Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
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. This AD was prompted by a 
report of a nose landing gear (NLG) sliding tube rupture that led to a 
NLG collapse. This AD requires inspection of certain NLG and main 
landing gear (MLG) sliding tubes and applicable corrective actions and 
eventual replacement of all affected parts, as specified in a European 
Union Aviation Safety Agency (EASA) AD, which is incorporated by 
reference (IBR). This AD also prohibits the installation of affected 
parts under certain conditions. The FAA is issuing this AD to address 
the unsafe condition on these products.

DATES: This AD is effective March 8, 2023.
    The Director of the Federal Register approved the incorporation by 
reference

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 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. The NPRM published in the Federal Register on October 
20, 2022 (87 FR 63715). The NPRM was prompted by AD 2021-0236, dated 
October 29, 2021, issued by EASA, which is the Technical Agent for the 
Member States of the European Union (EASA AD 2021-0236) (also referred 
to as the MCAI). The MCAI states that NLG sliding tube rupture, leading 
to NLG collapse during taxiing, occurred on a Model A320 airplane. 
Investigations identified overheat damage on that NLG, caused by 
incorrect accomplishment of a repair on the chromium-plated diameter of 
the sliding tube during the last NLG overhaul. Further investigations 
identified a batch of NLG and MLG sliding tubes that are possibly 
affected by a similar condition, which, if not detected and corrected, 
could lead to NLG or MLG structural failure and subsequent collapse of 
the gears, possibly resulting in damage to the airplane and injury to 
occupants.
    In the NPRM, the FAA proposed to require inspection of certain NLG 
and MLG sliding tubes and applicable corrective actions and eventual 
replacement of all affected parts. The NPRM also proposed to prohibit 
the installation of affected parts under certain conditions. The FAA is 
issuing this AD to address NLGs and MLGs that may have been subject to 
the incorrect accomplishment of a repair, which, if not detected and 
corrected, could lead to NLG or MLG structural failure and subsequent 
collapse of the gears, possibly resulting in damage to the airplane and 
injury to occupants.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1295.

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 2021-0236, which specifies procedures for 
a detailed inspection of the visible chrome surface of affected NLG and 
MLG sliding tubes for any discrepancies (cracks), a magnetic particle 
inspection (MPI) and Barkhausen noise inspection (BNI) of affected 
parts for any discrepancies (cracks), eventual replacement of affected 
parts, and corrective actions. Corrective actions include immediate 
replacement of the NLG or MLG sliding tube or shock absorber. 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 1,825 airplanes of U.S. 
registry. Currently, there are no affected U.S.-registered airplanes 
that would need the required actions because the affected part is not 
installed on any U.S.-registered airplanes. U.S.-registered airplanes 
therefore would need to comply with only the parts prohibition 
specified in this AD.
    If an affected airplane is imported and placed on the U.S. Register 
in the future, the FAA provides the following cost estimates to comply 
with the required actions in this AD:

                  Estimated Costs for Required Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                  Parts cost *       product
------------------------------------------------------------------------
50 work-hours x $85 per hour = $4,250.              $0           $4,250
------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost
  estimates for the replacement parts specified in this AD.

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.
