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 all 
Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by 
a determination that certain master minimum equipment list (MMEL) items 
do not comply with MMEL certification requirements. This AD requires 
revising the operator's existing FAA-approved minimum equipment list 
(MEL), 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 July 2, 2025.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 2, 
2025.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2025-0335; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains this final rule, the mandatory continuing airworthiness 
information (MCAI), any comments received, and other information. The 
address for Docket Operations is U.S. Department of Transportation,

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 all Airbus SAS Model 
A350-941 and -1041 airplanes. The NPRM was published in the Federal 
Register on March 5, 2025 (90 FR 11236). The NPRM was prompted by AD 
2024-0157, dated August 14, 2024, issued by EASA, which is the 
Technical Agent for the Member States of the European Union (EASA AD 
2024-0157) (also referred to as the MCAI). The MCAI states that certain 
MMEL items do not comply with MMEL certification requirements.
    In the NPRM, the FAA proposed to require revising the operator's 
existing FAA-approved MEL, as specified in EASA AD 2024-0157. The FAA 
is issuing this AD to address certain MMEL items that do not comply 
with MMEL certification requirements. This condition, if not corrected, 
could result in reduced controllability of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2025-0335.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from the Air Line Pilots Association, 
International (ALPA) and ProTech Aero Services Limited (ProTech) who 
supported the NPRM without change.

Conclusion

    These products have been approved by the civil aviation authority 
of another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with this State of Design 
Authority, that authority has notified the FAA of the unsafe condition 
described in the MCAI referenced above. 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 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

    The FAA reviewed EASA AD 2024-0157. This material specifies 
procedures for revising the operator's MEL by incorporating the 
information in MMEL item numbers 32-42-13 ``Remote Brake Control Unit 
Channel A,'' 32-51-01 ``Steering Control,'' 27-14-01 ``Outer Aileron 
Green Hydraulic Actuator,'' 27-14-02 ``Outer Aileron Yellow Hydraulic 
Actuator,'' 27-14-03 ``Outer Aileron Pressure Sensor,'' and 32-41-02 
``Main Wheel Tie Bolt,'' as applicable. 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 36 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
----------------------------------------------------------------------------------------------------------------
10 work-hours x $85 per hour = $850...........                 $0                $850                   $30,600

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.
