14 CFR Part 39

[Docket No. FAA-2023-1043; Project Identifier MCAI-2022-01295-E; 
Amendment 39-22515; AD 2023-15-03]
RIN 2120-AA64


Airworthiness Directives; Safran Helicopter Engines, S.A. Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Safran Helicopter Engines, S.A. (Safran) Model Arrius 2B2 engines. This 
AD is prompted by the manufacturer revising the airworthiness 
limitations section (ALS) of the existing engine maintenance manual 
(EMM), introducing new and more restrictive tasks and limitations for 
certain life-limited parts. This AD requires revising the ALS of the 
existing EMM or instructions for continued airworthiness (ICA) and the 
existing approved maintenance or inspection program, as applicable, by 
incorporating the actions and associated thresholds and intervals, 
including life limits, as specified in a European Union Aviation Safety 
Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective September 7, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 7, 
2023.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2023-1043; 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 by adding an AD that would apply to all Safran Model Arrius 
2B2 engines. The NPRM published in the Federal Register on May 15, 2023 
(88 FR 30911). The NPRM was prompted by EASA AD 2022-0203, dated 
September 30, 2022 (EASA AD 2022-0203), issued by EASA, which is the 
Technical Agent for the Member States of the European Union (also 
referred to as the MCAI). The MCAI states that the manufacturer 
published a revised ALS introducing new and more restrictive tasks and 
limitations for certain life-limited parts. The more restrictive tasks 
and limitations include replacing life-limited parts before exceeding 
the applicable life limit, performing applicable maintenance tasks, and 
revising the approved aircraft maintenance program.
    In the NPRM, the FAA proposed to require accomplishing the actions 
specified in the MCAI described previously. 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-2023-1043.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    These products have been approved by the aviation authority of 
another country and are 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 these products. Except for minor editorial changes, this AD is 
adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2022-0203, which specifies instructions 
for accomplishing the actions specified in the applicable ALS, 
including replacing life-limited parts, performing maintenance tasks, 
and revising the existing approved aircraft maintenance program by 
incorporating the limitations, tasks, and associated thresholds and 
intervals described in the ALS.
    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 ADDRESSES.

Differences Between This AD and the MCAI

    Paragraph (1) of EASA AD 2022-0203 requires replacing each 
component before exceeding the applicable life limit and, within the 
thresholds and intervals, accomplishing all applicable maintenance 
tasks after its effective date, this AD requires revising the ALS of 
the existing EMM or ICA and the existing approved maintenance or 
inspection program, as applicable, by incorporating the actions 
specified in paragraph (1) of EASA AD 2022-0203, within 90 days after 
the effective date of this AD. This AD does not require compliance with 
paragraphs (2) through (5) of EASA AD 2022-0203.

Costs of Compliance

    The FAA estimates that this AD affects 185 engines installed on 
helicopters of U.S. registry.

    The FAA estimates the following costs to comply with 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:
    (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.
