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 A330-200, A330-200 Freighter, A330-300, A330-800, 
A330-900, A340-200, and A340-300 series airplanes. This AD was prompted 
by a determination that certain landing gear parts have been 
manufactured with improper material or using a deviating manufacturing 
process. This AD requires replacing each affected part with a 
serviceable part, and for certain airplanes, re-assessing any 
previously repaired main landing gear (MLG) sliding piston, as 
specified in a European Union Aviation Safety Agency (EASA) AD, which 
is incorporated by reference. This AD also limits 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 9, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 9, 
2023.

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 
A330-200, A330-200 Freighter, A330-300, A330-800, A330-900, A340-200, 
and A340-300 series airplanes. The NPRM published in the Federal 
Register on September 19, 2022 (87 FR 57153). The NPRM was prompted by 
AD 2022-0049, dated March 21, 2022, issued by EASA, which is the 
Technical Agent for the Member States of the European Union (EASA AD 
2022-0049) (also referred to as the MCAI). The MCAI states that certain 
landing gear parts have been

[[Page 6975]]

manufactured with improper material and/or using a deviating 
manufacturing processes. This condition, if not corrected, could lead 
to nose landing gear (NLG) or MLG structural fatigue failure and 
subsequent collapse of a landing gear, possibly resulting in damage to 
the airplane and injury to occupants.
    In the NPRM, the FAA proposed to require replacing each affected 
part with a serviceable part, and for certain airplanes, re-assessing 
any previously repaired MLG sliding piston, as specified in EASA AD 
2022-0049. The NPRM also proposed to limit the installation of affected 
parts under certain conditions. The FAA is issuing this AD to address 
possible NLG or MLG structural fatigue failure and subsequent collapse, 
which could result in damage to the airplane and injury to occupants.

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.
    The FAA received an additional comment from American Airlines. The 
following presents the comment received on the NPRM and the FAA's 
response.

Request To Allow Maintenance Records Review for Identification of 
Affected Parts

    American Airlines (AAL) requested that operators be allowed to use 
a maintenance records review for identifying affected parts. AAL 
asserted that a maintenance records review is usually permitted for 
identifying affected parts ``provided the part number and serial number 
of each component can be conclusively identified by that review.'' AAL 
added that it asked EASA about this issue and EASA stated that ``. . . 
any method, which is acceptable to the NAA responsible for AD 
enforcing, is acceptable'' for determining whether a part is affected. 
AAL noted that it does not believe the EASA response allows FAA 
operators to use a maintenance records review.
    The FAA agrees to clarify. This AD does not directly require 
determining whether or not a part is affected, but instead requires 
actions for airplanes that have an affected part installed and limits 
the installation of affected parts. Therefore, operators may use any 
method they choose, including a records review, for determining whether 
they have an affected part, provided the part number and serial number 
can be conclusively determined. Since the determination is not an AD 
requirement, the FAA has not changed this AD regarding this issue.

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 
comments 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

    EASA AD 2022-0049 specifies procedures for replacing each affected 
part with a serviceable part before exceeding the applicable revised 
life limit, and, for airplanes with a previously repaired MLG sliding 
piston, re-assessing the repaired part, which involves obtaining and 
following instructions from the FAA, EASA, or Airbus SAS's EASA Design 
Organization Approval (DOA). 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 the ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 128 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
----------------------------------------------------------------------------------------------------------------
Up to 49 work-hours x $85 per hour =   Up to $692,323 (per      Up to $696,489 (per      Up to $89,150,592.
 $4,165 (per MLG).                      MLG).                    MLG).
Up to 11 work-hours x $85 per hour =   Up to $260,410.........  Up to $261,346.........  Up to $33,452,288.
 $935 (NLG).
----------------------------------------------------------------------------------------------------------------
* The FAA notes that not every MLG or NLG will need to be replaced on every airplane and that operators may have
  serviceable parts in stock, thereby reducing the costs on U.S. operators. Depending on the flight hours and
  landings on the landing gear, the FAA estimates that the replacement period for all affected MLG and NLG will
  be more than two years. Additionally, the FAA has received no definitive data on which to base the cost
  estimates for the re-assessment actions 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:

[[Page 6976]]

    (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.
