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

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-09-
13, which applied to certain ATR-GIE Avions de Transport 
R[eacute]gional Model ATR42-500 airplanes. AD 2021-09-13 required 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations. This 
AD was prompted by a determination that additional new or more 
restrictive airworthiness limitations are necessary. This AD retains 
the requirement of AD 2021-09-13. This AD also requires revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations, as 
specified in a European Union Aviation Safety Agency (EASA) AD, which 
is incorporated by reference. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective March 14, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 14, 
2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of June 
23, 2021 (86 FR 27031, May 19, 2021).

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2022-0396; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2021-09-13, Amendment 39-21527 (86 FR 
27031, May 19, 2021) (AD 2021-09-13) (which corresponds to EASA AD 
2020-0263, dated December 1, 2020). AD 2021-09-13 applied to certain 
ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes. 
AD 2021-09-13 required revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations. The FAA issued AD 2021-09-13 to prevent 
reduced structural integrity of the airplane.
    The NPRM published in the Federal Register on April 8, 2022 (87 FR 
20783). The NPRM was prompted by AD 2021-0212, dated September 17, 
2021, issued by EASA, which is the Technical Agent for the Member 
States of the European Union (EASA AD 2021-0212) to correct an unsafe 
condition.
    In the NPRM, the FAA proposed to retain the requirements of AD 
2021-09-13. The NPRM also proposed to require revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations, as specified in EASA AD 
2021-0212.
    The FAA issued a supplemental notice of proposed rulemaking (SNPRM) 
to amend 14 CFR part 39 to supersede AD 2021-09-13. The SNPRM published 
in the Federal Register on November 10, 2022 (87 FR 67842) (the SNPRM). 
The SNPRM was prompted by a determination that additional new or more 
restrictive airworthiness limitations are necessary; EASA superseded 
EASA AD 2021-0212 and issued EASA AD 2022-0063, dated April 8, 2022 
(EASA AD 2022-0063). EASA AD 2022-0063 was issued because ATR-GIE 
Avions de Transport published Revision 16 of the ATR 42-400/-500 Time 
Limits Document (TLD), which included new or more restrictive 
maintenance tasks and airworthiness limitations. EASA subsequently 
superseded EASA AD 2022-0063 and issued EASA AD 2022-0200, dated 
September 26, 2022 (EASA AD 2022-0200) (also referred to after this as 
the MCAI). EASA AD 2022-0200 states that since EASA AD 2022-0063 was 
issued, ATR-GIE Avions de Transport published Revision 17 of the ATR 
42-400/-500 TLD, which includes new or more restrictive maintenance 
tasks and airworthiness limitations. In the SNPRM, the FAA proposed to 
retain the requirements of AD 2021-09-13. The SNPRM also proposed to 
require revising the existing maintenance or inspection program, as 
applicable, to incorporate new and/or more restrictive airworthiness 
limitations, as specified in EASA AD 2022-0200. The FAA is issuing this 
AD to prevent reduced structural integrity of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-0396.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the SNPRM or on the determination 
of the cost to the public.

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, 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 SNPRM. None of the changes will increase the economic burden on any 
operator.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0200 describes new or more restrictive maintenance 
tasks and airworthiness limitations for

[[Page 7868]]

airplane structures and for safe life limits of the components.
    This AD also requires EASA AD 2020-0263, dated December 1, 2020, 
which the Director of the Federal Register approved for incorporation 
by reference as of June 23, 2021 (86 FR 27031, May 19, 2021).
    This service information 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 9 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2021-09-13 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate.
    The FAA estimates the total cost per operator for the new actions 
to be $7,650 (90 work-hours x $85 per work-hour).

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

    The FAA determined that 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.
