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 certain The Boeing
Company Model 737-600, -700, -700C, -800, -900, and -900ER series
airplanes. The NPRM was published in the Federal Register on January
17, 2025 (90 FR 5751). The NPRM was prompted by a report that some PSU-
mounted video monitors became detached from the PSU rails during a hard
landing that did not exceed the emergency load requirements for the
PSUs. In the NPRM, the FAA proposed to require replacing PSU-mounted
video monitors that do not have secondary retention lanyards. The FAA
is issuing this AD to address PSU-mounted video monitors that could
become fully detached or be held at an unsafe height, which, if not
addressed, could result in injury to passengers and impede passenger
and crew egress during emergency evacuation.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from Boeing, who supported the NPRM
without change.
The FAA received additional comments from five commenters,
including All Nippon Airways Co., Ltd. (ANA), Aviation Partners Boeing,
Delta Air Lines, Inc. (Delta), Panasonic Avionics Corporation
(Panasonic), and an individual. The following presents the comments
received on the NPRM and the FAA's response to each comment.
Request To Clarify Method for Determining Applicability
Delta requested that the FAA clarify that they can accomplish
either a physical inspection for the existence of PSU-mounted video
monitors or accomplish a review of Delta's PSU Layouts (Delta's PSU
drawing configuration) to determine if this AD applies.
The FAA agrees to clarify that operators can determine if their
airplanes are equipped with PSU-mounted video monitors by performing a
physical inspection or a records check, provided the presence of PSU-
mounted video monitors can be conclusively
[[Page 65942]]
determined from that review; either method is acceptable to determine
if this AD applies. The FAA did not change this AD in response to this
comment.
Effect of Winglets on Accomplishment of the Proposed Actions
Aviation Partners Boeing stated that the installation of blended or
split scimitar winglets per supplemental type certificate (STC)
ST00830SE does not affect compliance with the mandated actions in the
proposed rule.
The FAA agrees with the commenter that STC ST00830SE does not
affect compliance with this AD. Therefore, the installation of STC
ST00830SE does not affect the ability to accomplish the actions
required by this AD. The FAA did not change this AD in response to this
comment.
Request To Revise Paragraph (e) To Clarify Safety Concerns
Panasonic requested that the FAA revise paragraph (e) of the
proposed AD to include the statement, ``Although some models of PSU-
mounted video monitors have not become detached under such landings, we
have determined that this AD is warranted due to relative motion
between the PSU rails that drive forces exceeding the approved
emergency landing conditions for the attached PSU-mounted monitors.''
Panasonic asserted that the improvement action for Panasonic monitors
involves an enhancement to its fail-safe design and is not a result of
correcting any defect or noncompliance in the PSU-mounted monitor
assemblies themselves. Panasonic requested this change to avoid
potentially misleading operators that Panasonic monitors have become
detached because they did not meet the existing emergency landing
requirements they were designed to meet.
The FAA acknowledges the commenter's concern. The FAA is unaware of
Panasonic monitors that have become detached during hard landings that
did not exceed emergency landing requirements. However, paragraph (e)
of this AD specifies that some, not all, PSU-mounted video monitors
became detached. The FAA did not change this AD in response to this
comment.
Request To Include Panasonic Service Bulletin SB141908-44-001 as an
Accepted Method of Compliance
Panasonic requested that the FAA include Panasonic Service Bulletin
SB141908-44-001 as an accepted method of compliance for the proposed AD
but did not provide the specified service bulletin to the FAA.
Panasonic asserted that the effectivity of Boeing Special Attention
Requirements Bulletin 737-25-1858 RB does not include airplanes with
STCs that have identical parts that would be affected by the NPRM and
suggested that adding this service bulletin as an accepted method of
compliance would reduce the FAA's efforts to support alternative
methods of compliance (AMOC) requests to address airplanes installed
with FAA STC ST02908NY.
The FAA disagrees. Paragraph (g)(3) of this AD requires airplanes
not identified in the effectivity paragraph of either Boeing service
bulletin to perform the required actions using an AMOC. At this time,
the FAA does not have enough data to approve Panasonic Service Bulletin
SB141908-44-001 as an accepted method of compliance for this AD. The
FAA did not change this AD in response to this comment.
Requests To Refer to Later Revisions of the Service Information
ANA requested that the FAA update the service information
referenced in the proposed AD. The commenter noted that Boeing Special
Attention Requirements Bulletin 737-25-1851 RB, dated December 15,
2023, and Boeing Special Attention Requirements Bulletin 737-25-1858
RB, dated December 15, 2023, will be revised by Boeing to correct an
error in the airplane effectivity and asked the FAA to include the
revised service information in the AD when published.
Delta requested that the FAA add the latest revisions of the
Panasonic Service Bulletins referenced in Boeing Special Attention
Requirements Bulletin 737-25-1858 RB, dated December 15, 2023, as a
method of compliance for the proposed AD. Delta stated that Boeing
released a preliminary revision of the requirements bulletin that
references the latest revisions of the Panasonic Service Bulletins.
An individual noted that there are later revisions of the Burrana
Service Bulletins referenced in Boeing Special Attention Requirements
Bulletin 737-25-1851 RB, dated December 15, 2023. The commenter did not
make a specific request for FAA action.
The FAA agrees to use the latest service information in this AD.
Boeing Special Attention Requirements Bulletin 737-25-1851 RB, Revision
1, dated July 15, 2025, and Boeing Special Attention Requirements
Bulletin 737-25-1858 RB, Revision 1, dated July 15, 2025, add
instructions for installing lanyard retention brackets at locations
where there are no holes in the PSU inboard rail and at locations with
oval-shaped holes for airplanes without a Boeing Sky Interior (BSI) in
groups 1 and 2. The revised service information removes from the
effectivity Model 737-800 airplanes that have been modified to a Boeing
Converted Freighter; this information does not affect the applicability
of this AD. The revised service information specifies later revisions
of the Burrana and Panasonic service bulletins, as applicable. Boeing
Special Attention Requirements Bulletin 737-25-1858 RB, Revision 1,
dated July 15, 2025, specifies an additional inspection for airplanes
in groups 1 and 2 that have a PSU-mounted video monitor installed at a
cabin temperature sensor location and have accomplished the original
issue of the service information, because the original issue could not
be complied with to address the unsafe condition. Boeing Special
Attention Requirements Bulletin 737-25-1858 RB, Revision 1, dated July
15, 2025, also specifies credit for accomplishing the original issue of
the service information for airplanes in groups 3 and 4.
The FAA has revised this AD to mandate Boeing Special Attention
Requirements Bulletin 737-25-1851 RB, Revision 1, dated July 15, 2025,
and Boeing Special Attention Requirements Bulletin 737-25-1858 RB,
Revision 1, dated July 15, 2025. The FAA has revised paragraph (i)(1)
of this AD to add credit for previous actions for airplanes that
completed Boeing Special Attention Requirements Bulletin 737-25-1851
RB, dated December 15, 2023, and redesignated subsequent paragraphs
accordingly. The FAA also added paragraph (i)(2) of this AD to add
credit for previous actions for airplanes that completed Boeing Special
Attention Requirements Bulletin 737-25-1858 RB, dated December 15,
2023, for airplanes identified as groups 3 and 4 only.
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.

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.
