Airworthiness Directives; The Boeing 

Company Airplanes 

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 

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. 

DATES: The FAA must receive comments 

on this proposed AD by March 3, 2025.

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

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. PSUmounted 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 regulations.gov 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

Action Labor cost Parts cost Cost per monitor Cost on U.S. operators 

Replacement (Burrana monitors—airplanes identified Boeing 

Special Attention Requirements Bulletin 737–25–1851 RB, 

dated December 15, 2023).

2 work-hours × $85 per hour = 

$170, per monitor.

$2,734 ............. $2,904 ............. Up to $5,401,440* 

(62 airplanes). 

Replacement (Panasonic monitors—airplanes identified in 

Boeing Special Attention Requirements Bulletin 737–25– 

1858 RB, dated December 15, 2023).

2 work-hours × $85 per hour = 

$170, per monitor.

$354 ................ $524 ................ Up to $5,376,240* 

(342 airplanes). 

Replacement ..............................................................................

(monitors for airplanes not identified in the Boeing service information).

2 work-hours × $85 per hour = 

$170, per monitor.

Up to $2,734 ... Up to $2,904 ... Up to $4,791,600* 

(55 airplanes). 

*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 

Air transportation, Aircraft, Aviation 

safety, Incorporation by 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:
