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 <a href="http://regulations.gov">regulations.gov</a> 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
------------------------------------------------------------------------
Cost per
Labor cost Parts cost 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
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.
