2022-27405. Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

The FAA is superseding Airworthiness Directive (AD) 2018-18-05, which applied to certain ATR-GIE Avions de Transport Régional Model ATR42-200, -300, and -320 airplanes; and AD 2020-09-16, which applied to all ATR-GIE Avions de Transport Régional Model ATR42-200, -300, and -320 airplanes. AD 2018-18-05 and AD 2020-09-16 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD is prompted by a determination that additional new or more restrictive airworthiness limitations are necessary. This AD retains the requirements of AD 2020-09-16. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive maintenance requirements and 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 January 23, 2023.

The Director of the Federal Register approved the incorporation by reference of a certain publications listed in this AD as of January 23, 2023.

The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of June 22, 2020 (85 FR 29596, May 18, 2020).

SUPPLEMENTARY INFORMATION:

Background

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2018-18-05, Amendment 39-19384 (83 FR 44463, August 31, 2018) (AD 2018-18-05), which applied to certain ATR-GIE Avions de Transport Régional Model ATR42-200, -300, and -320 airplanes; and AD 2020-09-16, Amendment 39-19912 (85 FR 29596, May 18, 2020) (AD 2020-09-16), which applied to all ATR-GIE Avions de Transport Régional Model ATR42-200, -300, and -320 airplanes. AD 2018-18-05 and AD 2020-09-16 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. AD 2020-09-16 also specified that accomplishing the maintenance or inspection program revision required by paragraph (g) of that AD terminates the requirements of AD 2018-18-05. The FAA issued AD 2018-18-05 and AD 2020-09-16 to prevent reduced structural integrity of the airplane.

The NPRM published in the Federal Register on April 6, 2022 (87 FR 19818). The NPRM was prompted by AD 2021-0211, dated September 17, 2021, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2021-0211) to correct an unsafe condition.

In the NPRM, the FAA proposed to retain the requirements of AD 2020-09-16. 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 2021-0211.

The FAA issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2018-18-05 and AD 2020-09-16. The SNPRM published in the Federal Register on September 23, 2022 (87 FR 58038) (the SNPRM). The SNPRM was prompted by a determination that additional new or more restrictive airworthiness limitations are necessary; these limitations are specified in EASA AD 2022-0062, dated April 8, 2022 (EASA AD 2022-0062) (also referred to as the MCAI), which superseded EASA AD 2021-0211. In the SNPRM, the FAA proposed to retain the requirements of AD 2020-09-16. The SNPRM also proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive maintenance requirements and airworthiness limitations, as specified in EASA AD 2022-0062. 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-2022-0395.

Discussion of Final Airworthiness Directive

Comments

The FAA received a comment from the Air Line Pilots Association, International (ALPA), who supported the SNPRM 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 the AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. This AD is adopted as proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

EASA AD 2022-0062 describes new or more restrictive maintenance tasks and airworthiness limitations for airplane structures and components.

This AD also requires EASA AD 2019-0256, dated October 17, 2019, which the Director of the Federal Register approved for incorporation by reference as of June 22, 2020 (85 FR 29596, May 18, 2020).

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 26 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 2020-09-16 to be $7,650 (90 work-hours × $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 × $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 has 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.
