 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2025-0003; Project Identifier AD-2024-00110-T]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757-200 and -300 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.
 DATES: The FAA must receive comments on this proposed AD by March 3, 2025.
 ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: *Federal eRulemaking Portal:*

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-2025-0003; Project Identifier AD-2024-00110-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 regulations.gov, 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 St., Des Moines, WA 98198; phone: 206-231-3584; email:

                     Any commentary that the FAA receives that is not 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 757-25-0320 RB and 757-25-0321 RB, both dated January 19, 2024. 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. These documents are distinct since Boeing Special Attention Requirements Bulletin 757-25-0320 RB, dated January 19, 2024, addresses airplanes with certain Burrana monitors, and Boeing Special Attention Requirements Bulletin 757-25-0321 RB, dated January 19, 2024, 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 
                    *regulations.gov*
                     under Docket No. FAA-2025-0003.
                    ( print page 5755) Difference Between This Proposed AD and the Referenced Material The effectivity in Boeing Special Attention Requirements Bulletin 757-25-0320 RB, and Boeing Special Attention Requirements Bulletin 757-25-0321 RB, both dated January 19, 2024, 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 757-200 and -300 series model 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 85 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: Estimated Costs

 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.

 The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES
 1.The authority citation for part 39 continues to read as follows: Authority:
                    49 U.S.C. 106(g), 40113, 44701. § 39.13
 2.The FAA amends § 39.13 by adding the following new airworthiness directive: **The Boeing Company:**
