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 737–300, –400, and –800 series 

airplanes. The NPRM published in the 

Federal Register on June 24, 2024 (89 

FR 52408). The NPRM was prompted by 

a report that the protective spiral wrap 

used on certain galley wire bundles 

does not have the correct flammability 

properties and may not self-extinguish. 

In the NPRM, the FAA proposed to 

require inspecting certain galleys to 

determine part numbers, inspecting for 

an existing galley modification placard 

and marking on galleys with affected 

part numbers, and replacing wire 

bundle spiral wrap sleeving as 

applicable; and to prohibit the 

installation of affected parts. The FAA 

is issuing this AD to address the 

incorrect flammability properties, 

which, if not addressed, could result in 

electrical arcing or sparking, ignition of 

the spiral wire wrapping, and smoke 

and/or fire in the flight compartment, 

leading to loss of continued safe flight 

and landing. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from the 

Air Line Pilots Association, who 

supported the NPRM without change. 

The FAA received additional 

comments from Aviation Partners 

Boeing. The following presents the 

comments received on the NPRM and 

the FAA’s response to each comment. 

Effect of Winglets on Accomplishment 

of the Proposed Actions 

Aviation Partners Boeing stated that 

the installation of winglets per 

Supplemental Type Certificate (STC) 

ST00830SE and STC ST01219SE does 

not affect the accomplishment of the 

manufacturer’s service instructions. 

The FAA agrees with the commenter 

that STC ST00830SE and STC 

ST01219SE do not affect the 

accomplishment of the manufacturer’s 

service instructions. Therefore, the 

installation of STC ST00830SE and STC 

ST01219SE does not affect the ability to 

accomplish the actions required by this 

AD. The FAA has not changed this AD 

in this regard. 

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, 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 Alert 

Requirements Bulletin 737–25A1873 

RB, dated August 25, 2023; and Boeing 

Alert Requirements Bulletin 737– 

25A1876 RB, dated September 1, 2023. 

This material specifies procedures for 

an inspection or records check to 

determine the part number of certain 

galleys; and for any galley with an 

affected part number found, an 

inspection for an existing galley 

modification placard and any marking 

indicating the galley was modified using 

certain service information; and, if 

applicable, replacement of wire bundle 

polyethylene protective spiral wrap 

protective sleeving with Boeing Material 

Specification (BMS) 13–81 wire 

protective sleeving. These documents 

are distinct since they apply to different 

airplane models. 

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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 4 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection for galley part number ................... 1 work-hour × $85 per hour = $85 ................. $0 $85 $340 

The FAA estimates the following 

costs to do any necessary inspections or 

replacements that would be required 

based on the results of the inspection. 

The agency has no way of determining 

the number of aircraft that might need 

these inspections or replacements: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per product 

Inspection for modification placard 1 work-hour × $85 per hour = $85 $0 .................................................. $85.

Replacement .................................. Up to 218 work-hours × $85 per 

hour = $18,530.

Up to $1,185 ................................. Up to $19,715. 

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.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2023–02–08, 

Amendment 39–22315 (88 FR 7867, 

February 7, 2023) (AD 2023–02–08). AD 

2023–02–08 applied to certain ATR–GIE 

Avions de Transport Re ́gional Model 

ATR42–500 airplanes. AD 2023–02–08 

required revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

The FAA issued AD 2023–02–08 to 

prevent reduced structural integrity of 

the airplane. 

The NPRM published in the Federal 

Register on June 13, 2024 (89 FR 50241). 

The NPRM was prompted by AD 2024– 

0052, dated February 23, 2024, issued 

by EASA, which is the Technical Agent 

for the Member States of the European 

Union (EASA AD 2024–0052) (also 

referred to as the MCAI). The MCAI 

states that new or more restrictive 

airworthiness limitations have been 

developed. 

In the NPRM, the FAA proposed to 

retain the requirements of AD 2023–02– 

08. The NPRM also proposed to require 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations, as specified 

in EASA AD 2024–0052. The FAA is 

issuing this AD to address among other 

things, fatigue cracking and damage in 

principal structural elements. The 

unsafe condition, if not addressed, 

could result in reduced structural 

integrity of the airplane. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–1482.
