Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model Airbus A350-941 and A350-1041 airplanes. This proposed 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 proposed AD would require 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 proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2024-0073, dated March 18, 2024
(EASA AD 2024-0073) (also referred to as the MCAI), to correct an
unsafe condition for certain Airbus SAS Model Airbus A350-941 and A350-
1041 airplanes. 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 as previously described
incomplete maintenance procedure task has been accomplished after the
airplane date of manufacture and before January 2024; and the lower
attachment stud 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.
The FAA is proposing this AD to address a possible wrong
installation for 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. 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 <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-1888.
Material Incorporated by Reference Under 1 CFR Part 51
EASA AD 2024-0073 specifies 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 studs).
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.
FAA's Determination
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 is issuing this NPRM after determining that
the unsafe condition described previously is likely to exist or develop
in other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in EASA AD 2024-0073 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA proposes to incorporate EASA AD 2024-0073 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2024-0073 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Using common terms that are the same as the heading
of a particular section in EASA AD 2024-0073 does not mean that
operators need comply only with that section. For example, where the AD
requirement refers to ``all required actions and compliance times,''
compliance with this AD requirement is not limited to the section
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2024-
0073. Material required by EASA AD 2024-0073 for compliance will be
available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2024-1888 after the
FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 32 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed 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
aircraft that might need this on-condition action:
[[Page 58083]]
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
1 work-hour x $85 per hour = $85 per $10 $95
stud adjustment.....................
------------------------------------------------------------------------
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.
