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 A350-941 and -1041 airplanes. This AD was 
prompted by reports of broken lower attachment studs on the AFT galley 
complex. This AD requires repetitive detailed inspections of the lower 
attachment studs and, depending on findings, replacement of the lower 
attachment studs, 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 June 20, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 20, 
2023.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under

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 A350-941 and -1041 airplanes. The NPRM published in the Federal 
Register on January 12, 2023 (88 FR 2032). The NPRM was prompted by AD 
2022-0196, dated September 20, 2022, issued by EASA, which is the 
Technical Agent for the Member States of the European Union (EASA AD 
2022-0196) (also referred to as the MCAI). The MCAI states that the 
manufacturer has received reports of broken lower attachment studs on 
the AFT galley complex. The manufacturer's investigation indicates that 
the broken lower attachment studs resulted from a hydrogen-induced 
failure. This condition, 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 require repetitive detailed 
inspections of the lower attachment studs and, depending on findings, 
replacement of the lower attachment studs, as specified in EASA AD 
2022-0196. 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-2022-1659.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from Air Line Pilots Association, 
International, who supported the NPRM without change.
    The FAA received an additional comment from Delta Air Lines (DAL). 
The following presents the comment received on the NPRM and the FAA's 
response.

Request for Clarification of Reporting Requirements

    DAL requested clarification of the reporting requirements in the 
NPRM. DAL noted that the Airbus Alert

[[Page 31170]]

Operators Transmission (AOT) referenced by EASA AD 2022-0196 addresses 
reporting of inspection results (with or without finding) to Airbus 
Customer Services. DAL proposed that the FAA AD verify that this 
reporting requirement is not mandated.
    The FAA agrees to clarify. As specified in paragraph (i)(3) of this 
AD, if any service information contains paragraphs that are identified 
as RC (required for compliance), those paragraphs must be done to 
comply with this AD; any paragraphs that are not identified as RC are 
recommended. The reporting paragraph in the Airbus AOT referenced in 
EASA AD 2022-0196 is not labeled as RC; therefore, reporting is not 
required for compliance in this AD. The FAA has not changed this AD as 
a result of this comment.

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 
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.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0196 specifies procedures for repetitive detailed 
inspections for broken lower attachment studs and, depending on 
findings, replacement of the lower attachment studs on the AFT galley 
complex. The MCAI specifies that replacement of the lower attachment 
studs on the AFT galley complex constitutes a terminating action for 
the repetitive detailed inspections. The MCAI also prohibits the 
installation of affected parts on any airplane. 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.

Interim Action

    The FAA considers that this AD is an interim action. If final 
action is later identified, the FAA may consider further rulemaking.

Costs of Compliance

    The FAA estimates that this AD affects 8 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170...........................              $0             $170           $1,360
----------------------------------------------------------------------------------------------------------------

    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:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
7 work-hours x $85 per hour = $595....             $95             $690
------------------------------------------------------------------------

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.
