Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-21-
10, which 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; and AD 2022-07-08, which applied 
to all Airbus SAS Model A318, A319, A320 and A321 series airplanes. AD 
2020-21-10 and AD 2022-07-08 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 2020-21-
10 and AD 2022-07-08 and 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 April 18, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 18, 
2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of May 
19, 2022 (87 FR 22117, April 14, 2022).
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
November 19, 2020 (85 FR 65190, October 15, 2020).

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2020-21-10, Amendment 39-21283 (85 FR 
65190,

[[Page 15601]]

October 15, 2020) (AD 2020-21-10) and AD 2022-07-08, Amendment 39-21996 
(87 FR 22117, April 14, 2022) (AD 2022-07-08).
    AD 2020-21-10 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 2020-21-10 required 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations. The 
FAA issued AD 2020-21-10 to address the risks associated with the 
effects of aging on airplane systems. Such effects could change system 
characteristics, leading to an increased potential for failure of 
certain life-limited parts, and reduced structural integrity or 
controllability of the airplane.
    AD 2022-07-08 applied to all Airbus SAS Model A318, A319, A320, and 
A321 series airplanes. AD 2022-07-08 required inspections of certain 
trimmable horizontal stabilizer actuators (THSAs) and replacement if 
necessary, and revising the existing maintenance or inspection program, 
as applicable, to incorporate new or more restrictive airworthiness 
limitations. The FAA issued AD 2022-07-08 to address premature wear of 
the carbon friction disks on the no-back brake of the THSA, which could 
lead to reduced braking efficiency in certain load conditions, and, in 
conjunction with the inability of the power gear train to keep the ball 
screw in its last commanded position, could result in uncommanded 
movements of the trimmable horizontal stabilizer and loss of control of 
the airplane. AD 2022-07-08 also specified that accomplishing the 
revision required by that AD terminates certain requirements of AD 
2020-21-10. This AD continues to allow that termination.
    The NPRM published in the Federal Register on December 19, 2022 (87 
FR 77535). The NPRM was prompted by AD 2022-0102, dated June 8, 2022, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union (EASA AD 2022-0102) (referred to after this as the 
MCAI). The MCAI states that new or more restrictive airworthiness 
limitations have been developed to address the unsafe condition on 
these products, which, if not addressed, could result in an increased 
potential for failure of certain life-limited parts, and reduced 
structural integrity of the airplane. EASA AD 2022-0102 superseded EASA 
AD 2020-0034, dated February 25, 2020, and EASA AD 2020-0270, dated 
December 7, 2020 (which correspond to FAA AD 2020-21-10 and AD 2022-07-
08, respectively).
    EASA AD 2022-0102 specifies that the revised airworthiness 
limitations section document contains new tasks 274000-00002-1-E and 
274000-00003-1-E, which cover the inspections, corrective actions, and 
reporting previously required by EASA AD 2017-0237, dated December 4, 
2017 (which corresponds to FAA AD 2018-23-02, Amendment 39-19488 (83 FR 
59278, November 23, 2018) (AD 2018-23-02)). Accomplishing the revision 
of the existing maintenance or inspection program required by paragraph 
(n) of this AD terminates the requirements of paragraphs (g) through 
(k) of AD 2018-23-02 for Airbus SAS Model A318 series airplanes; Model 
A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model 
A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model 
A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes only.
    In the NPRM, the FAA proposed to continue to require the actions in 
AD 2020-21-10 and AD 2022-07-08. 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 2022-0102. The FAA is issuing this 
AD to address the risks associated with the effects of aging on 
airplane systems. Such effects could change system characteristics. The 
unsafe condition, if not addressed, could result in an increased 
potential for failure of certain life-limited parts, and reduced 
structural integrity of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1645.

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.

Previous Alternative Methods of Compliance (AMOCs)

    Paragraphs (r)(1)(ii) and (iii) of the proposed AD allowed previous 
AMOCs as AMOCs for the corresponding provisions of paragraph (n) of the 
proposed AD (which contain new requirements). However, the AMOC 
paragraphs did not indicate that the previous AMOCs were allowed to 
continue to be AMOCs for the retained requirements in paragraphs (g), 
(h), (j), and (k) of the proposed AD. The FAA has added paragraphs 
(r)(1)(ii) and (iii) to this AD to allow previous AMOCs as AMOCs to the 
restated requirements of this AD and reidentified subsequent paragraphs 
accordingly.

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.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2022-0102, dated June 8, 2022, which 
specifies new or more restrictive airworthiness limitations for 
airplane structures and safe life limits.
    This AD requires EASA AD 2020-0270, dated December 7, 2020, which 
the Director of the Federal Register approved for incorporation by 
reference as of May 19, 2022 (87 FR 22117, April 14, 2022).
    This AD requires EASA AD 2020-0034, dated February 25, 2020, which 
the Director of the Federal Register approved for incorporation by 
reference as of November 19, 2020 (85 FR 65190, 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 ADDRESSES.

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 2020-21-10 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA estimates the total cost per operator for the retained 
actions from AD 2022-07-08 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-

[[Page 15602]]

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.
