SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2020-22-16, Amendment 39-21312 (85 FR 
70439, November 5, 2020) (AD 2020-22-16), AD 2021-16-01, Amendment 39-
21662 (86 FR 47212, August 24, 2021) (AD 2021-16-01), and AD 2022-04-
03, Amendment 39-21944 (87 FR 10064, February 23, 2022) (AD 2022-04-
03). AD 2020-22-16, AD 2021-16-01, and AD 2022-04-03 applied to certain 
Airbus SAS Model A318, A320, and A321 series airplanes; and Model A319-
111, -112, -113, -114, -115, -131, -132, -133, -151N, and -153N 
airplanes. AD 2020-22-16, AD 2021-16-01, and AD 2022-04-03 required 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations. AD 
2021-16-01 specified that accomplishing the revision required by that 
AD terminates the corresponding requirements of AD 2020-22-16, for the 
tasks identified in the service information referred to in EASA AD 
2020-0219, dated October 12, 2020, only. AD 2022-04-03 specified that 
accomplishing the revision required by that AD terminates the 
limitations of Task 262300-00001-1-C, as required by paragraph (i) of 
AD 2020-22-16, for airplanes with an original airworthiness certificate 
or original export certificate of airworthiness issued on or before 
January 17, 2020 only. The FAA issued AD 2020-22-16, AD 2021-16-01, and 
AD 2022-04-03 to address safety-significant latent failure (that is not 
annunciated), which, in combination with one or more other specific 
failures or events, could result in a hazardous or catastrophic failure 
condition.
    The NPRM published in the Federal Register on December 6, 2022 (87 
FR 74530). The NPRM was prompted by AD 2022-0091, dated May 20, 2022, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union (EASA AD 2022-0091) (referred to after this as the 
MCAI). The MCAI states that new or more restrictive airworthiness 
limitations have been

[[Page 13666]]

developed to address the unsafe condition on these products.
    In the NPRM, the FAA proposed to continue to require the actions in 
AD 2020-22-16, AD 2021-16-01, and AD 2022-04-03. The NPRM 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 2022-0091. The FAA 
is issuing this AD to address a safety significant latent failure (that 
is not annunciated), which, in combination with one or more other 
specific failures or events, could result in a hazardous or 
catastrophic failure condition.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1573.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from the 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.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2022-0091, which specifies new or more 
restrictive airworthiness limitations for certification maintenance 
requirements.
    This AD requires EASA AD 2020-0067, dated March 23, 2020; which the 
Director of the Federal Register approved for incorporation by 
reference as of December 10, 2020 (85 FR 70439, November 5, 2020).
    This AD requires EASA AD 2020-0219, dated October 12, 2020, which 
the Director of the Federal Register approved for incorporation by 
reference as of September 28, 2021 (86 FR 47212, August 24, 2021).
    This AD also requires EASA AD 2021-0108, dated April 20, 2021, 
which the Director of the Federal Register approved for incorporation 
by reference as of March 30, 2022 (87 FR 10064, February 23, 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 ADDRESSES.

Costs of Compliance

    The FAA estimates that this AD affects 1,680 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 2020-22-16, AD 2021-16-01, and AD 2022-04-03 to be 
$7,650 (90 work-hours x $85 per work-hour) per AD.
    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

    The FAA has determined that 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.
