SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Airbus SAS Model 
A319-111, A319-112, A319-113, A319-114, A319-115, A319-131, A319-132, 
A319-133, A319-151N, A319-153N, A320-211, A320-212, A320-214, A320-216, 
A320-231, A320-232, A320-233, A320-251N, A320-252N, A320-253N, A320-
271N, A320-272N, A320-273N, A321-211, A321-212, A321-213, A321-231, 
A321-232, A321-251N, A321-251NX, A321-252N, A321-252NX, A321-253N, 
A321-253NX, A321-271N, A321-271NX, A321-272N, and A321-272NX airplanes. 
The NPRM published in the Federal Register on September 25, 2024 (89 FR 
78262). The NPRM was prompted by AD 2024-0022, dated January 23, 2024, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union (EASA AD 2024-0022) (also referred to as the MCAI). 
The MCAI states that a design review led to a determination that a 
damage-tolerance and fatigue reassessment of NLG repairs is required 
for certain parts fitted on airplanes approved for CIS operation. The 
EASA AD addresses the reassessment of these repairs. The unsafe 
condition, if not addressed, could lead to damage or failure of the 
affected parts and the NLG, and possible damage to the airplane and 
injury to occupants, following modifications for CIS operations.
    Different runway standards in CIS countries have resulted in the 
need for specific landing gear modifications or repairs on those 
modified landing gears. The landing gear components modified for CIS 
runway conditions may be inadequate for continued operation. While it 
is possible there are few or no U.S. airplanes subject to the repair 
and replacement requirements of this AD, the FAA has determined that 
this AD is necessary to identify airplanes with affected parts and 
confirm the need for any follow-on actions
    In the NPRM, the FAA proposed to require repair and replacement of 
all affected parts and introduced restrictions to limit the 
installation of affected parts under certain conditions, as specified 
in EASA AD 2024-0022. The FAA is issuing this AD to address the unsafe 
condition on these products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-2314.

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.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2024-0022 specifies procedures for repair and replacement, 
as applicable, of the affected parts. EASA AD 2024-0022 also limits the 
installation of affected parts under certain conditions. 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:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                Labor cost                      Parts cost        Cost per product      Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.........                  $0                  $85   Up to $142,800.
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the repairs or replacements specified in this AD. The 
cost of parts could be as high as $5,620 per airplane.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I,

[[Page 8672]]

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.
