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.

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.
