed to supplement daily rest requirements and 
to ensure that flight attendants receive the opportunity for adequate 
rest. The FAA did not verify lost flight attendant income, because the 
annual loss of extra income to some flight attendants represents a gain 
to flight attendants who would be hired. This income transfer is not 
considered a cost of this rulemaking.
Single Set of Duty Time Rules for Cabin and Flight Crew Members
    Great American Airways stated that the total cost savings derived 
from implementing a single set of duty time rules for its cabin and 
flight crewmembers, as opposed to adopting the rules proposed in the 
NPRM, would exceed $100,000 per year.
FAA Response
    The FAA recognizes that giving operators the option to apply flight 
crewmember flights, duty, and rest requirements to flight attendants 
may provide a cost savings to certain operators, particularly 
supplemental operators. The FAA expects that the operators that choose 
the option will incur costs that are lower than those estimated in the 
final regulatory evaluation.
    However, the FAA recognizes that operators who choose to apply the 
flight crewmember regulations for duty limitations and rest 
requirements must submit an application to the appropriate Flight 
Standards District Office for approval. This is a minor, one-time cost, 
and the FAA assumes that operators who choose to incur this cost would 
do so because it would obviate those operators from designing and 
establishing a tracking system for flight attendants. Instead, this 
option would allow them to use whatever system is in place for flight 
crewmembers. The application process chosen was selected deliberately 
out of concern that recordkeeping costs be kept to a minimum. That is, 
the FAA chose an application process that is very familiar to carriers, 
the commonly-used procedure for changes to operations specifications.
Limiting Scheduled Duty Period to Fourteen Hours
    Great American Airways stated that limiting scheduled flight 
attendant duty periods to 14 hours would force the air carrier and 
other supplemental air carriers to add flight attendants at 
intermediate stops. The commenter stated that, because company-required 
deadhead transportation would be considered part of a duty period under 
the FAA's proposal, it would be necessary to schedule flight attendants 
for required rest after they completed a deadhead flight segment and 
before they began the next duty period.
    This commenter also stated that the proposed rules would impose 
substantially greater costs on supplemental air carriers than other air 
carriers because supplemental air carriers rarely have travel 
privileges with scheduled carriers, and, when they do, they are often 
very restrictive. Finally, this commenter stated that unanticipated 
schedule and routing changes occur more frequently among charter 
operators than scheduled carriers and could severely curtail the 
flexibility of supplemental air carriers.
FAA Response
    The FAA agrees that the greatest costs will be incurred by air 
carriers that schedule flight attendants for the longest duty periods. 
However, the commenter does not appear to provide any information on 
the air carrier's ability to augment existing crews. The FAA points out 
that costs could be minimized by using crew argumentation as a means of 
compliance. In addition, time spent in deadhead transportation is not 
considered part of a duty period; therefore, an operator is not 
required to provide a rest period for flight attendants following time 
spent in deadhead transportation.
Overall Costs
    ATA stated that the FAA has understated costs considerably. This 
commenter stated that the annual cost of complying with the proposed 
regulation would be at least $8.0 million. This cost would include 
programming expenses, additional personnel costs, costs associated with 
extended layovers, and costs associated with reserve scheduling 
(assuming that carrier reserve scheduling practices are not modified). 
Assuming a discount rate of 7.0 percent and an inflation rate of 3.0 
percent, the 15-year present value cost for the association's members 
would be approximately $88.9 million.
FAA Response
    The survey of ATA members indicates that the annual cost would be 
at least $8.0 million. ATA stated that added annual personnel costs for 
air carrier operators would be $4.0 million, additional meal/hotel 
expenses would be $1.5 million, and additional reserve staffing would 
be $2.5 million. Finally, ATA stated that carriers can expect to incur 
a one-time expense of between $2.0 million and $3.0 million for 
computer system program modifications. After contracting ATA twice 
after the comment period closed to obtain clarifying information, the 
FAA concluded that their estimate could not be used in its entirety 
because information such as the number of affected carriers, wage 
rates, additional employees needed, or hours worked was not provided.
    In addition, ATA did not provide information on the cost of 
augmenting the existing crew. The FAA permits longer duty periods with 
the use of augmented crews. FAA data indicates that many flights are 
staffed with more than the minimum flight attendant crew complement; 
therefore, little or no additional cost would be incurred to meet the 
crew argumentation requirements.
    ATA also stated that the 15-year present value cost for its members 
would be $88.9 million. This estimate assumed a discount rate of 7.0 
percent and an inflation rate of 3.0 percent. The basis for the 
commenter's estimate of the annual cost ($8.0 million) was not detailed 
enough for the FAA to use it or the 15-year estimate derived from it.
    The FAA has nevertheless attempted to develop an industry cost 
estimate by recalculating the ATA estimate to exclude the ATA inflation 
factor and by accounting for the fact that ATA members only represent a 
portion of the industry that would be affected. As shown in the 
Regulatory Evaluation, that figure would be $78.8 million. However, the 
original information provided could not be fully substantiated, which 
suggests that the ATA estimate may not be representative of the total 
industry.
Supplemental Carriers
    The Coalition stated that the median flight attendant salary at 
supplemental air carriers is $18,461. The commenter indicated that this 
estimate may be high because it represents the average salary at 
supplemental carriers that have a collective bargaining agreement with 
their flight attendant workforce. The commenter also stated that the 
FAA assumed that the rule would lead to the hiring of 6,000 flight 
attendants at supplemental carriers, and that the additional cost for 
these new hires would be $1,107,600. The FAA received revised salary 
information from the commenter stating that the average salary of a 
flight attendant working for a supplemental carrier is $24,552, which 
includes $6,092 in benefits.
FAA Response
    The final regulatory evaluation assumes that, in the case of 
supplemental operators, each flight attendant works 150 duty periods, 
and that a carrier's cost per duty period is $163.68. Therefore, the 
cost of 6,000 additional duty periods would be $982,100. To the extent 
practicable, this cost estimate for supplemental operations was used in 
developing the final regulatory evaluation.
Irregular Operations
    Delta Air Lines stated that the proposed rule would cause the air 
carrier to incur costs associated with irregular operations. The air 
carrier estimated that it would have to hire 36 flight attendants at an 
annual salary cost of $1.3 million for irregular operations. Other 
costs associated with hiring additional flight attendants to meet the 
requirements of the proposed rule, if adopted, would total $2.86 
million in the initial year. The recurring annual cost of the proposed 
rule, if adopted, would be nearly $2.5 million.
    This commenter stated that, based on operations in June/July 1992 
and January/February 1993, 62 flight attendants working together did 
not meet the requirements of the NPRM and would require crew 
replacement. The commenter typically schedules flight attendants for 3-
day city pairings with an average flight attendant crew of six. Because 
most of the replacements that were needed were on domestic flights, the 
commenter used an average of four flight attendants. These results 
showed that 744 additional duty days would be required. The commenter 
calculated that an additional 36 flight attendants would be needed 
because a reserve flight attendant is available to fly an average of 
20.5 days per month. Given an average monthly salary of almost $2,500, 
plus monthly hotel, meal, and transportation expenses of almost $650 
for irregular operations, the cost for a flight attendant would be 
about $3,100 per month, or $1.3 million annually.
    The commenter also stated that they do not have a deplaning period. 
That is, pay and expenses cease at the block-in time of the last flight 
in the duty period for the trip. This commenter calculates that the 
cost of a 15-minute deplaning period would result in the hiring of 20 
additional flight attendants. The cost would amount to $749,000 
annually.
    Finally, the commenter provided information documenting the 
carrier's one-time cost of computer software changes, including 
recordkeeping. The only additional information is that the cost of 
programming and testing per man-hour is $40.
FAA Response
    The FAA received clarification from the commenter stating that ``An 
Ad Hoc Computer Program was developed to search through our crew 
tracking systems to identify irregular operations that had occurred 
that would have required crew replacement under the NPRM.'' The 
commenter also stated that the NPRM ``Would require crew replacement.'' 
Finally, the commenter stated that they used an average crew of four 
flight attendants in their calculations, which implies that they were 
replacing their existing crew. This leads the FAA to assume that the 
commenter did not consider crew augmentation. However, the FAA did use 
some of the salary and cost data provided by the commenter.
    With regard to hiring additional flight attendants for a 15-minute 
deplaning period, the FAA notes that there is no new requirement in 
this rule concerning deplaning; deplaning of the aircraft is a current 
requirement.
Small Operators
    Sun Country Airlines operates a fleet of 10 aircraft with 520 
employees, 170 of whom are flight attendants. Based on 1992 operations, 
the proposed rule would have required the commenter to hire 34 
additional flight attendants, which would have increased operating 
costs (i.e., salaries, benefits, costs of training, hotels, meals, 
deadhead travel, and general administrative overhead) by $2.6 million 
in 1992. However, this air carrier stated that, by applying crewmember 
flight, duty, and rest requirements to flight attendants, the air 
carrier would need to employ 20 additional flight attendants rather 
than 34 additional flight attendants, with increased operating costs of 
$1.75 million rather than $2.6 million. However, these lower costs 
still exceeded the entire 1992 new profit for this carrier.
    The Regional Airline Association stated that the proposed rule 
would either require an additional jump seat in the cabin for which 
there is insufficient space or it would require that a passenger seat 
be set aside for the additional flight attendant. This commenter stated 
that daily or routine loss of a revenue seat on a fleet of regional 
aircraft with 20 to 50 seats would be enormous. It also pointed out the 
added costs associated of layover lodging, meals, and per diem, and the 
significant incremental weight of an added crewmember.
    The National Air Carrier Association stated that the proposed rule 
would impose costs of approximately $372,000 in additional flight 
attendant staffing, and approximately $50,000 in recordkeeping.
FAA Response
    The FAA received additional clarification from Sun Country 
indicating that the proposed rule would cost $2.6 million. The annual 
cost to deadhead flight attendants to their domicile would be $832,000. 
In addition, hotel accommodations would be $842,000, added per diem 
cost would be $308,000, initial and recurrent training would be 
$10,200, and administrative costs would be $58,000. Because this 
commenter does not have any interline agreements, it would have to pay 
the added costs for deadhead tickets. This commenter estimated that 
these costs would be $579,000.
    Based upon this cost estimate, the cost per added flight attendant 
would be about $76,500 per flight attendant ($2.6 million divided by 34 
additional flight attendants). If this commenter did not have to incur 
the costs for deadhead tickets, then the added cost would be $60,300 
per flight attendant.
    The commenter also provided information stating that the annual 
cost of applying the part 121 supplemental carrier pilot flight, duty, 
and rest requirements to flight attendants would be $1.75 million. The 
added cost of 20 flight attendants would be $489,000. Hotel expenses 
would be $679,000; per diem costs would be $244,000; training would 
cost $6,000; and administrative costs would be $34,000. Finally, the 
annual cost of deadheading flight attendants back to their place of 
domicile would be $289,000.
    Based upon their total cost estimate, the cost per added flight 
attendant would be $1.75 million divided by 20 additional flight 
attendants, or about $87,000 per flight attendant. If this commenter 
did not have to incur the costs for deadhead tickets, then the added 
cost would be $72,600 per flight attendant.
    The FAA contends that these cost estimates represent the costs 
associated with replacing the existing crew. The cost estimates do not 
appear to represent the costs associated with augmenting the existing 
crew with additional flight attendants. An air carrier whose goal is 
profit maximization and cost minimization would choose the least costly 
means of achieving compliance with the proposed rule, and, in most 
cases, that appears to be the crew augmentation option.
    RAA asserted that the final rule would impose costs based on the 
fact that some aircraft would fly longer than 14 hours and full. The 
FAA contacted this commenter and asked a clarifying question on the 
number of times that an aircraft would fly more than 14 hours full. The 
commenter was unable to provide information to substantiate this 
assertion, and therefore, while a problem may exist, the FAA is unable 
to determine the magnitude of it.
    The FAA received additional information from a NACA member 
(American Trans Air) stating that, to calculate annual costs, they 
multiplied the average number of block hours in the fleet by the 
percentage of flight hours the NPRM is expected to affect. The product 
is the total number of affected block hours.
    The number of affected block hours was then divided by the expected 
number of flight attendant utilization hours, which varies by aircraft 
type, and multiplied by the number of flight attendants to compute crew 
requirements. Based on this calculation, 20 additional flight 
attendants would be needed to meet the requirements of the proposed 
rule. This commenter then multiplied the number of additional flight 
attendants by their annual salary, including fringe benefits and 
training, to arrive at a cost estimate of $372,000. Administrative 
costs of $80,000 were added.
    The FAA received additional clarification that the percentage of 
flight hours was based upon the commenter's examination of all flights 
that exceeded 14 hours. The commenter did not look at flights of 14 to 
16 hours, 16 to 18 hours, or 18 to 20 hours.
    The commenter divided the number of affected block hours by the 
expected flight attendant utilization hours (Boeing 727, 60 hours; 
Boeing 757 and Lockheed L-1011, 56 hours). The commenter did not know 
how many duty periods this represented. After multiplying this number 
by the number of flight attendants needed to complete crew 
requirements, the commenter concluded that 20 additional flight 
attendants would be needed to augment its flights.
    The $13,000 annual salary represents a flight attendant's first-
year salary without overtime. The 20 percent benefits estimate 
represents the company's portion of employee benefits.
    To the extent practicable, the cost information provided by 
commenters was used to revise the cost estimates in the final 
regulatory evaluation.
Recordkeeping Costs
    Several commenters provided the FAA with information on 
recordkeeping. The Air Transport Association estimated that air 
carriers would incur a one-time expense for computer system program 
modifications of $2.0 million to $3.0 million. Delta Air Lines stated 
that the one-time cost of software computer changes, including 
recordkeeping, would be $367,200. American Trans Air, a member of the 
National Air Carrier Association, stated that administrative costs 
would be $80,000, approximately $54,000 of which would be the cost to 
program and upgrade software, and $26,000 of which would be the cost of 
data entry and associated labor.
FAA Response
    Because of limited supporting documentation, a wide variation 
between commenters' estimates, and the difficulty of ascertaining what 
portion of the recordkeeping costs could be attributed to the 
implementation of this final rule versus the cost to upgrade current 
systems, the FAA stands by its original recordkeeping cost estimate.

Summary of Benefits and Costs

    The FAA estimates that the cost of compliance with the requirements 
of this final rule will be $42.7 million, discounted.
    Although benefits cannot be quantified, the FAA concludes that the 
establishment of flight attendant duty period limitations and rest 
requirements are warranted, because they will contribute to an overall 
enhancement of transport category airplane safety and utility that will 
both promote and enhance the U.S. air transportation system.

Final Regulatory Flexibility Determination

    The Regulatory Flexibility Act of 1980 (RFA was enacted by Congress 
to ensure that small entities are not unnecessarily and 
disproportionately burdened by Federal regulations. The RFA requires a 
Regulatory Flexibility Analysis if a proposed rule would have ``a 
significant economic impact on a substantial number of small 
entities.'' FAA Order 2100.14A outlines FAA's procedures and criteria 
for implementing the RFA.
    The fleet size for an operator of aircraft for hire to be 
considered a small entity is nine or fewer aircraft. The threshold 
annualized cost levels for operators of aircraft for hire in 1993 
dollars are $117,800 for scheduled operators whose fleets have aircraft 
with seating capacities of more than 60, $67,000 for scheduled 
operators whose fleets have aircraft with seating capacities of 60 or 
less (other scheduled operators), and $4,570 for unscheduled operators. 
The proposals in the NPRM would affect air carriers that provide 
passenger-carrying operations in aircraft for which flight attendants 
are required. Other types of aviation companies would not be affected. 
A ``substantial number'' of small entities is a number that is not less 
than 11 and that is more than one-third of the small entities subject 
to this rule.
    According to FAA records of small entity air carriers that provide 
passenger-carrying operations in aircraft that require flight 
attendants, there are 23 part 125 and 135 operators that could be 
affected by the final rule. Of these 23 operators, 7 are part 121/135 
operators, 12 are part 125 operators, and 4 are part 135 operators. The 
affected operators are those with nine or fewer aircraft. At least one 
of the aircraft that they own have a seating configuration of more than 
19 as described in either Sec. 125.269 or Sec. 135.107 and therefore 
would have at least one flight attendant on board. There are also 8 
part 121 operators that would be affected by the final rule. In July 
1993, there were a total of 25 part 121/135 operators, 39 part 125 
operators, and 3,040 part 135 operators. There are also more than 100 
part 121 operators. The number of carriers that could be affected by 
the rule does not exceed one-third of the total number of carriers in 
any of the four categories of operators (parts 121, 121/125, 125 and 
135). The FAA has therefore determined that a regulatory flexibility 
analysis is not necessary.

International Trade Impact Statement

    This final rule would not constitute a barrier to international 
trade, including the export of American goods and services to foreign 
countries and the import of foreign goods and services into the United 
States.
    The FAA has determined that the amendments to parts 121 and 135 
will not have a significant impact on international trade. The final 
rule is not expected to have an impact on trade opportunities for U.S. 
firms doing business overseas or foreign firms doing business in the 
United States. This finding is based in large part upon the review of 
foreign civil aviation regulations governing flight attendant flight 
and duty time practices and minimum rest requirements found in the 
Industry Study as well as information supplied by commenters to the 
public docket.
    The Industry Study review shows that 23 countries, including 
Argentina, Belgium, Brazil, Denmark, the Netherlands, France, Norway, 
Portugal, Sweden, Switzerland, and West Germany, have government 
regulations on flight attendant flight and duty times and rest periods.
    The comment provided by the Flight Attendants states that the 
European Community, through its Joint Aviation Authority (JAA) ``is 
poised to issue flight attendant duty time and rest provisions which 
would be based on state of the art research concerning work schedules 
and fatigue.'' They state that the JAA rule would base duty time and 
rest limits on the time of departure and the number of segments flown.
    On the other hand, the Industry Study noted that 24 countries, 
including Australia, Canada, Greece, Ireland, Italy, Japan, and Mexico, 
do not regulate flight attendant work time.
    The FAA concludes that there are many countries with flight 
attendant flight and duty times and rest periods and many countries 
without these regulations. Second, many firms in the United States 
appear to be already in compliance or near compliance with the final 
regulation. Therefore, the FAA has determined that the amendments to 
parts 121, 125, and 135, will not have a significant impact on 
international trade.

Federalism Implications

    The regulation herein will not have substantial direct effects on 
the states, on the relationship between the national government and the 
states, or on the distribution of power and responsibilities among the 
various levels of government. Therefore, in accordance with Executive 
Order 12612, it is determined that this regulation will not have 
sufficient federalism implications to warrant the preparation of a 
Federalism Assessment.

Conclusion

    For the reasons discussed in the preamble, the FAA has determined 
that this regulation is a significant regulatory action under Executive 
Order 12866. In addition, the rule is considered significant under DOT 
Regulatory Policies and Procedures. However, the FAA has determined 
that this regulation will not have a significant economic impact, 
positive or negative, on a substantial number of small entities or on 
international trade. A final regulatory evaluation of the regulation, 
including a final Regulatory Flexibility Determination and 
International Trade Impact Analysis, has been placed in the docket. A

the domestic, flag, or supplemental air carrier or commercial operator. 
The time is calculated using either Coordinated Universal Time or local 
time to reflect the total elapsed time.
    Flight attendant means an individual, other than a flight 
crewmember, who is assigned by a domestic, flag, or supplemental air 
carrier or commercial operator, in accordance with the required minimum 
crew complement under the certificate holder's operations 
specifications or in addition to that minimum complement, to duty in an 
aircraft during flight time and whose duties include but are not 
necessarily limited to cabin-safety-related responsibilities.
    Rest period means the period free of all restraint or duty for a 
domestic, flag, or supplemental air carrier or commercial operator and 
free of all responsibility for work or duty should the occasion arise.
    (b) Except as provided in paragraph (c) of this section, a 
domestic, flag, or supplemental air carrier or commercial operator may 
assign a duty period to a flight attendant only when the applicable 
duty period limitations and rest requirements of this paragraph are 
met.

flight attendant scheduled to a duty period of 14 hours or less as 
provided under paragraph (b)(1) of this section must be given a 
scheduled rest period of at least 9 consecutive hours. This rest period 
must occur between the completion of the scheduled duty period and the 
commencement of the subsequent duty period.
    (3) The rest period required under paragraph (b)(2) of this section 
may be scheduled or reduced to 8 consecutive hours if the flight 
attendant is provided a subsequent rest period of at least 10 
consecutive hours; this subsequent rest period must be scheduled to 
begin no later than 24 hours after the beginning of the reduced rest 
period and must occur between the completion of the scheduled duty 
period and the commencement of the subsequent duty period.
    (4) A domestic, flag, or supplemental air carrier or commercial 
operator may assign a flight attendant to a scheduled duty period of 
more than 14 hours, but no more than 16 hours, if the air carrier or 
commercial operator has assigned to the flight or flights in that duty 
period at least one flight attendant in addition to the minimum flight 
attendant complement required for the flight or flights in that duty 
period under the air carrier's or the commercial operator's operations 
specifications.
    (5) A domestic, flag, or supplemental air carrier or commercial 
operator may assign a flight attendant to a scheduled duty period of 
more than 16 hours, but no more than 18 hours, if the air carrier or 
commercial operator has assigned to the flight or flights in that duty 
period at least two flight attendants in addition to the minimum flight 
attendant complement required for the flight or flights in that duty 
period under the air carrier's or the commercial operator's operations 
specifications.
    (6) A domestic, flag, or supplemental air carrier or commercial 
operator may assign a flight attendant to a scheduled duty period of 
more than 18 hours, but no more than 20 hours, if the scheduled duty 
period includes one or more flights that land or take off outside the 
48 contiguous states and the District of Columbia, and if the air 
carrier or commercial operator has assigned to the flight or flights in 
that duty period at least three flight attendants in addition to the 
minimum flight attendant complement required for the flight or flights 
in that duty period under the domestic air carrier's or the commercial 
operator's operations specifications.
    (7) Except as provided in paragraph (b)(8) of this section, a 
flight attendant scheduled to a duty period of more than 14 hours but 
no more than 20 hours, as provided in paragraphs (b)(4), (b)(5), and

may be scheduled or reduced to 10 consecutive hours if the flight 
attendant is provided a subsequent rest period of at least 14 
consecutive hours; this subsequent rest period must be scheduled to 
begin no later than 24 hours after the beginning of the reduced rest 
period and must occur between the completion of the scheduled duty 
period and the commencement of the subsequent duty period.
    (9) Notwithstanding paragraphs (b)(4), (b)(5), and (b)(6) of this 
section, if a domestic, flag, or supplemental air carrier or commercial 
operator elects to reduce the rest period to 10 hours as authorized by 
paragraph (b)(8) of this section, the air carrier or commercial 
operator may not schedule a flight attendant for a duty period of more 
than 14 hours during the 24-hour period commencing after the beginning 
of the reduced rest period.
    (10) No domestic, flag, or supplemental air carrier or commercial 
operator may assign a flight attendant any duty period with the air 
carrier or commercial operator unless the flight attendant has had at 
least the minimum rest required under this section.
    (11) No domestic, flag, or supplemental air carrier or commercial 
operator may assign a flight attendant to perform any duty with the air 
carrier or operator during any required rest period.
    (12) Time spent in transportation, not local in character, that a 
domestic, flag, or supplemental air carrier or commercial operator 
requires of a flight attendant and provides to transport the flight 
attendant to an airport at which that flight attendant is to serve on a 
flight as a crewmember, or from an airport at which the flight 
attendant was relieved from duty to return to the flight attendant's 
home station, is not considered part of a rest period.
    (13) Each domestic, flag, or supplemental air carrier must relieve 
each flight attendant engaged in air transportation and each commercial 
operator must relieve each flight attendant engaged in air commerce 
from all further duty for at least 24 consecutive hours during any 7 
consecutive calendar days.
    (14) A flight attendant is not considered to be scheduled for duty 
in excess of duty period limitations if the flights to which the flight 
attendant is assigned are scheduled and normally terminate within the 
limitations but due to circumstances beyond the control of the 
domestic, flag, or supplemental air carrier or commercial operator 
(such as adverse weather conditions) are not at the time of departure 
expected to reach their destination within the scheduled time.
    (c) Notwithstanding paragraph (b) of this section, a domestic, 
flag, or supplemental air carrier or commercial operator may apply the 
flight crewmember flight time and duty limitations and rest 
requirements of this part to flight attendants for all operations 
conducted under this part provided that--
    (1) The certificate holder establishes written procedures that--
    (i) Apply to all flight attendants used in the certificate holder's 
operation;
    (ii) Include the flight crewmember requirements contained in 
subparts Q, R, or S of this part, as appropriate to the operation being 
conducted, except that rest facilities on board the aircraft are not 
required;
    (iii) Include provisions to add one flight attendant to the minimum 
flight attendant complement for each flight crewmember who is in excess 
of the minimum number required in the aircraft type certificate data 
sheet and who is assigned to the aircraft under the provisions of 
subparts Q, R, and S, as applicable, of this part;
    (iv) Are approved by the Administrator and are described or 
referenced in the certificate holder's operations specifications; and
    (2) Whenever the Administrator finds that revisions are necessary 
for the continued adequacy of the written procedures that are required 
by paragraph (c)(1) of this section and that had been granted final 
approval, the certificate holder must, after notification by the 
Administrator, make any changes in the procedures that are found 
necessary by the Administrator. Within 30 days after the certificate 
holder receives such notice, it may file a petition to reconsider the 
notice with the FAA Flight Standards District Office that is charged 
with the overall inspection of the certificate holder's operations. The 
filing of a petition to reconsider stays the notice, pending decision 
by the Administrator. However, if the Administrator finds that an 
emergency requires immediate action in the interest of safety, the 
Administrator may, upon a statement of the reasons, require a change 
effective without stay.
