SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all The Boeing Company
Model 767-300F airplanes. The NPRM published in the Federal Register on
December 9, 2022 (87 FR 75519). The NPRM was prompted by a non-
compliance report indicating that the technical standard order
installation requirements for the first observer seat in the flight
deck were not followed. When the first observer seat, located in front
of the supernumerary seats, is in the furthest aft position on the seat
tracks, the ``head path stay out zone'' is compromised. In the NPRM,
the FAA proposed to require installing placards in various locations of
the flight deck to indicate the proper position for the first observer
seat during taxi, takeoff, and landing, and revising the existing AFM.
The FAA is issuing this AD to address the unsafe condition, which could
result in occupants seated in the right or center supernumerary seats
sustaining an injury during an emergency landing.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from the Air Line Pilots Association,
International (ALPA), and The Boeing Company who supported the NPRM
without change.
The FAA received additional comments from Aviation Partners Boeing,
Federal Express (FedEx), and United Parcel Service (UPS). The following
presents the comments received on the NPRM and the FAA's response to
each comment.
Effect of Winglets on Accomplishment of the Proposed Actions
Aviation Partners Boeing stated that the installation of winglets
per Supplemental Type Certificate (STC) ST01920SE on applicable Boeing
models subject to the proposed rule does not affect compliance with the
mandated actions in this AD.
The FAA agrees with the commenter that STC ST01920SE does not
affect the ability to accomplish the actions required by this AD. The
FAA has not changed this AD in this regard.
Request To Allow Installation of Equivalent Placards
FedEx stated that Boeing Special Attention Requirements Bulletin
767-25-0589 RB, dated February 25, 2022, currently specifies the
installation of Boeing placard part numbers BAC27TFDE714 and
BAC27TFDE715. FedEx requested that the proposed AD be revised to allow
installation of equivalent placards with like verbiage in lieu of the
Boeing part numbers.
The FAA disagrees with the request because the placard verbiage,
font, color and locations are standard and they follow the
certification requirements. Although, it is not acceptable to change
the verbiage, an alternative method of compliance (AMOC) request may be
submitted with supporting data that demonstrates an acceptable level of
safety for equivalent placards. The FAA has not changed this AD in this
regard.
Request To Change Instructions for Placard Installation
FedEx requested that the AD allow measuring both the horizontal and
vertical dimensions from the same corner that currently only the
vertical dimension is measured from, as specified in the Boeing Special
Attention Requirements Bulletin 767-25-0589 RB, dated February 25,
2022. FedEx additionally wanted the dimension tolerances increased to a
minimum of 0.25''/1.50'' for workability, as these position tolerances
do not affect safety or the ability of the placard to communicate
safety information to the crew.
The FAA disagrees with the requested method of measurement as it
does not comply with the information specified in Boeing Special
Attention Requirements Bulletin 767-25-0589 RB, dated February 25,
2022. Operators may submit requests for approval of AMOCs with
supporting data that demonstrates an acceptable level of safety for an
alternative method of measurement and
[[Page 44036]]
deviation to the dimensional tolerances specified in Boeing Special
Attention Requirements Bulletin 767-25-0589 RB, dated February 25,
2022. The FAA has not changed this AD in this regard.
Request To Change Applicability Statement
UPS requested that the paragraph (c) of the proposed AD be updated
to state that the AD is limited to Model 767-300F airplanes identified
in Boeing Special Attention Requirements Bulletin 767-25-0589 RB, dated
February 25, 2022, instead of stating that all Model 767-300F airplanes
are affected.
The FAA agrees with the comment because the manufacturer has
incorporated the placards on line numbers 1208 and subsequent in
production. Therefore, the affected airplane line numbers are listed in
Boeing Special Attention Requirements Bulletin 767-25-0589 RB, dated
February 25, 2022. Paragraph (c) of this AD has been updated
accordingly.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting this AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. Except for minor editorial changes, and
any other changes described previously, this AD is adopted as proposed
in the NPRM. None of the changes will increase the economic burden on
any operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Special Attention Requirements Bulletin
767-25-0589 RB, dated February 25, 2022. This service information
specifies procedures for installing markers (placards) in the flight
deck regarding the position of the first observer seat position during
taxi, takeoff, and landing.
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in ADDRESSES.
Compliance With AFM Revisions
Section 91.9 prohibits any person from operating a civil aircraft
without complying with the operating limitations specified in the AFM
and on installed placards. FAA regulations also require operators to
furnish pilots with any changes to the AFM (14 CFR 121.137) and pilots
in command to be familiar with the AFM and installed placards
containing operating limitations (14 CFR 91.505).
Costs of Compliance
The FAA estimates that this AD affects 153 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Placard installation........... 1 work-hour x $85 per Up to $117....... Up to $202....... Up to $30,906.
hour = $85.
AFM revision................... 1 work-hour x $85 per 0................ $85.............. $13,005.
hour = $85.
----------------------------------------------------------------------------------------------------------------
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.
Regulatory Findings
This AD will not have federalism implications under Executive Order
13132. This AD will not have a substantial direct effect 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.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
