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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-02-
08, which applied to certain ATR-GIE Avions de Transport 
R[eacute]gional Model ATR42-500 airplanes. AD 2023-02-08 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 new or more restrictive 
airworthiness limitations are necessary. This AD continues to require 
certain actions in AD 2023-02-08, and 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 November 15, 2024.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 15, 
2024.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of March 
14, 2023 (88 FR 7867, February 7, 2023).

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2024-1482; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains this final rule, the mandatory continuing airworthiness 
information (MCAI), any comments received, and other information. The

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2023-02-08, Amendment 39-22315 (88 FR 7867, 
February 7, 2023) (AD 2023-02-08). AD 2023-02-08 applied to certain 
ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes. 
AD 2023-02-08 required revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations. The FAA issued AD 2023-02-08 to prevent 
reduced structural integrity of the airplane.
    The NPRM published in the Federal Register on June 13, 2024 (89 FR 
50241). The NPRM was prompted by AD 2024-0052, dated February 23, 2024, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union (EASA AD 2024-0052) (also referred to as the MCAI). 
The MCAI states that new or more restrictive airworthiness limitations 
have been developed.
    In the NPRM, the FAA proposed to retain the requirements of AD 
2023-02-08. 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 
2024-0052. The FAA is issuing this AD to address among other things, 
fatigue cracking and damage in principal structural elements. The 
unsafe condition, if not addressed, could result in reduced structural 
integrity of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-1482.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from 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

    The FAA reviewed EASA AD 2024-0052 that revises the ATR42-400/-500 
Time Limits Document and incorporates EASA AD 2020-0249R1, which 
required a repetitive operational test for discrepancies of the stall 
warning system and stick pusher in the flight configuration for ATR-GIE 
Avions de Transport R[eacute]gional Model ATR42-500 and ATR72 
airplanes. This service information specifies new or more restrictive 
airworthiness limitations for airplane structures and safe life limits. 
EASA AD 2020-0249R1 revises EASA AD 2020-0249, which corresponds to FAA 
AD 2020-26-17, Amendment 39-21372 (85 FR 81795, December 17, 2020) (AD 
2020-26-17).
    This AD also requires EASA AD 2022-0200, dated September 26, 2022, 
which the Director of the Federal Register approved for incorporation 
by reference as of March 14, 2023 (88 FR 7867, February 7, 2023).
    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 17 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 2023-02-08 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

    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.

AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or responsible Flight Standards Office, as

appropriate principal inspector, or lacking a principal inspector, 
the manager of the responsible Flight Standards Office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, International 
Validation Branch, FAA; or EASA; or ATR-GIE Avions de Transport 
R[eacute]gional's EASA Design Organization Approval (DOA). If
