Accomplishment Instructions or figures that 

are labeled as RC, the instructions in RC 

steps, including subparagraphs under an RC 

step and any figures identified in an RC step, 

must be done to comply with this AD; any 

steps including substeps under those steps, 

that are not identified as RC are 

recommended. The instructions in steps, 

including substeps under those steps, not 

identified as RC may be deviated from using 

accepted methods in accordance with the 

operator’s maintenance or inspection 

program without obtaining approval of an 

AMOC, provided the instructions identified 

as RC can be done and the airplane can be 

put back in an airworthy condition. Any 

substitutions or changes to instructions 

identified as RC require approval of an 

AMOC. If a step or substep is labeled ‘‘RC 

Exempt,’’ then the RC requirement is 

removed from that step or substep.

SUPPLEMENTARY INFORMATION: 


lotter on DSK11XQN23PROD with RULES1
84802 Federal Register / Vol. 89, No. 206 / Thursday, October 24, 2024 / Rules and Regulations 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2023–07–13, 

Amendment 39–22415 (88 FR 31169, 

May 16, 2023) (AD 2023–07–13). AD 

2023–07–13 applied to certain Airbus 

SAS Model A350–941 and –1041 

airplanes. AD 2023–07–13 required 

repetitive detailed inspections of the 

lower attachment studs on the AFT 

galley complex for damage (i.e., stress 

marks, dents, bumps, corrosion, 

contamination, cracks, and scratches) 

and correct installation and, depending 

on findings, replacement of the lower 

attachment stud. The FAA issued AD 

2023–07–13 to address broken lower 

attachment studs having Part Number 

(P/N) XP14–070–007800 on the AFT 

galley complex. 

The NPRM published in the Federal 

Register on July 23, 2024 (89 FR 59709). 

The NPRM was prompted by AD 2024– 

0078, dated March 20, 2024, issued by 

EASA, which is the Technical Agent for 

the Member States of the European 

Union (EASA AD 2024–0078) (also 

referred to as the MCAI). The MCAI 

states that additional airplanes are 

affected, and that all lower attachment 

studs having P/N XP14–070–007800, on 

the AFT galley complex must be 

replaced. Broken lower attachment 

studs on the AFT galley complex, if not 

addressed, could lead to galley 

detachment, resulting in injury to 

airplane occupants and reduced 

capacity for emergency evacuation of 

the airplane. 

In the NPRM, the FAA proposed to 

continue to require the actions in AD 

2023–07–13, add airplanes to the 

applicability, and require the 

replacement of all affected parts, as 

specified in EASA AD 2024–0078. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–1892. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the cost to the public. 

Conclusion 

This product has been approved by 

the aviation authority of another 

country and is approved for operation in 

the United States. Pursuant to the FAA’s 

bilateral agreement with this State of 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI referenced above. The FAA 

reviewed the relevant data and 

determined that air safety requires 

adopting this AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on this 

product. 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 

EASA AD 2024–0078 specifies 

repetitive detailed inspections for 

damaged and incorrectly installed lower 

attachment studs having P/N XP14– 

070–007800 on the AFT galley complex 

and, depending on findings, 

replacement of the lower attachment 

studs, and eventual replacement of all 

affected lower attachment studs having 

P/N XP14–070–007800. EASA AD 

2024–0078 specifies that replacement of 

all lower attachment studs having P/N 

XP14–070–007800 on all affected AFT 

galleys constitutes a terminating action 

for the repetitive detailed inspections. 

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 13 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Retained actions from AD 2023–07–13 ............. 2 work-hours × $85 per hour = $170 ................. $0 $170 $2,210 

New actions ........................................................ 7 work-hours × $85 per hour = $595 ................. 95 690 8,970 

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.

and intervals for life-limited parts. This 

AD requires revising the airworthiness 

limitations section (ALS) of the 

operator’s existing approved engine 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive instructions and associated 

thresholds and intervals for life-limited 

parts, as specified in a European Union 

Aviation Safety Agency (EASA) AD, 

which is incorporated by reference 

(IBR). The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective November 8, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 8, 2024. 

The FAA must receive comments on 

this AD by December 9, 2024.
