ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: This rulemaking would increase the recording time of cockpit
voice recorders from the mandated 2 hours to a proposed 25-hour
recording time for all future manufactured aircraft. This rulemaking
would provide accident investigators, aircraft operators, and civil
aviation authorities with substantially more cockpit voice recorder
data to help find the probable causes of incidents and accidents,
prevent future incidents and accidents, and make the FAA's regulations
more consistent with existing international requirements.

SUPPLEMENTARY INFORMATION:
Authority for This Rulemaking
The FAA's authority to issue rules on aviation safety is found in
title 49 of the United States Code. Subtitle I, section 106 describes
the authority of the FAA Administrator. Subtitle VII, Aviation
Programs, describes in more detail the scope of the FAA's authority.
This rulemaking is issued under the authority described in subtitle
VII, part A, subpart III, section 44701. Under that section, the FAA is
charged with prescribing regulations providing minimum standards for
other practices, methods, and procedures necessary for safety in air
commerce. This regulation is within the scope of that authority since
flight data recorders are the only means available to account for
aircraft movement and flight crew actions critical to finding the
probable cause of incidents or accidents, including data that could
prevent future incidents or accidents.
I. Executive Summary
A. Overview of Proposed Rule
This rulemaking effort proposes to amend the cockpit voice recorder
(CVR) regulations to increase the recording duration of CVRs.
Currently, CVRs are required to retain the last two hours of recorded
information. Once this 2-hour limit is reached, a CVR overwrites the
oldest data to maintain a rolling 2-hour recording. This proposal would
increase the minimum duration of CVR recordings to 25 hours. The
proposed change would affect all newly manufactured aircraft operating
under title 14 of the Code of Federal Regulations (14 CFR) parts 91,
121, 125, and 135, one year after the effective date of the final rule.
B. Statement of the Problem
The current 2-hour recording duration requirement does not meet the
NTSB's needs for investigations and subsequent safety recommendations.
Since the NTSB issued Safety Recommendation A-18-030, it has
investigated numerous accidents and incidents where CVR data relevant
to the accident or incident has been overwritten because the relevant
recording occurred earlier than the available two hours of recording.
C. Summary of the Costs and Benefits
Benefits of the proposed rule are expected to stem from a reduction
in accident risk and time savings. Specifically, the additional audio
of longer duration CVRs would provide authorities with more information
on events and procedures undertaken in the flight deck in investigated
incidents. This increased data may lead to new or more fully informed
FAA recommendations or policy changes that could further enhance safety
and reduce the risk that an incident becomes an accident. In addition,
updated CVR models have also revamped the CVR interface tools,
resulting in time-saving benefits. The simplified and more intuitive
tools allow personnel to be trained quicker on operation, retrieve
audio data faster, and perform additional diagnostic services to
shorten downtime. The FAA currently lacks data to predict the exact
reduction in accident risk and labor hours and requests comments on the
expected value of these benefits.
The FAA has assessed projected compliance costs using the
incremental cost of equipping a 25-hour capable CVR over a comparable
2-hour unit to all applicable newly produced aircraft. Market research
indicates that the difference between these units is minimal, ranging
from near parity to an upper bound of approximately $4,500. Using that
upper bound, the total cost over 20 years is estimated to be $102.42
million at 7 percent present value, with annualized costs of $9.67
million. As operational procedures are expected to be similar between
the older 2-hour and newer 25-hour capable models, the FAA anticipates
no other notable costs. The FAA invites comments on the cost estimates
and assumptions.
II. Background
A. CVRs: National Transportation Safety Board (NTSB) Recommendations
and FAA Responses
The FAA previously has engaged in rulemaking to address past NTSB
recommendations concerning CVRs.
[[Page 84091]]
In December 1996, the NTSB issued Safety Recommendation A-96-171 as
a result of its investigation of an accident in January 1996.\1\ In
this accident, an aircraft touched down hard in the approach light area
short of a runway at the Nashville International Airport, resulting in
minor injuries to passengers and crew and substantial damage to the
aircraft's tail section, nose gear, and engines. During the
investigation, the NTSB was hampered by the fact that the 30-minute
closed-loop CVR tape did not include recordings of the initial approach
to the runway, the hard landing event, or the go-around because that
information had been recorded over and permanently lost after the
airplane safely stopped on the ground.\2\ As a result, the NTSB
recommended that the recording limitation for newly manufactured CVRs
meet a minimum recording duration of two hours.\3\ The FAA adopted this
recommendation in 2008.

---------------------------------------------------------------------------
In August 2002, the NTSB issued a safety recommendation letter to
the FAA, identifying delays or failures by the operator to deactivate
CVRs after reportable events as a major factor in the systemic problem
of retaining data, as information was overwritten in the remainder of a
flight with an incident or accident.\4\ The NTSB recommended that the
FAA require the CVR be deactivated immediately upon completion of
flight after a reportable incident or accident has occurred. In
response, the FAA issued Notice 8400.48, ``Cockpit Voice Recorder
Deactivation After a Reportable Event,'' on April 25, 2003. This notice
advised air carriers to add a checklist item to deactivate the CVR,
manually or automatically, immediately upon completion of a flight with
a reportable accident or incident. On October 6, 2003, the NTSB
considered Notice 8400.48 to have met the intent of Safety
Recommendation A-02-24 for aircraft operating under parts 121 and 135
requirements, but not part 91 requirements as the notice did not
address part 91 operators.\5\

On March 7, 2008, the FAA amended the CVR regulations in accordance
with NTSB Safety Recommendation A-96-171.\6\ The final rule,
``Revisions to Cockpit Voice Recorder and Digital Flight Data Recorder
Regulations,'' increased the duration of certain CVR recordings,
increased the data recording rate for certain digital flight data
recorder (DFDR) parameters, physically separated DFDRs and CVRs,
improved power supply to both CVRs and DFDRs, and required certain
datalink communications received on an aircraft to be recorded if
datalink communication equipment was installed.\7\

---------------------------------------------------------------------------
On October 10, 2018, the NTSB published an Aviation Safety
Recommendation Report titled ``Extended Duration Cockpit Voice
Recorders.'' Within this safety report, Safety Recommendation A-18-030
recommended that the FAA require all newly manufactured aircraft that
must have a CVR to be fitted with and operate a CVR capable of
recording the last 25 hours of audio. This recommendation stemmed from
an aircraft incident that occurred in July 2017 at San Francisco
International Airport, in which the flight crew of an Airbus A320 was
cleared to land on a set runway but instead lined up with a parallel
taxiway. After descending to an altitude of 100 feet above ground level
(AGL), the aircraft overflew an airplane on the taxiway. The incident
aircraft subsequently overflew a second airplane on the taxiway before
starting to climb.
During the investigation of the incident, the NTSB found it
difficult to gather relevant information as the CVR data was
overwritten before Air Canada officials learned of the severity of the
event. The report stated that had the NTSB been able to obtain the
overwritten data, investigators would have been able to assess the
timing and content of the flight crew's conversations during final
approach, conversations during and after the go-around, and the flight
crew's crew resource management (CRM), workload, and fatigue based on
verbalizations or flight deck sounds. In this instance, the NTSB
identified several serious safety issues; however, this investigation
lacked direct evidence of the flight crew's decision making,
coordination, and perception of its environment.
B. FAA Aviation Safety Summit of 2023
On March 15, 2023, the FAA convened an aviation safety summit,
where approximately 200 safety leaders from the aviation industry met
to discuss safety improvements in response to several recent near-miss
incidents and runway incursions.\8\ The summit focused on ways to
enhance flight safety for commercial operations, the air traffic
system, airport and ground operations, and general aviation operations.

---------------------------------------------------------------------------
As a result of discussions at the summit, the FAA committed to
initiate rulemaking that would require CVRs to capture 25 hours of
information for newly manufactured aircraft.
C. ICAO and EASA Adoption of a 25-Hour Cockpit Voice Recorder
Requirement
In 2013, the European Union Aviation Safety Agency (EASA) proposed
an amendment that would have required large commercial aircraft
manufactured after January 1, 2019, to carry a CVR capable of recording
the last 15 hours of aircraft operation.\9\ In 2015, after considering
the comments received on the proposed amendment and after technical
review, EASA extended the recording duration requirement to 25
hours.\10\ The 25-hour mandate took effect on January 1, 2021. The
regulation requires any aircraft with a maximum takeoff weight of
27,000 kg (60,000 pounds) or more, manufactured after January 1, 2021,
to be equipped with a CVR with at least a 25-hour recording
capability.\11\

In 2016, the International Civil Aviation Organization (ICAO) also
adopted a new standard calling for the installation of CVRs capable of
recording the last 25 hours of aircraft operation on all aircraft
manufactured after January 1, 2021, with a maximum certificated takeoff
mass of over 27,000 kg and engaged in commercial transport.\12\ In
adopting this standard, ICAO emphasized the value of CVR recordings in
analyzing human factors and other sounds.\13\ ICAO noted that extending
the recording duration of CVRs was necessary to cover the longest
flight duration, including pre- and postflight activities, delays, and
the time required to secure the recordings.\14\

III. Discussion of the Proposal
Since the FAA updated the CVR regulations in 2008, the NTSB has
reported issues with accessing relevant CVR data with existing 2-hour
recording duration. Numerous aircraft incidents have occurred in which
relevant CVR data was overwritten and thereby made unavailable because
of the time it took to retrieve the CVR. The lack of relevant CVR data
hampers NTSB investigations and its ability to provide appropriate
safety recommendations that can help prevent future accidents and
incidents.\17\
---------------------------------------------------------------------------
\17\ NTSB. (March 15, 2023). Transcript of NTSB Chair's Remarks
at the FAA Safety Summit. www.ntsb.gov/Advocacy/Activities/Pages/Homendy-20230315.aspx.
---------------------------------------------------------------------------
In response to Safety Recommendation A-18-030, the FAA proposes to
amend all CVR operational regulations related to CVR recording time by
expanding the recording duration from two hours to 25 hours for
aircraft manufactured one year after the date of publication of the
final rule.
The NTSB's Safety Recommendation also included the recommendation
to retrofit the current fleet. While retrofitting the current fleet
would more expeditiously increase the number of aircraft fitted with
the newer 25-hour CVR units and, thereby, the projected benefits to
safety, the costs would be significant. Specifically, retrofitting the
current fleet would increase by two-thirds the number of aircraft
required to install 25-hour CVRs (estimated 29,561 aircraft in the
current fleet added to the estimated 43,470 aircraft being built in the
next 20 years). Further, the cost to retrofit existing aircraft with
25-hour CVRs would be several times higher than the cost to equip
future-built aircraft with a 25-hour CVR instead of a 2-hour model.
Assuming no replacement, applying a $25,000 CVR unit cost spread across
the estimated 29,651 current fleet would result in roughly $741.28
million (undiscounted) in equipment cost compared to the $195.62
million (undiscounted) in incremental upgrade costs from the proposed
rule. Retrofitting current aircraft would also incur additional costs,
such as aircraft downtime and labor hours required to replace the CVR
unit, which would further increase the total cost. Therefore, in an
effort to provide the increased benefit of making more substantive data
available to accident investigators while maintaining the lowest
economic impact on operators, this proposed rule would apply to newly
manufactured aircraft only. For more information, please see the
regulatory impact analysis in the docket.
The proposed change would affect the following regulations:
Section 91.609(i)(2);
Section 121.359(i)(2);
Section 121.359(j)(2);
Section 125.227(g)(2);
Section 125.227(h)(2);
Section 135.151(g)(1)(iii); and
Section 135.151(g)(2)(iii).
Certificate holders operating under part 129 requirements would be
affected because, in accordance with Sec. 129.24, their CVRs are
required to record as if the aircraft were operated under parts 121,
125, or 135.
A. Cockpit Voice Recorder Capabilities and Investigative Use
Aircraft operating under parts 91, 121, 125, and 135 are required
to be equipped with a CVR that records radio transmissions and sounds
in the flight deck to aid subsequent investigation should an accident
or incident occur. The recorder's flight deck area microphone is
usually located on the overhead instrument panel between the two
pilots.
CVRs preserve the recent history of sounds in the flight deck and
provide unique information such as engine noise, stall warnings,
landing gear extension and retraction, and other clicks and pops. These
sounds may help an investigator to determine parameters such as engine
rpm, system failures, speed, and the time at which certain events
occur. The CVR also records communications with Air Traffic Control,
automated radio weather briefings, conversations between the pilots and
ground or cabin crew, flight crew verbalizations of intentions and
coordination, as well as the pilots' awareness of the aircraft and
flight deck information.\18\ Access to this information allows
investigators to more thoroughly investigate accident and incident
factors. Incident factors include the flight crew's procedural
compliance, distraction, decision-making, workload, fatigue, and
situational awareness.

Data Recorders (FDR).'' www.ntsb.gov/news/Pages/cvr_fdr.aspx.
---------------------------------------------------------------------------
A CVR starts recording when an aircraft is powered up and will
continue to record until the aircraft is powered down or the CVR is
deactivated. Once a CVR reaches the end of its recording limit, it will
overwrite existing data with a new recording.
CVRs typically deactivate due to two forms of power loss. The first
occurs when the CVR is deactivated after a major or catastrophic event
causing a loss of electrical power. When this event occurs, the CVR
preserves relevant audio recorded in the two hours prior to the
accident. The second form occurs during less severe incidents, such as
when the flight crew manually deactivates the CVR immediately upon
landing in order to prevent the relevant audio from being overwritten.
After an accident or incident, the CVR data is transferred to an
NTSB lab for retrieval. The NTSB will eventually receive a readout from
the CVR software.
Since CVRs were implemented in 1966, recording capabilities have
significantly increased from the original 30 minutes. The latest
designs employ more easily expandable solid-state memory and use fault
tolerant digital recording technique with an incorporated battery so
that recording can continue until the end of flight, even when the
aircraft's electrical system fails.
The technical limit for recording time has expanded such that 25
hours is now well within CVR capability. In addition, because both EASA
and ICAO have adopted a 25-hour CVR recording duration minimum for
aircraft manufactured after January 1, 2021, multiple manufacturers
already produce CVRs capable of recording for 25 hours.
B. National Transportation Safety Board
Since 2008, the NTSB has expressed concerns regarding the
availability of CVR information, the length of CVR recording time, and
how to prevent relevant information from being overwritten after an
incident or accident. The current 2-hour recording requirement has not
fully resolved the issue of overwritten data, which continues to
negatively impact NTSB investigations.
There are two common causes for CVR data to be overwritten. First,
there may be a delay between a safety event and the flight crew
recognizing that event to be a serious incident or accident, resulting
in the relevant CVR data being overwritten as the CVR continued to
record throughout the delay. Second, the recording of a safety event
may be overwritten during the course of the flight itself (e.g., where
flight duration exceeds the 2-hour CVR recording duration).
[[Page 84093]]
The NTSB reported that, in 2017, approximately 56 percent of U.S.
block times \19\ consisted of long and medium flights with durations
longer than two hours, including some international flights lasting
over 12 hours.\20\ When ICAO adopted the standard for the installation
of 25-hour CVRs in 2016, it noted that extended duration of CVRs is
necessary to cover the longest duration of flights, including pre- and
postflight activities, delays, and the time required to secure the
recordings.\21\
---------------------------------------------------------------------------
\19\ ICAO defines block time to include the moment an aircraft
is pushed back from the gate to the moment it comes to a final stop
at a gate or parking stand after landing.

Since the 2-hour standard came into effect in 2008, numerous
accidents and incidents have occurred where the CVR data was
overwritten and, had it been available, would have positively
contributed to NTSB investigations. Notable incidents include the
following:

----------------------------------------------------------------------------------------------------------------
In addition to the incidents noted by the NTSB, CVR data overwrites
have hampered several other investigations. For example, on October 21,
2009, an incident occurred on a 4-hour flight where the flight crew did
not communicate with air traffic control for about 1 hour and 17
minutes, during which time the airplane overflew its intended location
at a cruise altitude of 27,000 ft.\22\ The flight crew later reported
that ``cockpit distractions'' led to the event. The airplane's CVR had
a 30-minute recording duration; upon review, the NTSB discovered that
all pertinent information had been overwritten by the remaining two
hours and 11 minutes of the 4-hour flight.\23\ Even if the airplane had
been equipped with a CVR recording for two hours, the information still
would have been overwritten. Having lost this CVR data to overwriting,
the NTSB was unable to determine the nature of the flight crew's
distraction, the events that led to the distraction, why the
distraction lasted for as long as it did, and what mitigating
procedures or actions could have prevented that distraction.

More recently, on January 13, 2023, a runway incursion incident
occurred at John F. Kennedy (JFK) Airport in New York, New York. The
incursion involved a taxiing Boeing 777-200 and a Boeing 737-900ER
cleared for takeoff. The Boeing 777-200 accessed a taxiway without Air
Traffic Control (ATC) clearance, crossing the runway that the Boeing
737-900ER was utilizing for takeoff. ATC was notified of the potential
conflict, cancelled the Boeing 737-900ER's takeoff clearance, and the
flight crew aborted the flight. Because the incident did not result in
any damage or injuries, the two flights eventually took off to their
respective destinations. During its investigation, the NTSB discovered
the CVR data for both flights had been overwritten.
On February 4, 2023, a runway incursion occurred at Austin
Bergstrom International Airport (AUS) when a Boeing 767F freighter
attempted to land on a runway from which a Boeing 737-700 was also
cleared to depart.\24\ Due to poor weather conditions, the Boeing 767F
crew did not see the conflict until late in the approach, and the two
planes came close to colliding; specifically, the Boeing 767F needed to
overfly the Boeing 737-700 to avoid a collision. There were no injuries
reported to the 128 passengers and crew onboard the Boeing 737-700 or
to the 3 crew members onboard the Boeing 767F. During its
investigation, the NTSB discovered the CVR data for both flights had
been overwritten.

---------------------------------------------------------------------------
The FAA had sought to prevent such recording issues by creating the
retention requirements found in Sec. Sec. 91.609(g), 121.343(i), and
135.152(e), where an operator must remove the recording media following
an accident or incident and keep the recorded data for at least 60
days, or longer if necessary. The FAA also provided guidance in
Advisory Circular 20-186, ``Airworthiness and Operational Approval of
Cockpit Voice Recorder Systems,'' \25\ which recommended the operator
to address CVR recording retention after an accident or incident in its
maintenance and operational programs, such as inclusion in a flight
crew checklist, or in the company standard operating procedures or
emergency procedures. However, since recording issues continue to
occur, the
[[Page 84094]]
FAA agrees with the NTSB that an extension to the CVR recording
duration requirement to 25 hours is warranted.

C. Privacy Concerns
The FAA acknowledges that pilot-focused organizations may have
concerns regarding how the NTSB or the FAA would use the CVR data
collected for investigative purposes.
This issue previously arose when the FAA increased the CVR
recording duration from 30 minutes to 2 hours. At that time, the FAA
determined that the investigative need and benefit of this information
outweighed these privacy concerns.\26\ The FAA maintains this stance.
The proposed increase to a 25-hour CVR recording duration would further
improve current investigative capabilities. It would also provide
investigating bodies, such as the NTSB, with more complete context
surrounding the accidents and incidents under investigation and support

\26\ Revisions to Cockpit Voice Recorder and Digital Flight Data
Recorder Regulations. 73 FR 12541, 12544 (March 7, 2008).
---------------------------------------------------------------------------
Importantly, this proposed increase is designed to provide more
context for any flight deck activity that might be pertinent to an
investigation. Specifically, this increase expands the possible range
of data available to investigators. This proposal does not alter or
modify the existing processes for requesting or use of this data.
Sections 91.609(g), 121.359(h), 121.227(f), and 135.151(c) specify that
the information obtained from the CVR recording is to be used for
investigation purposes and that the FAA will not use the CVR record in
any civil penalty or certificate action. This proposal does not modify
these regulations.
D. International Requirements
ICAO and EASA both require the carriage of CVRs with 25-hour
recording duration on airplanes with a maximum certificated takeoff
mass of more than 27,000 kg. These are aircraft that have the
capability to fly transatlantic or international flights, i.e., long-
haul flights that can last ten or more hours. In contrast, the FAA
requirement would apply to all newly manufactured aircraft required to
carry a CVR, based on existing operating rules. This distinction
reflects differences between the FAA and ICAO/EASA regulatory schemes:
the FAA's existing regulatory scheme differentiates aircraft by
operation type, not by weight. This rulemaking would not change that
regulatory scheme.
With both EASA and ICAO amending their CVR rules to require 25
hours of audio recording time, this proposed change also presents an
opportunity to ensure U.S. regulations are consistent in intent with
international authorities. This should lead to a reduction of risk for
some operators who would otherwise face conflicting requirements and
the cumbersome task of ascertaining guidance for the appropriate
authorities in an attempt to satisfy differing regulations.
Historically, the FAA has implemented CVR regulations by operation
unlike ICAO and EASA, which put forth their standards and regulations
by aircraft weight. As a result, the FAA's proposal would encompass
more aircraft than international requirements would because newly
manufactured aircraft with less than a maximum takeoff weight of 27,000
kg would be affected.
E. Conclusion and Compliance
The FAA concurs with the NTSB's recommendation and believes that
extending CVR recording duration to 25 hours would increase aviation
safety by providing investigative bodies with more thorough context and
background surrounding accidents and incidents. This proposal would
also make FAA regulations more consistent with ICAO recommendations and
EASA requirements.
Given that the technology already exists to implement this
proposal, the FAA proposes a compliance deadline for newly manufactured
aircraft of one year after the effective date of the final regulation.
Any aircraft with a newly issued airworthiness certificate dated on or
after that compliance date would be required to be equipped with a CVR
with 25-hour recording duration.
In addition, the FAA will update the version of the technical
standard order (TSO) referenced in the regulatory text from TSO-C123a
to the latest version, TSO-C123c, for newly manufactured aircraft.
IV. Regulatory Notices and Analyses
Federal agencies consider impacts of regulatory actions under a
variety of Executive orders and other requirements. First, Executive
Order 12866 and Executive Order 13563, as amended by Executive Order
14094 (``Modernizing Regulatory Review''), direct that each Federal
agency shall propose or adopt a regulation only upon a reasoned
determination that the benefits of the intended regulation justify the
costs. Second, the Regulatory Flexibility Act of 1980 (Pub. L. 96-354)
requires agencies to analyze the economic impact of regulatory changes
on small entities. Third, the Trade Agreements Act (Pub. L. 96-39)
prohibits agencies from setting standards that create unnecessary
obstacles to the foreign commerce of the United States. Fourth, the
Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4) requires agencies
to prepare a written assessment of the costs, benefits, and other
effects of proposed or final rules that include a Federal mandate that
may result in the expenditure by State, local, and tribal governments,
in the aggregate, or by the private sector, of $100 million or more
(adjusted annually for inflation) in any one year. The current
threshold after adjustment for inflation is $177 million using the most
current (2022) Implicit Price Deflator for the Gross Domestic Product.
The FAA has provided a detailed Regulatory Impact Analysis (RIA) in the
docket for this rulemaking. This portion of the preamble summarizes the
FAA's analysis of the economic impacts of this proposed rule.
In conducting these analyses, the FAA has determined that this
proposed rule: will result in benefits that justify costs; is not an
economically ``significant regulatory action'' as defined in section
3(f)(1) of Executive Order 12866; will not have a significant economic
impact on a substantial number of small entities; will not create
unnecessary obstacles to the foreign commerce of the United States; and
will not impose an unfunded mandate on State, local, or tribal
governments, or on the private sector.
A. Summary of the Regulatory Impact Analysis
Benefits for the proposed rule were assessed qualitatively as the
FAA currently lacks data to make projections on the benefit totals. The
primary expected benefit is changes in safety from a potential
reduction in accident risk. The expanded available audio from this
proposed rule would provide authorities with more information on events
and procedures undertaken in the flight deck in investigated incidents.
This increased data may lead to new FAA recommendations or policy
changes that could further enhance safety and reduce the risk that a
future incident becomes an accident. The reduction in the risk of one
fatality generates benefits equal to the value of statistical life
(VSL), approximately $12.5 million in 2022 according to the Department
of Transportation (DOT).\27\ Given the annualized costs of $9.67
million from this proposed rule,
[[Page 84095]]
reducing the risk of a single fatality in any year due to effective
safety measures resulting from the ability to gather additional CVR
data would generate benefits greater than the expected costs.

Injuries in Preparing Economic Analyses. Office of the Secretary of
Transportation. 2022.
---------------------------------------------------------------------------
Additionally, there are some potential time-saving benefits
associated with the updated CVR model deployment. In updating their CVR
models, manufacturers also have revamped the CVR interface tools. These
simplified and more intuitive tools allow personnel to be trained
quicker on operation, retrieve audio data faster, and perform
additional diagnostic services to shorten downtime. The FAA does not
currently have enough data to predict the value of these benefits and
invites public comments on the expected totals.
The FAA assessed the costs for the proposed rule as the incremental
cost increase of equipping a 25-hour capable CVR instead of a
comparable 2-hour unit to all applicable new aircraft being produced.
The total aircraft that will be built and equipped with the 25-hour CVR
includes projected new aircraft needed to handle future demand
increases as well as estimated replacements for the current fleet.
Market research indicates the cost increase between comparable 2 and
25-hour CVRs to be minimal, ranging from near parity to an upper bound
of approximately $4,500. Using that upper bound as the incremental cost
to equip all applicable projected new aircraft with a 25-hour capable
CVR, the estimated highest total cost over 20 years, at seven percent
present value, is $102.42 million with an annualized cost of $9.67
million (table 2). At three percent present value, the total cost is
$144.77 million with an annualized cost of $9.73 million.

The FAA does not anticipate other costs besides the incremental
costs of forward fitting 25-hour capable CVRs to comply with the
proposed rule. Based on the technical standards for CVRs, market
research indicates that 25-hour models tend to match the older 2-hour
variants in a manner that allows them to be swapped without much
difficulty. This compatibility implies that other operational
procedures and costs should be similar and not result in notable
change. The FAA invites comments on the expected costs for this
proposed rule.
Please see the RIA available in the docket for more details.
B. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) of 1980, Public Law 96-354, 94
Stat. 1164 (5 U.S.C. 601-612), as amended by the Small Business
Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121, 110 Stat.
857, Mar. 29, 1996) and the Small Business Jobs Act of 2010 (Pub. L.
111-240, 124 Stat. 2504 Sept. 27, 2010), requires Federal agencies to
consider the effects of the regulatory action on small business and
other small entities and to minimize any significant economic impact.
The term ``small entities'' comprises small businesses and not-for-
profit organizations that are independently owned and operated and are
not dominant in their fields, and governmental jurisdictions with
populations of less than 50,000.
The proposed rule affects CVR manufacturers by requiring the
development and certification of 25-hour capable models. A major change
to the CVR components, such as in this case, would require a
manufacturer to go through the development and certification of a new
model, which could involve extra cost and time. However, due to EASA
and ICAO standards for 25-hour capability taking effect in 2021, market
research shows that manufacturers already have developed 25-hour
compliant variants that meet FAA TSO-C123 compliance. Therefore, the
proposed regulation is not expected to result in new or significant
impacts on CVR manufacturers. The FAA invites comments on the expected
effects of the proposed rule on CVR manufacturers.
As described in the RIA, the FAA identified six U.S. manufacturers
that would be affected by the proposed rule. Based on the Small
Business Administration (SBA) 2023 size standard for Other Aircraft
Part and Auxiliary Equipment Manufacturing (NAICS 336413),\28\ and on
publicly available data on employment for these entities, all six
identified manufacturers are large businesses that exceed the 1,250-
employee size maximum for a small business. Therefore, the FAA
certifies that the proposed rule will not have a significant economic
impact on a substantial number of small entities because the proposed
rule does not impact any small entity. The FAA welcomes comments on the
number of U.S. CVR manufacturers and this certification.
---------------------------------------------------------------------------
\28\ Small Business Administration (SBA) Size Standards,
effective March 17, 2023, can be found at www.sba.gov/document/support-table-size-standards.
---------------------------------------------------------------------------
C. International Trade Impact Assessment
The Trade Agreements Act of 1979 (Pub. L. 96-39), as amended by the
Uruguay Round Agreements Act (Pub. L. 103-465), prohibits Federal
agencies from establishing standards or engaging in related activities
that create unnecessary obstacles to the foreign commerce of the United
States. Pursuant to these Acts, the establishment of standards is not
considered an unnecessary obstacle to the foreign commerce of the
United States, so long as the standard has a
[[Page 84096]]
legitimate domestic objective, such as the protection of safety, and
does not operate in a manner that excludes imports that meet this
objective. The statute also requires consideration of international
standards and, where appropriate, that they be the basis for U.S.
standards. The FAA has assessed the potential effect of this proposed
rule and determined that it promotes the safety of the American public
and does not exclude imports that meet the recording length
requirement. As a result, the FAA does not consider this proposed rule
as creating an unnecessary obstacle to foreign commerce.
D. Unfunded Mandates Assessment
The Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4) requires
agencies to prepare a written assessment of the costs, benefits, and
other effects of proposed or final rules that include a Federal mandate
that may result in the expenditure by State, local, and tribal
governments, in the aggregate, or by the private sector, of $100
million or more (adjusted annually for inflation) in any one year. The
current threshold after adjustment for inflation is $177 million using
the most current (2022) Implicit Price Deflator for the Gross Domestic
Product.
The FAA determined that the proposed rule will not result in the
expenditure of $177 million or more by State, local, or tribal
governments, in the aggregate, or the private sector, in any one year.
E. Paperwork Reduction Act
The Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)) requires
that the FAA consider the impact of paperwork and other information
collection burdens imposed on the public. According to the 1995
amendments to the Paperwork Reduction Act (5 CFR 1320.8(b)(2)(vi)), an
agency may not collect or sponsor the collection of information, nor
may it impose an information collection requirement unless it displays
a currently valid Office of Management and Budget (OMB) control number.
This action contains the following proposed amendments to the
existing information collection requirements previously approved under
OMB Control Number 2120-0700. As required by the Paperwork Reduction
Act of 1995 (44 U.S.C. 3507(d)), the FAA has submitted these proposed
information collection amendments to OMB for its review.
Summary: This notice proposes to amend parts 91, 121, 125, and 135
requirements so aircraft manufactured on or after [ONE YEAR THE
EFFECTIVE DATE OF THE FINAL RULE] that are required to be installed
with a cockpit voice recorder would be required to have a recording
limit of 25 hours, expanded from the current requirement of 2 hours.
Use: Such a record would provide additional information to accident
and incident investigators to determine flight crew's procedural
compliance, distraction, decision-making, workload, fatigue, and
situational awareness. The expansion to 25 hours would address the
issue in which data is overwritten because the relevant recording
occurred earlier than the available two hours of recording.
Respondents (including number of): The respondents all would be
certificate holders operating the above-referenced U.S.-registered
aircraft under parts 91, 121, 125, 129, and 135. Certificate holders
operating under part 129 requirements would be affected because, in
accordance with Sec. 129.24, a cockpit voice recorder would be
required to record as if the aircraft were operated under parts 121,
125, or 135.
Frequency: The 25 hours of recorded data would be overwritten on a
continuing basis and would only be accessed following an accident or
incident.
Annual Burden Estimate: This proposed requirement would not change
the current information collection activity; therefore, it does not
contain a measurable hour burden.
The FAA is soliciting comments to--
(1) Evaluate whether the proposed information requirement is
necessary for the proper performance of the functions of the FAA,
including whether the information will have practical utility;
(2) Evaluate the accuracy of the FAA's estimate of the burden;
(3) Enhance the quality, utility, and clarity of the information to
be collected; and
(4) Minimize the burden of collecting information on those who are
to respond, including by using appropriate automated, electronic,
mechanical, or other technological collection techniques or other forms
of information technology.
Individuals and organizations may send comments on the information
collection requirement to the address listed in the ADDRESSES section
at the beginning of this preamble by February 2, 2024. Comments also
should be submitted to the Office of Management and Budget, Office of
Information and Regulatory Affairs, Attention: Desk Officer for FAA,
New Executive Office Building, Room 10202, 725 17th Street NW,
Washington, DC 20053.
F. International Compatibility
In keeping with U.S. obligations under the Convention on
International Civil Aviation, it is FAA policy to conform to
International Civil Aviation Organization (ICAO) Standards and
Recommended Practices to the maximum extent practicable. The FAA has
reviewed the corresponding ICAO Standards and Recommended Practices and
has identified the following differences with these proposed
regulations. The proposed rule would harmonize with ICAO regarding the
required length of the CVR recordings at 25 hours. However, the U.S.
does not regulate carriage requirements of CVRs based on the aircraft
gross weight, as do the ICAO and EASA, and the proposed rule change
would not change this. If this proposal is adopted, the FAA intends to
amend its currently filed difference on this topic with ICAO.
G. Environmental Analysis
FAA Order 1050.1F identifies FAA actions that are categorically
excluded from the preparation of an environmental assessment or
environmental impact statement under the National Environmental Policy
Act (NEPA) in the absence of extraordinary circumstances. The FAA has
determined this proposed rulemaking action qualifies for the
categorical exclusion identified in paragraph 5-6.6f for regulations
and involves no extraordinary circumstances.
V. Executive Order Determinations
A. Executive Order 13132, Federalism
The FAA has analyzed this proposed rule under the principles and
criteria of Executive Order (E.O.) 13132, Federalism. The FAA has
determined that this proposed action would not have a substantial
direct effect on the States, or the relationship between the Federal
Government and the States, or on the distribution of power and
responsibilities among the various levels of government and, therefore,
would not have federalism implications.
B. Executive Order 13175, Consultation and Coordination With Indian
Tribal Governments
Consistent with Executive Order 13175, Consultation and
Coordination with Indian Tribal Governments,\29\ and FAA Order 1210.20,
American Indian and Alaska Native Tribal Consultation Policy and
Procedures,\30\ the FAA ensures that Federally Recognized
[[Page 84097]]
Tribes (Tribes) are given the opportunity to provide meaningful and
timely input regarding proposed Federal actions that have the potential
to affect uniquely or significantly their respective Tribes. At this
point, the FAA has not identified any unique or significant effects,
environmental or otherwise, on tribes resulting from this proposed
rule.

---------------------------------------------------------------------------
C. Executive Order 13211, Regulations That Significantly Affect Energy
Supply, Distribution, or Use
The FAA analyzed this proposed rule under E.O. 13211, Actions
Concerning Regulations that Significantly Affect Energy Supply,
Distribution, or Use (May 18, 2001). The FAA has determined that it
would not be a ``significant energy action'' under the Executive order
and would not be likely to have a significant adverse effect on the
supply, distribution, or use of energy.
D. Executive Order 13609, Promoting International Regulatory
Cooperation
Executive Order 13609, Promoting International Regulatory
Cooperation, promotes international regulatory cooperation to meet
shared challenges involving health, safety, labor, security,
environmental, and other issues and to reduce, eliminate, or prevent
unnecessary differences in regulatory requirements. The FAA has
analyzed this proposed action under the policies and agency
responsibilities of E.O. 13609 and has determined that this proposed
action would have no effect on international regulatory cooperation.
