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.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed Boeing Special Attention Requirements Bulletin 
737-25-1851 RB, Revision 1, dated July 15, 2025. This material 
specifies procedures

[[Page 65943]]

for replacing certain Burrana PSU-mounted video monitors that do not 
have secondary retention lanyards with PSU-mounted video monitors that 
have secondary retention lanyards.
    The FAA also reviewed Boeing Special Attention Requirements 
Bulletin 737-25-1858 RB, Revision 1, dated July 15, 2025. This material 
specifies procedures for replacing certain Panasonic PSU-mounted video 
monitors that do not have secondary retention lanyards with PSU-mounted 
video monitors that have secondary retention lanyards. This material 
specifies an additional inspection of the inboard PSU rail and 
applicable on-condition actions 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. On-condition actions include attaching the secondary 
retention lanyard torsion spring to either the 1-inch hole found during 
inspection or the retention backet, as necessary.
    This material is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

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.
