Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and 900ER series airplanes. This proposed AD was prompted by a report that some passenger service unit (PSU)-mounted video monitors became detached from the PSU rails during a hard landing. This proposed AD would require replacing PSU-mounted video monitors that do not have secondary retention lanyards. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------

for certain The Boeing Company Model 737-600, -700, -700C, -800, -900,
and 900ER series airplanes. This proposed AD was prompted by a report
that some passenger service unit (PSU)-mounted video monitors became

SUPPLEMENTARY INFORMATION:
Comments Invited
The FAA invites you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under ADDRESSES. Include ``Docket No. FAA-2025-0004; Project Identifier
AD-2024-00094-T'' at the beginning of your comments. The most helpful
comments reference a specific portion of the proposal, explain the
reason for any recommended change, and include supporting data. The FAA
will consider all comments received by the closing date and may amend
this proposal because of those comments.
Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
<a href="http://regulations.gov">regulations.gov</a>, including any personal information you provide. The
agency will also post a report summarizing each substantive verbal
contact received about this NPRM.
Confidential Business Information
CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this NPRM contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this NPRM. Submissions containing CBI should be sent to Julie
Linn, Aviation Safety Engineer, FAA, 2200 South 216th
[[Page 5752]]

specifically designated as CBI will be placed in the public docket for
this rulemaking.
Background
The FAA has received 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. PSU-mounted video
monitors that become fully detached or are held at an unsafe height
could result in injury to passengers and impede passenger and crew
egress during emergency evacuation.
FAA's Determination
The FAA is issuing this NPRM after determining that the unsafe
condition described previously is likely to exist or develop on other
products of the same type design.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed Boeing Special Attention Requirements Bulletins
737-25-1851 RB and 737-25-1858 RB, both dated December 15, 2023. This
material specifies procedures for replacing all PSU-mounted video
monitors that do not have secondary retention lanyards with PSU-mounted
video monitors that have secondary retention lanyards. The replacement
includes making sure each inboard lanyard is attached to the inboard
PSU rail. These documents are distinct since Boeing Special Attention
Requirements Bulletin 737-25-1851 RB, dated December 15, 2023,
addresses airplanes with certain Burrana monitors, and Boeing Special
Attention Requirements Bulletin 737-25-1858 RB, dated December 15,
2023, addresses airplanes with certain Panasonic monitors. 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 ADDRESSES.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the material already described, except for any differences
identified as exceptions in the regulatory text of this proposed AD,
and except as described under ``Difference Between this Proposed AD and
the Referenced Material.'' For information on the procedures and
compliance times, see this material at <a href="http://regulations.gov">regulations.gov</a> under Docket No.
FAA-2025-0004.
Difference Between This Proposed AD and the Referenced Material
The effectivity in Boeing Special Attention Requirements Bulletin
737-25-1851 RB, and Boeing Special Attention Requirements Bulletin 737-
25-1858 RB, both dated December 15, 2023, is limited to certain line
numbers, which address PSU-mounted video monitors installed in
production. However, affected PSU-mounted video monitors may also be
installed on airplanes modified in accordance with a supplemental type
certificate. The applicability of this proposed AD, therefore, is
expanded to specify The Boeing Company Model 737-600, -700, -700C, -
800, -900, and -900ER series airplanes equipped with PSU-mounted video
monitors to ensure that the unsafe condition is adequately addressed in
the fleet.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 459 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per monitor operators

*An airplane may have up to 30 monitors.
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
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39

reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
