Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-14-
08, which applied to all Airbus SAS Model A319-151N, A319-153N, A319-
171N, A320-251N, A320-252N, A320-273N, A321-251N, A321-251NX, A321-
252N, A321-252NX, A321-253N, A321-253NX, A321-271N, A321-271NX, A321-
272N, and A321-272NX airplanes. AD 2021-14-08 required revising the 
existing airplane flight manual (AFM) to include a procedure to 
reinforce the airspeed check during the take-off phase and provide 
instructions to abort take-off in certain cases. This AD was prompted 
by the development of a software update to the elevator aileron 
computer (ELAC) to address the unsafe condition. This AD continues to 
require the actions in AD 2021-14-08 and requires replacing each 
affected ELAC and removing the AFM revision required by AD 2021-14-08, 
as specified in a European Union Aviation Safety Agency (EASA) AD, 
which is incorporated by reference. This AD also prohibits the 
installation of affected parts. The FAA is issuing this AD to address 
the unsafe condition on these products.

DATES: This AD is effective December 30, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 30, 
2022.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2021-14-08, Amendment 39-21635 (86 FR 
34933, July 1, 2021) (AD 2021-14-08). AD 2021-14-08 applied to all 
Airbus SAS Model A319-151N, A319-153N, A319-171N, A320-251N, A320-252N, 
A320-253N, A320-271N, A320-272N, A320-273N, A321-251N, A321-251NX, 
A321-252N, A321-252NX, A321-253N, A321-253NX, A321-271N, A321-271NX, 
A321-272N, and A321-272NX airplanes. AD 2021-14-08 required revising 
the existing AFM to include a procedure to reinforce the airspeed check 
during the take-off phase and provide instructions to abort take-off in 
certain cases. The FAA issued AD 2021-14-08 to address airspeed 
discrepancies, which could lead to an unstable flight path after take-
off, possibly resulting in reduced control of the airplane.
    The NPRM published in the Federal Register on August 23, 2022 (87 
FR 51617). The NPRM was prompted by AD 2022-0028, dated February 22, 
2022, issued by EASA, which is the Technical Agent for the Member 
States of the European Union (EASA AD 2022-0028) (referred to after 
this as the MCAI). The MCAI states that an increasing number of 
operational disruptions due to airspeed discrepancies were reported, 
which may affect the airplane's response, particularly during the 
rotation phase. The MCAI states that this condition, if not addressed, 
could lead to an unstable flight path after take-off, possibly 
resulting in reduced control of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1060.
    In the NPRM, the FAA proposed to continue to require the actions in 
AD 2021-14-08 and to require replacing each affected ELAC and removing 
the AFM revision required by AD 2021-14-08, as specified in EASA AD 
2022-0028. The NPRM also proposed to prohibit the installation of 
affected parts. The FAA is issuing this AD to address the unsafe 
condition on these products.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments 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.

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.
