Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus SAS Model Airbus A350-941 and -1041 airplanes. This AD 
was prompted by a determination that the lower attachment studs on the 
aft galley complex may be installed incorrectly due to a missing 
instruction in the maintenance procedure task. This AD requires a one-
time inspection of the lower attachment studs on the aft galley 
complex, and depending on findings, accomplishment of applicable 
corrective actions, as specified in a European Union Aviation Safety 
Agency (EASA) AD, which is incorporated by reference. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective December 31, 2024.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 31, 
2024.

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 Airbus SAS 
Model Airbus A350-941 and -1041 airplanes. The NPRM published in the 
Federal Register on July 17, 2024 (89 FR 58081). The NPRM was prompted 
by AD 2024-0073, dated March 18, 2024, issued by EASA, which is the 
Technical Agent for

[[Page 93153]]

the Member States of the European Union (EASA AD 2024-0073) (also 
referred to as the MCAI). The MCAI states that the maintenance 
procedure task of the galley lower attachment stud installation did not 
provide the required maximum distance between the top of the threaded 
sleeve and the top of the threaded stud, which could lead to a wrong 
installation of the lower attachment stud having part number (P/N) 
XP14-070-007800, P/N XP14-070-019100, P/N XP14-070-005400, P/N XP14-
070-008400, and P/N XP14-070-001100 on the aft galley complex. The MCAI 
also states that the affected parts are the lower attachment stud 
having P/N XP14-070-007800, P/N XP14-070-019100, P/N XP14-070-005400, 
P/N XP14-070-008400, and P/N XP14-070-001100, for which the incomplete 
maintenance procedure task has been accomplished after the airplane 
date of manufacture and before January 2024; and the lower attachment 
stud having P/N XP14-070-019100, which has been installed after the 
airplane date of manufacture and before January 2024, in accordance 
with the instructions of Airbus Alert Operators Transmission A25P023-
22, Revision 01, dated September 27, 2022.
    In the NPRM, the FAA proposed to require a one-time inspection of 
the affected lower attachment studs on the aft galley complex, and 
depending on findings, accomplishment of applicable corrective actions, 
as specified in EASA AD 2024-0073. The FAA is issuing this AD to 
address possible wrong installation for the lower attachment stud 
having P/N XP14-070-007800, P/N XP14-070-019100, P/N XP14-070-005400, 
P/N XP14-070-008400, and P/N XP14-070-001100 on the aft galley complex. 
This condition, if not detected and corrected, could lead to galley 
module detachment, with possible consequent injury to cabin crew and 
passengers, and reduced evacuation capacity from the airplane in case 
of an emergency.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-1888.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from an individual who supported the 
NPRM without change.

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, considered the 
comment 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 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 2024-0073 specifies procedures for a one-time installation 
inspection of the lower attachment stud having P/N XP14-070-007800, P/N 
XP14-070-019100, P/N XP14-070-005400, P/N XP14-070-008400, and P/N 
XP14-070-001100 on the aft galley complex; and depending on findings 
(the distance between the top of the threaded sleeves and the top of 
the threaded studs exceeds specified limits), accomplishment of 
applicable corrective actions (tightening the applicable threaded 
stud(s)). 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 32 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
             Labor cost                Parts cost           Cost per product           Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 3 work-hours x $85 per hour =              $0  Up to $255...................  Up to $8,160.
 $255.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition action that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
airplanes that might need this on-condition action:

                 Estimated Costs of On-Condition Actions

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

[[Page 93154]]

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.
