AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-20-05 
and AD 2022-09-16, which applied to certain Airbus SAS Model A318 
series; A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, and 
-153N; A320 series; and A321 series airplanes. AD 2020-20-05 and AD 
2022-09-16 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 the actions in AD 2022-09-16, and also requires 
revising the existing maintenance or inspection program, as applicable, 
to incorporate additional 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 September 5, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 5, 
2023

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2020-20-05, Amendment 39-21261 (85 FR 
65197, October 15, 2020) (AD 2020-20-05), and AD 2022-09-16, Amendment 
39-22036 (87 FR 31943, May 26, 2022) (AD 2022-09-16). AD 2020-20-05 and 
AD 2022-09-16 applied to certain Model A318-111, -112, -121, and -122 
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -133, -
151N, and -153N airplanes; Model A320-211, -212, -214, -216, -231, -
232, -233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes; and 
Model -111, -112, -131, -211, -212, -213, -231, -232, -251N, -251NX, -
252N, -252NX, -253N, -253NX, -271N, -271NX, -272N, and -272NX 
airplanes. AD 2020-20-05 and AD 2022-09-16 required revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations. The FAA 
issued AD 2020-20-05 and AD 2022-09-16 to address fatigue cracking, 
accidental damage, or corrosion in principal structural elements, which 
could result in reduced structural integrity of the airplane.
    The NPRM published in the Federal Register on October 20, 2022 (87 
FR 63712). The NPRM was prompted by AD 2022-0085, dated May 12, 2022, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union (EASA AD 2022-0085) (also referred to as the MCAI). 
The MCAI states that new and/or more restrictive maintenance tasks have 
been published.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1296.
    In the NPRM, the FAA proposed to continue to require the actions in 
AD 2022-09-16 and require revising the existing maintenance or 
inspection program, as applicable, to incorporate additional new or 
more restrictive airworthiness limitations, as specified in EASA AD 
2022-0085. The NPRM also proposed to require revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations, as specified in EASA AD 
2021-0140.
    The FAA issued a supplemental notice of proposed rulemaking (SNPRM) 
to amend 14 CFR part 39 to supersede AD 2020-20-05 and AD 2022-09-16.

[[Page 50006]]

The SNPRM published in the Federal Register on March 23, 2023 (88 FR 
17429) (the SNPRM). The SNPRM was prompted by a determination that new 
or more restrictive airworthiness limitations are necessary. In the 
SNPRM, the FAA proposed to continue to require the actions in AD 2022-
09-16 and require revising the existing maintenance or inspection 
program, as applicable, to incorporate additional new or more 
restrictive airworthiness limitations, as specified in EASA AD 2022-
0085. The NPRM also proposed to require revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations, as specified in EASA AD 
2021-0140. The FAA is issuing this AD to address fatigue cracking, 
accidental damage, or corrosion in principal structural elements, which 
could result in reduced structural integrity of the airplane.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from Air Line Pilots Association, 
International (ALPA), who supported the SNPRM without change.
    The FAA received an additional comment from United Airlines. The 
following presents the comment received on the SNPRM and the FAA's 
response.

Request To Allow Airbus Statement of Airworthiness Compliance (ASAC)

    United Airlines requested that the FAA allow Airbus-issued ASACs as 
acceptable means of compliance when they support extensions to the 
compliance time of specified airworthiness limitation section (ALS) 
part 2 tasks.
    The FAA has determined that the requested change is unnecessary 
because the provisions of paragraph (r)(2) permit means of compliance 
approved by Airbus SAS's EASA Design Organization Approval (DOA), 
provided that the approval includes the DOA-authorized signature. This 
AD has not been changed with regard to this request.

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 SNPRM. None of the 
changes will increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2022-0085 and EASA AD 2023-0008. This 
service information specifies new or more restrictive airworthiness 
limitations for airplane structures and safe life limits. These 
documents are distinct since one includes all damage tolerant 
airworthiness limitations items and the other revises certain damage 
tolerant airworthiness limitation items.
    This AD would also require EASA AD 2021-0140, which the Director of 
the Federal Register approved for incorporation by reference as of June 
30, 2022 (87 FR 31943, May 26, 2022).
    This AD would also require EASA AD 2020-0036R1, which the Director 
of the Federal Register approved for incorporation by reference as of 
November 19, 2020 (85 FR 65197, October 15, 2020).
    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 1,864 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 2020-20-05 and AD 2022-09-16 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.
