Abstract
The FAA is superseding Airworthiness Directive (AD) 2023-12-03 and AD 2023-04-05, which applied to certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2023-12-03 and AD 2023-04-05 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 all actions in AD 2023-12-03 and certain actions in AD 2023-04-05, 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.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-12-03
and AD 2023-04-05, which applied to certain Airbus SAS Model A350-941
and -1041 airplanes. AD 2023-12-03 and AD 2023-04-05 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
all actions in AD 2023-12-03 and certain actions in AD 2023-04-05, 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 November 15, 2024.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of November 15,
2024.
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in this AD as of August
7, 2023 (88 FR 42598, July 3, 2023; corrected August 7, 2023 (88 FR
52024)).
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in this AD as of April
10, 2023 (88 FR 13668, March 6, 2023).

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2023-12-03, Amendment 39-22461 (88 FR
42598, July 3, 2023; corrected August 7, 2023 (88 FR 52024)) (AD 2023-
12-03), and AD 2023-04-05, Amendment 39-22352 (88 FR 13668, March 6,
2023) (AD 2023-04-05). AD 2023-12-03 and AD 2023-04-05 applied to
certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2023-12-03
and AD 2023-04-05 required revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive airworthiness limitations. AD 2023-12-03 specified that
accomplishing the revision required by that AD terminated certain
requirements of AD 2023-04-05. The FAA issued AD 2023-12-03 and AD
2023-04-05 to address reduced structural integrity of the airplane.
The NPRM published in the Federal Register on June 26, 2024 (89 FR
53364). The NPRM was prompted by AD 2024-0005, dated January 5, 2024,
issued by EASA, which is the Technical Agent for the Member States of
the European Union (EASA AD 2024-0005) (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 all actions in
AD 2023-12-03 and certain actions in AD 2023-04-05, and to require
revising the existing maintenance or inspection program, as applicable,
to incorporate new or more restrictive airworthiness limitations, as
specified in EASA AD 2024-0005. The FAA is issuing this AD to address
reduced structural integrity of the airplane. The unsafe condition, if
not addressed, could result in loss of structural integrity of the
airplane.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-1694.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from Air Line Pilots Association,
International (ALPA) 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 2024-0005 specifies new or more restrictive airworthiness
limitations for airplane structures and safe life limits.
This AD also requires EASA AD 2023-0004, dated January 6, 2023,
which the Director of the Federal Register approved for incorporation
by reference as of August 7, 2023 (88 FR 42598, July 3, 2023; corrected
August 7, 2023 (88 FR 52024)).
This AD also requires EASA AD 2022-0125, dated June 28, 2022, which
the Director of the Federal Register approved for incorporation by
reference as of April 10, 2023 (88 FR 13668, March 6, 2023).
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 31 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 2023-12-03 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
[[Page 82495]]
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.
