Airworthiness Directives; ATR--GIE Avions de Transport 
R[eacute]gional Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 
airplanes. This AD was prompted by a determination that some batches of 
nose landing gear (NLG) drag brace panels (DBP) having certain part 
numbers were affected by a quality deficiency that was not detected in 
production. This AD requires a measurement of the affected part and, 
depending on findings, accomplishment of applicable corrective actions, 
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 October 19, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 19, 
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 ATR--GIE Avions de 
Transport R[eacute]gional Model ATR 42-200, ATR 42-300, ATR 42-320, ATR 
42-400, ATR 42-500, ATR 72-101, ATR 72-102, ATR 72-201, ATR 72-202, ATR 
72-211, ATR 72-212, and ATR 72-212A airplanes. Model ATR 42-400 
airplanes are not certificated by the FAA and are not included on the 
U.S. type certificate data sheet; this AD therefore does not include 
those airplanes in the applicability. The NPRM published in the Federal 
Register on June 8, 2023 (88 FR 37481). The NPRM was prompted by AD 
2023-0010, dated January 17, 2023, issued by EASA, which is the 
Technical Agent for the Member States of the European Union (EASA AD 
2023-0010) (also referred to as the MCAI). The MCAI states that it has 
been determined that some batches of NLG DBP having part number (P/N) 
D63757 and P/N D69085 were affected by a quality deficiency that was 
not detected in production. Consequently, this issue could lead to NLG 
DBP dissymmetry at the lower area, which might affect the structural 
strength of the NLG DBP. This condition, if not addressed, could lead 
to NLG DBP structural fatigue failure and subsequent collapse of the 
NLG, possibly resulting in damage to the airplane and injury to 
occupants.
    In the NPRM, the FAA proposed to require a measurement of the 
affected part and, depending on findings, accomplishment of applicable 
corrective actions, as specified in EASA AD 2023-0010. 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.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1206.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from Air Line Pilots Association, 
International, 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

    EASA AD 2023-0010 specifies procedures for measuring the affected 
part and, depending on findings, accomplishing applicable corrective 
actions. Corrective actions could include obtaining and carrying out 
repair instructions, or replacing the affected part with a serviceable 
part. EASA AD 2033-0010 also specifies procedures for reporting 
measurement findings to ATR--GIE and prohibits the installation of 
affected parts.
    Safran Landing Systems SAS Service Bulletin 631-32-286, dated 
October 28, 2022, provides the list of affected parts and specifies 
measurement procedures.
    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 73 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

estimates for the on-condition actions specified in this AD.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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.
