14 CFR Part 39

[Docket No. FAA-2025-0467; Project Identifier MCAI-2023-00873-R; 
Amendment 39-23065; AD 2025-12-07]

Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus Helicopters Model AS332C helicopters. This AD was prompted by a 
determination that new and more restrictive airworthiness limitations 
are necessary. This AD requires revising the airworthiness limitations 
section (ALS) of the existing maintenance manual (MM) or instructions 
for continued airworthiness (ICAs) and the existing approved 
maintenance or inspection program, as applicable. The FAA is issuing 
this AD to address the unsafe condition on these products.

DATES: This AD is effective August 11, 2025.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 11, 
2025.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2025-0467; 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 Airbus Helicopters 
Model AS332C helicopters. The NPRM was published in the Federal 
Register on March 21, 2025 (90 FR 13314). The NPRM was prompted by AD 
2023-0145, dated July 14, 2023 (EASA AD 2023-0145) (also referred to as 
``the MCAI''), issued by EASA, which is the Technical Agent for the 
Member States of the European Union. The MCAI states that new or more 
restrictive airworthiness limitations have been developed. EASA advises 
that airworthiness limitations and certification maintenance 
instructions are identified as mandatory for continued airworthiness 
and that Revision 9 of Airbus Helicopters Model AS332C ALS, dated July 
27, 2022, has been issued to specify all service life limits and 
maintenance tasks for Model AS332C helicopters and separate the 
airworthiness limitations from the Master Servicing Manual.
    In the NPRM, the FAA proposed to require revising the ALS of the 
existing MM or ICAs and the existing approved maintenance or inspection 
program, as applicable. The FAA is issuing this AD to prevent failure 
of critical parts and primary structural components, which if not 
addressed could result in loss of control of the helicopter.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2025-0467.

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 civil 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, that authority has notified the FAA of the unsafe condition 
described in the MCAI referenced above. The FAA reviewed the relevant 
data, considered any comments 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 these products. 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 2023-0145, which specifies replacing 
components before exceeding their life limits and accomplishing all 
applicable maintenance tasks within thresholds and intervals specified 
in the ALS as defined in EASA AD 2023-0145. Depending on the results of 
the maintenance tasks, EASA AD 2023-0145 specifies accomplishing 
corrective action(s) or contacting Airbus Helicopters for approved 
instructions and accomplishing those instructions.
    Additionally, EASA AD 2023-0145 specifies revising the Aircraft 
Maintenance Programme (AMP) by incorporating the limitations, tasks, 
and associated thresholds and intervals described in the specified ALS, 
as applicable. Revising the AMP constitutes terminating action for the 
requirement to record accomplishment of the actions of replacing 
components before exceeding their life limits and accomplishing 
maintenance tasks within thresholds and intervals

[[Page 29718]]

specified in the applicable ALS as required by EASA AD 2023-0145 for 
demonstration of AD compliance on a continued basis.
    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 105 helicopters of U.S. 
registry. Labor rates are estimated at $85 per hour. Based on these 
numbers, the FAA estimates the following costs to comply with this AD.
    Revising the ALS of the existing MM or ICAs and the existing 
approved maintenance or inspection program, as applicable, takes 1 
work-hour, for an estimated cost of $85 per helicopter and $8,925 for 
the U.S. fleet.

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.
