NATIONAL TRANSPORTATION SAFETY BOARD

49 CFR Part 830


Notification and Reporting of Aircraft Accidents or Incidents and 
Overdue Aircraft, and Preservation of Aircraft Wreckage, Mail, Cargo, 
and Records

AGENCY: National Transportation Safety Board (NTSB).

ACTION: Final rule.

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

SUMMARY: The NTSB is amending its regulations concerning notification 
and reporting requirements regarding aircraft accidents or incidents. 
In particular, the NTSB is adding regulations to require operators to 
report certain incidents to the NTSB. The NTSB is also amending 
existing regulations to provide clarity and ensure that the appropriate 
means for notifying the NTSB of a reportable incident is listed 
correctly in the regulation.

[[Page 923]]


DATES: The revisions and additions published in this final rule will 
become effective March 8, 2010.

ADDRESSES: A copy of the notice of proposed rulemaking (NPRM), 
published in the Federal Register (FR), is available for inspection and 
copying in the NTSB's public reading room, located at 490 L'Enfant 
Plaza, SW., Washington, DC 20594-2000. Alternatively, a copy of the 
NPRM is available on the government-wide Web site on regulations at 
http://www.regulations.gov.

SUPPLEMENTARY INFORMATION: 

Regulatory History

    On October 7, 2008, the NTSB published an NPRM titled 
``Notification and Reporting of Aircraft Accidents or Incidents and 
Overdue Aircraft, and Preservation of Aircraft Wreckage, Mail, Cargo, 
and Records'' in 73 FR 58520. This NPRM proposed and the final rule 
herein codifies the addition of five reportable incidents, the 
reporting of which the NTSB believes will improve aviation safety. In 
particular, the new subsections within 49 CFR 830.5(a) will require 
operators to report the following: failure of any internal turbine 
engine component that results in the escape of debris other than out 
the exhaust path; release of all or a portion of a propeller blade from 
an aircraft, excluding release caused solely by ground contact; a 
complete loss of information, excluding flickering, from more than 50 
percent of an aircraft's cockpit displays, known as Electronic Flight 
Instrument System displays, Engine Indication and Crew Alerting System 
displays, Electronic Centralized Aircraft Monitor displays, or other 
such displays; Airborne Collision Avoidance System (ACAS) resolution 
advisories issued either (1) when an aircraft is being operated on an 
instrument flight rules (IFR) flight plan and compliance with the 
advisory is necessary to avert a substantial risk of collision between 
two or more aircraft, or (2) to an aircraft operating in class A 
airspace; damage to helicopter tail or main rotor blades, including 
ground damage, that requires major repair or replacement of the 
blade(s); and any event in which an aircraft operated by an air carrier 
lands or departs on a taxiway, incorrect runway, or other area not 
designed as a runway, or experiences a runway incursion that requires 
the operator or the crew of another aircraft or vehicle to take 
immediate corrective action to avoid a collision. The NPRM also 
proposed certain wording changes to other existing subsections within 
49 CFR 830.5(a) for clarity and proposed a change in the footnote that 
provides the locations of NTSB regional offices.
    The NTSB notes that it further analyzed the potential application 
of the Regulatory Flexibility Act, as published in Title 5 United 
States Code (U.S.C.), sections 601-612, to this rule. Prior to 
publishing the NPRM, the NTSB considered whether this rule would have a 
significant economic impact on a substantial number of small entities 
and certified under 5 U.S.C. 605(b) that this rule would not have such 
an impact. The NTSB verifies this assessment and notes that while this 
rule will require some affected individuals to complete NTSB Form 
6120.1, ``Pilot/Operator Accident/Incident Report,'' the cost to 
complete this form is nominal. Therefore, the NTSB verifies that its 
certification under 5 U.S.C. 605(b) was valid.
    In response to the publication of this NPRM, the NTSB received and 
carefully considered six comments. The NTSB did not receive any 
requests for a public meeting; therefore, the NTSB did not hold a 
public meeting on the NPRM. Below is a summary of and response to each 
concern that commenters raised, arranged by issue.
Discussion of Comments and Changes
    In the interest of ensuring that the provisions of 49 CFR 830.5 are 
complete, comprehensible, and enforceable, the NTSB's final rule herein 
includes revisions to three new subsections of 49 CFR 830.5 that the 
NTSB proposed, including subsections (a)(9), (a)(10), and (a)(12), 
which proposed requiring reports of a complete loss of information from 
certain electronic displays, certain types of resolution advisories, 
and certain runway incursions, respectively. These changes are 
described in the sections below.

Proposed Revision to Section 830.5(a)(3)

    The NPRM proposed to amend 49 CFR 830.5(a)(3) to require 
notification of incidents in which ``[f]ailure of any internal turbine 
engine component that results in the escape of debris other than out 
the exhaust path'' occurs. The NTSB received two comments on this 
proposed addition.
    One commenter, an aviation industry manufacturing association, 
objected to the requirement that the NTSB be notified immediately for 
the following proposed events: Failure of any internal turbine engine 
component that results in the escape of the debris other than out the 
exhaust path and release of all or a portion of a propeller blade from 
an aircraft, excluding release caused solely by ground contact. The 
commenter stated that, in accordance with 14 CFR 21.3(c), operators are 
already required to report such failures to the Federal Aviation 
Administration (FAA). The commenter further stated that the requirement 
to report these events to the NTSB would put an additional burden on 
the operator by requiring duplicate reporting of events. The commenter 
suggested the development of a joint FAA/NTSB reporting system that 
would alert both agencies concurrently when one of the reportable 
events occurs.
    The NTSB disagrees with these comments. The NTSB is aware that 14 
CFR 21.3 requires holders of type certificates, supplemental type 
certificates, and parts manufacturing approval to notify the FAA within 
24 hours, or the next business day on weekends or holidays, of an 
engine or component failure. But the NTSB also notes that 14 CFR 
21.3(d)(1)(iii) states that a report to the FAA is not required if the 
event has been reported to the NTSB. The NTSB needs immediate 
notification of a reportable event to determine the appropriate level 
of response, which might include immediately dispatching an 
investigator to the scene. The NTSB continues to believe that utilizing 
the 14 CFR 21.3 notification system alone that initially reports 
failures to the FAA presents an unacceptable delay in the notification 
to the NTSB and the initiation of a response. The NTSB reiterates that 
it has investigated catastrophic engine failures after being belatedly 
notified, and critical evidence was lost as a result of the delay in 
notification, thus hampering the investigation. The NTSB also notes 
that 49 CFR 830.10 requires the operator of an aircraft involved in a 
reportable event to preserve the wreckage and all pertinent records 
until the NTSB takes custody or until the wreckage and records have 
been released pursuant to 49 CFR 831.12. The NTSB believes that relying 
on 14 CFR 21.3 reports that would initially be sent to the FAA would 
delay not only the NTSB's response to the event but also the return of 
custody of the airplane and/or engine to the operator, thus delaying 
their repair and return to service. The NTSB is aware that 14 CFR 
121.703 and 135.415 require those respective Part 121 or 135 
certificate holders to notify their FAA certificate-holding district 
offices of an engine failure within 24 hours, or the next business day 
on weekends or holidays. While engine or component failures are

[[Page 924]]

relatively rare, the NTSB is not concerned with every engine or 
component failure that occurs; therefore, this rule will not materially 
affect operators. However, the NTSB is very concerned about engine 
failures that result in debris coming out of the engine through a path 
other than the exhaust, also referred to as uncontained engine 
failures. These failures can and have liberated debris, resulting in 
damage to the airplane or its systems and/or injured passengers. 
Fortunately, these types of reportable events are very rare. Thus, the 
NTSB does not expect that it will be unduly burdensome for Part 121 and 
135 operators who experience engine failures resulting in debris 
exiting the engine through a path other than the exhaust or one of the 
other previously reportable events to make the dual notification to 
their FAA certificate-holding district offices as well as the NTSB.
    The commenter also suggested that a system be developed so that the 
FAA-required 14 CFR 21.3 data would be shared concurrently with the 
NTSB. While the NTSB appreciates the commenter's suggestion, the NTSB 
believes that situations could occur in which the notification that the 
NTSB receives would be delayed, such as occurrences under 14 CFR 21.3 
in which notification occurs within 24 hours, or the next business day 
if the event occurred on the weekend or a holiday.
    One commenter, a professional pilots' union, fully concurred with 
the proposed rule requiring the NTSB to be notified immediately of an 
event where debris exited an engine through some other path besides the 
engine's exhaust. The NTSB appreciates the commenter's support on this 
proposed immediate notification requirement.
    In summary, the NTSB understands that this new rule will require 
Part 121 and 135 operators who, in accordance with 14 CFR 121.703 and 
135.415, respectively, must report any engine or component malfunctions 
or failures to both their FAA certificate-holding district offices and 
the NTSB. The NTSB continues to believe, however, that the language of 
the reporting requirement will result in timely notification of 
incidents in which a failure of an internal engine component resulted 
in the escape of debris from an exit other than out the exhaust path. 
Therefore, the NTSB has not amended this addition.

Proposed Addition of Section 830.5(a)(8)

    The NPRM proposed to add section 830.5(a)(8) to 49 CFR Part 830 to 
require the reporting of any ``release of all or a portion of a 
propeller blade from an aircraft, excluding release caused solely by 
ground contact.'' One commenter, a professional pilots' union, 
dissented with the NTSB regarding the exclusion of a structural failure 
of a propeller or portion of a propeller caused solely by ground 
contact. The NTSB disagrees with the commenter's position that the NTSB 
should broaden the section to include all incidents in which propeller 
blades or blade sections have separated from an aircraft. The commenter 
stated that liberated propeller blades or blade segments pose a 
significant hazard to the crew, passengers, and bystanders.
    The NTSB agrees with the commenter regarding the hazards that 
liberated propeller blades or segments of propeller blades pose to 
crews, passengers, and bystanders. However, the NTSB notes that 
propeller blades are designed and certified to operate within the 
atmosphere and, as such, the expectation is that they remain intact and 
in place during normal operation. Propeller blades are not designed or 
expected to continue to remain intact and in place following contact 
with the ground. The NTSB continues to believe that the language of the 
reporting requirement will achieve the NTSB's objective of receiving 
notification of any release of all or a portion of a propeller blade 
from an aircraft, inconsistent with its design parameters and 
certification, thus excluding releases caused solely by ground contact. 
Therefore, the NTSB has not amended this addition.

Proposed Addition of Section 830.5(a)(9)

    The NPRM proposed to add section 830.5(a)(9) to 49 CFR Part 830 to 
require the reporting of ``[a] complete loss of information, excluding 
flickering, from more than 50 percent of an aircraft's certified 
electronic primary displays.'' The NTSB has carefully reviewed the 
comments received concerning this section and has concluded that the 
language should be amended to require notification of ``[a] complete 
loss of information, excluding flickering, from more than 50 percent of 
an aircraft's cockpit displays known as: (A) Electronic Flight 
Instrument System (EFIS) displays; (B) Engine Indication and Crew 
Alerting System (EICAS) displays; (C) Electronic Centralized Aircraft 
Monitor (ECAM) displays; or (D) Other displays of this type, which 
generally include a primary flight display (PFD), primary navigation 
display (PND), and other integrated displays.''
    The NTSB now recognizes the need to revise the proposed language to 
avoid capturing an excessive number of failures. For example, under the 
proposed language, a failed electronic exhaust gas temperature (EGT) 
gauge that is the only means of monitoring EGT would have been 
reportable. However, the NTSB would not likely be concerned with 
collecting data concerning or investigating such events; therefore, the 
NTSB has narrowed the language of this section. The NTSB maintains that 
this change in the proposed regulatory language is a logical outgrowth 
of the proposed rule and therefore does not violate the rulemaking 
requirements of the Administrative Procedure Act (APA).
    The NTSB received three comments that addressed this notification 
requirement. Two commenters stated that they had difficulty determining 
exactly what types of failures for which notification was required. One 
commenter provided an example of an electronic display on a general 
aviation aircraft where a mechanical indication was also included. This 
commenter was concerned that when the electronic display failed, this 
event would have to be reported even though a mechanical display of the 
information was still available. The other commenter stated that the 
criteria for reporting should be based on the aircraft's certification 
requirements.
    Based on these comments and the NTSB's careful review of the 
proposed language of the notification requirement, the NTSB decided 
that some adjustment of the language of this section was required to 
ensure that the relevant failures will be reported, as described above. 
The NTSB's principal goal in promulgating this requirement is to 
capture ``display blanking'' events in which many of the newer ``glass 
cockpit'' type displays have gone blank. The proposed language of this 
requirement was intended to capture this type of failure, but the NTSB 
recognizes that a revision specifically mentioning the various types of 
displays would be advantageous. Therefore, the NTSB has changed the 
language of this subsection to require the reporting of any ``complete 
loss of information, excluding flickering, from more than 50 percent of 
an aircraft's cockpit displays known as: (A) Electronic Flight 
Instrument System (EFIS) displays; (B) Engine Indication and Crew 
Alerting System (EICAS) displays; (C) Electronic Centralized Aircraft 
Monitor (ECAM) displays; or (D) Other displays of this type, which 
generally include a primary flight display (PFD), primary navigation 
display (PND), and other integrated displays.''

[[Page 925]]

    Furthermore, another commenter disagreed with the exclusion of 
``flickering'' of instrument displays when considering the reporting 
requirements in this section. The commenter felt that the 
``flickering'' of displays could be an indication of underlying 
hardware or software problems. The NTSB considered this potential 
meaning of ``flickering'' when it originally defined the language of 
this section. After reviewing this concept, the NTSB has decided 
against revising the language of this section. While the NTSB agrees 
that ``flickering'' can be a symptom of underlying problems, the NTSB 
feels that the operator's maintenance organization is best equipped to 
deal with this type of symptom. If the ``flickering'' becomes so severe 
that the display is unusable, then it should be reported under this 
section (providing that over 50 percent of the displays were similarly 
unusable).
    One commenter stated that the requirement to report these types of 
failures to the NTSB constituted a duplicative reporting requirement, 
as failures are already required to be reported to the FAA. The NTSB 
feels that the requirement to report these types of failures directly 
to the NTSB is essential to aviation safety because it ensures that 
these events will be investigated by NTSB personnel as quickly as 
possible. In addition, duplicative notifications are not required 
because the regulations state that any incident reported to the NTSB 
does not have to be reported separately to the FAA.
    As described above, the NTSB continues to believe that it is in the 
best interest of aviation safety to receive reports of a complete loss 
of information from certain types of electronic displays. After 
carefully considering all comments that addressed this section, the 
NTSB has determined that it must receive notification of complete 
losses of information, as described above. Consistent with the above 
discussion, the NTSB has amended this addition.

Proposed Addition of Section 830.5(a)(10)

    The NPRM proposed to add section 830.5(a)(10) to 49 CFR Part 830 to 
require the reporting of the following: Airborne Collision and 
Avoidance System (ACAS) resolution advisories issued either: When an 
aircraft is being operated on an instrument flight rules flight plan 
and corrective or evasive action is required to maintain a safe 
distance from other aircraft; or to an aircraft operating in class A 
airspace.
    The intent of this requirement is for the NTSB to be notified of 
incidents where ACAS-equipped aircraft must actively maneuver to avert 
a substantial risk of collision with another aircraft and to be 
notified of incidents where the stringent separation requirements 
inherent in operations within class A airspace may have been 
compromised. The NTSB has carefully reviewed the comments received 
concerning this requirement and amends the language of this requirement 
to require reports of ACAS resolution advisories issued either (A) when 
an aircraft is being operated on an IFR flight plan and compliance with 
the advisory is necessary to avert a substantial risk of collision 
between two or more aircraft; or (B) to an aircraft operating in class 
A airspace.
    Five commenters were concerned that the original proposed 
requirement would result in an unmanageable number of reports. In 
general, regarding the proposed rule's effect outside class A airspace, 
commenters placed most of their emphasis on the ``corrective or evasive 
action'' language, despite the language that a report would be 
necessary only when such maneuvers are ``* * * required to maintain a 
safe distance from other aircraft.'' The NTSB fully recognizes that 
when a resolution advisory occurs, it does not necessarily follow that 
an unsafe encounter is about to occur. The NTSB intends to require 
reports only when failure to comply with a resolution advisory would 
lead to an unsafe encounter with another aircraft, that is, an 
encounter presenting a substantial risk of collision. The NTSB's 
expectation is that there are not an unmanageable number of such 
encounters occurring in the air traffic control (ATC) system. However, 
if reports show that a large number of these incidents are occurring, 
the circumstances leading up to the incidents would certainly be a 
safety issue of major interest to the NTSB. Concern about dealing with 
the associated reports is not a persuasive rationale for not requiring 
them, especially if the number of serious incidents is unexpectedly 
high. The NTSB believes that by further clarifying the definition of 
incidents to be reported, the burden on both aircraft operators and the 
NTSB will be limited to addressing high-risk events that warrant 
further examination and potentially full investigation.
    The NTSB recognizes that ``substantial risk of collision'' is 
somewhat subjective, but the infinite variety of encounter geometries 
does not lend itself to specific guidance that would apply to every 
possible scenario. The FAA's definition of a near midair collision is 
``an incident associated with the operation of an aircraft in which a 
possibility of collision occurs as a result of proximity of less than 
500 feet to another aircraft, or a report is received from a pilot or a 
flight crew member stating that a collision hazard existed between two 
or more aircraft.'' This definition is not incorporated to limit or 
precisely define the reports desired, but it may be useful in 
illustrating the nature of the types of incidents for which the NTSB 
will require notification. Resolution advisories that command maximum 
vertical speed, ``reversal'' advisories that require a change in 
vertical direction after the initial advisory is issued, or encounters 
that result in zero vertical separation between the aircraft involved 
are all examples of the types of advisories that the NTSB believes may 
be indicative of substantial collision risk. Conversely, resolution 
advisories issued to aircraft operating on closely spaced parallel 
approaches or in other circumstances where there is no substantial risk 
of collision need not be reported under this rule.
    Four commenters stated that this requirement would effectively 
mandate the reporting of all resolution advisories. As stated above, 
the NTSB does not intend for all resolution advisories to be reported. 
The NTSB expects that the revised language fully addresses this concern 
and explicitly limits the need for reporting to situations where 
compliance with a resolution advisory is necessary to avert a 
significant risk of collision.
    Two commenters expressed concern about the potential need to 
download flight recorder data or remove recorders from aircraft, 
thereby incurring expense and potential schedule disruption to the 
aircraft operator. As the NTSB has previously noted, requiring an 
operator to provide flight recorder data can be disruptive and 
burdensome. The NTSB carefully considers the need for such information 
in determining how to investigate serious incidents properly and limits 
requests to situations where the data is clearly required to understand 
the sequence of events because other available information, such as 
recorded radar data, is inadequate. Unless a large number of unreported 
serious incidents occur, the NTSB does not expect to substantially 
increase the number of recorder requests made to support this reporting 
requirement.
    Two commenters stated that the NTSB should rely on the FAA for 
reports of traffic alert and collision avoidance system (TCAS) events. 
The NTSB does not believe that the FAA's processes for assessing and 
reporting

[[Page 926]]

incidents, particularly those involving losses of separation, are 
sufficiently reliable. Recent Department of Transportation Inspector 
General investigations have documented repeated failures to report 
incidents, misclassification of incidents, and other circumstances 
which lead the NTSB, as an independent agency, to seek additional means 
of monitoring the performance of the ATC system. The NTSB expects that 
information provided by aircraft operators under this reporting 
requirement will help validate the effectiveness of the FAA's reporting 
process, especially relating to more serious incidents occurring in the 
system. One of the commenters noted that the NTSB should, in lieu of 
the proposed reporting requirement, correct the FAA's procedures. The 
NTSB does occasionally interact with the FAA regarding the efficacy of 
its internal processes. However, the NTSB has no authority to direct 
changes to FAA procedures. The NTSB believes that for the significant 
types of incidents the NTSB expects to investigate under this 
requirement, occasional duplicative reports are worthwhile to ensure 
that a complete examination of the circumstances takes place.
    Five commenters stated that the proposed reporting requirement 
should be dropped in favor of existing voluntary confidential data 
collection systems such as the Aviation Safety Action Program (ASAP), 
Flight Operational Quality Assurance (FOQA) programs, and the MITRE-
operated Aviation Safety Information Analysis and Sharing program. 
While the NTSB does support such programs in principle, the de-
identified and otherwise filtered information available through them is 
not useful for investigative purposes. The NTSB's duty is to define the 
types of events that may warrant a safety investigation, evaluate those 
events as they occur, and investigate as necessary. Existing NTSB 
reporting requirements predated and, to a large extent, overlap with 
the types of incidents and accidents for which reports are made to 
these programs. Nonetheless, the NTSB continues to define reporting 
requirements and investigate safety incidents as necessary to protect 
the public interest. The NTSB cannot delegate such responsibilities to 
external organizations, become wholly dependent on information such 
organizations may or may not see fit to share, or limit the 
investigative use of that information to comply with accompanying 
restrictions. Therefore, the NTSB does not view the data collection 
programs suggested by the commenters as an adequate substitute for the 
proposed reporting requirement.
    One commenter noted that pilots may not report incidents without 
the protection of an ASAP or FOQA program and further inquired about 
the possible consequences of failing to report such incidents. While a 
pilot's decision to disregard a reporting requirement is an unfortunate 
possibility, it is beyond the control of the NTSB. The NTSB presumes 
good faith on the part of professional aviators with regard to 
reporting, and the NTSB does not intend to use this requirement to 
prompt enforcement actions.
    The NTSB emphasizes that the intent of this reporting requirement 
is to identify, evaluate, and investigate (when appropriate) serious 
incidents where aircraft maneuvers were required to avert substantial 
risk of collision between TCAS-equipped aircraft and other aircraft in 
the system and to evaluate situations where resolution advisories occur 
between aircraft under positive control in class A airspace. The NTSB's 
intent is not to require the reporting of all resolution advisories or, 
outside of class A airspace, to require the reporting of any resolution 
advisory resulting from an encounter between aircraft where no 
substantial risk of collision exists.
    In summary, the NTSB continues to believe that this reporting 
requirement will achieve the NTSB's objective of receiving notification 
of aircraft encounters that present a significant risk of collision. 
The NTSB, however, has determined that amending the language will 
provide further clarity and assist operators, crews, and other 
individuals and entities affected by this rule in recognizing that the 
NTSB seeks notification of the category of occurrences in which 
hazardous encounters involving ACAS-equipped aircraft occur. As such, 
the NTSB will require notification of the following: Airborne Collision 
and Avoidance System (ACAS) resolution advisories issued either: when 
an aircraft is being operated on an instrument flight rules flight plan 
and compliance with the advisory is necessary to avert a substantial 
risk of collision between two or more aircraft; or to an aircraft 
operating in class A airspace.

Proposed Addition of Section 830.5(a)(11)

    The NPRM proposed to add section 830.5(a)(11) to 49 CFR Part 830 to 
require that the public report ``[d]amage to helicopter tail or main 
rotor blades, including ground damage, that requires major repair or 
replacement of the blade(s).'' The NTSB did not receive any comments 
concerning this proposed requirement. Moreover, the NTSB continues to 
believe that the proposed reporting requirement will achieve the NTSB's 
objective of receiving notification of all rotor blade strikes that 
result in damage, regardless of what the blades strike. Therefore, the 
NTSB has not amended this addition and will require notification of any 
damage to helicopter tail or main rotor blades that requires major 
repair or replacement of the blade(s).

Proposed Addition of Section 830.5(a)(12)

    The NPRM proposed to add section 830.5(a)(12) to 49 CFR Part 830 to 
require that the public report the following: Any runway incursion 
event in which an operator, when operating an aircraft as an air 
carrier: lands or departs on a taxiway, incorrect runway, or other area 
not designed as a runway; or experiences a reduction in separation that 
requires the operator or another aircraft or vehicle to take immediate 
corrective action to avoid a collision.
    The NTSB received one comment on this section, which partially 
concurred with the proposal and provided suggestions. The commenter 
stated that the phrase ``runway incursion'' in the qualifying statement 
should be deleted because landing and taking off on a taxiway is not a 
runway incursion. Additionally, the commenter stated that the reporting 
requirements should include nonrevenue operations (such as ferry 
flights, maintenance flights/taxi, and reposition flights/taxi). 
Finally, the commenter believed that events resulting in a go-around 
should be excluded because that would require a report each time a go-
around was conducted if an aircraft or vehicle was on the runway. 
Although the commenter believed that the events as stated should be 
reportable, the commenter felt that the language should be clarified.
    The NTSB agrees that the term ``runway incursion'' should be 
deleted from the beginning of the statement for the reasons provided by 
the commenter. However, to clarify that the NTSB is requesting reports 
of separation issues on the runway, the NTSB hereby amends subsection 
(B) to restrict reports to runway operations. The NTSB also agrees with 
the commenter's suggestion to include nonrevenue flights because the 
same pilots fly both revenue and nonrevenue flights.
    Finally, the commenter opined that all go-around maneuvers 
conducted because the runway was not clear would need to be reported. 
The NTSB disagrees with this assessment. For

[[Page 927]]

example, if a controller instructs the pilot to go around because an 
aircraft or vehicle is on the runway, that is a controlled situation. 
The tower controller was aware of the situation and directed a go 
around. However, if the pilot had to execute a go-around on his own and 
the tower controller was not aware of the situation, the NTSB would 
want to know about that event because it may go unreported. Similarly, 
a tower controller could clear an aircraft to land and inadvertently 
clear another aircraft onto the runway; if the arriving pilot has to 
conduct a go-around because of the airplane on the runway, the NTSB 
should receive a report of the incident.
    Based on the NTSB's careful review of the above commentary, the 
NTSB will now require the reporting of ``[a]ny event in which an 
aircraft operated by an air carrier: (A) [l]ands or departs on a 
taxiway, incorrect runway, or other area not designed as a runway; or 
(B) [e]xperiences a runway incursion that requires the operator or the 
crew of another aircraft or vehicle to take immediate corrective action 
to avoid a collision.''
    The NTSB has concluded that this clarification in the regulatory 
language is a logical outgrowth of the proposed language and is 
therefore consistent with the rulemaking requirements of the APA.
