Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2022-22-
10, which applied to certain Airbus SAS Model A318, A319, A320, and 
A321 series airplanes. AD 2022-22-10 required revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations. This AD was prompted by a 
determination that new or more restrictive airworthiness limitations 
are necessary. This AD continues to require certain actions in AD 2022-
22-10 and requires revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations, 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 March 17, 2025.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 17, 
2025.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
December 30, 2022 (87 FR 72374, November 25, 2022).

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2024-2323; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2022-22-10, Amendment 39-22225 (87 FR 
72374, November 25, 2022) (AD 2022-22-10). AD 2022-22-10 applied to 
certain Airbus SAS Model A318, A319, A320, and A321 series airplanes. 
AD 2022-22-10 required revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations. The FAA issued AD 2022-22-10 to address 
failure of certain life-limited parts, which could result in reduced 
structural integrity of the airplane.
    The NPRM published in the Federal Register on October 1, 2024 (89 
FR 79789). The NPRM was prompted by AD 2024-0066, dated March 8, 2024, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union (EASA AD 2024-0066) (also referred to as the MCAI). 
The MCAI states that new or more restrictive airworthiness limitations 
have been developed.
    In the NPRM, the FAA proposed to continue to require certain 
requirements of AD 2022-22-10. The FAA also proposed to require 
revising the existing maintenance or inspection program, as applicable, 
to incorporate additional new or more restrictive airworthiness 
limitations, as specified in EASA AD 2024-0066. The FAA is issuing this 
AD to address failure of certain life-limited parts, which could result 
in reduced structural integrity of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-2323.

Discussion of Final Airworthiness Directive

Comments

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

Change Made to This AD

    The FAA revised paragraph (m) of this AD to specify that previously 
approved AMOCs for AD 2022-22-10 are approved as AMOCs for the 
corresponding provisions of EASA AD 2022-0082, dated May 10, 2022 (EASA 
AD 2022-0082), which are required by paragraph (g) of this AD, and the 
corresponding provisions of EASA AD 2024-0066, which are required by 
paragraph (j) of this AD.

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, 
and any other changes described previously, 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 2024-0066 specifies new or more restrictive airworthiness 
tasks and limitations for airplane structures and safe life limits.
    This AD also requires EASA AD 2022-0082, which the Director of the 
Federal Register approved for incorporation by reference as of December 
30, 2022 (87 FR 72374, November 25, 2022).
    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 1,857 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2022-22-10 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate.
    The FAA estimates the total cost per operator for the new actions 
to be $7,650 (90 work-hours x $85 per work-hour).

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.
