SUPPLEMENTARY INFORMATION:

Comments Invited

The FAA invites you to send any written data, views, or arguments
about this final rule. Send your comments to an address listed under
the ADDRESSES section. Include "Docket No. FAA-2025-0622; Project
Identifier MCAI-2023-00875-R" at the beginning of your comments. The
most helpful comments reference a specific portion of the final rule,
explain the reason for any recommended change, and include supporting
data. The FAA will consider all comments received by the closing date
and may amend this final rule because of those comments.

Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
regulations.gov, including any personal information you provide. The
agency will also post a report summarizing each substantive verbal
contact received about this final rule.

Confidential Business Information

CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this AD contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this AD, it is important that you clearly designate the submitted comments as
CBI. Please mark each page of your submission containing CBI as
"PROPIN." The FAA will treat such marked submissions as confidential
under the FOIA, and they will not be placed in the public docket of
this AD. Submissions containing CBI should be sent to Adam Hein,
Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410,
Westbury, NY 11590. Any commentary that the FAA receives that is not
specifically designated as CBI will be placed in the public docket for
this rulemaking.

Background

EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2023-0140, dated July 14, 2023 (EASA
AD 2023-0140) (also referred to as the MCAI), to correct an unsafe
condition on Airbus Helicopters Model AS 332 L2 helicopters. 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 10 of AH [Airbus Helicopters]
AS 332 L2 ALS, dated March 30, 2022, has been issued to specify all
service life limits and maintenance tasks for AS 332 L2 helicopters and
separate the airworthiness limitations from the Master Servicing Manual
(M.S.M.). The FAA is issuing this AD to prevent a 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-2025-0622.

Material Incorporated by Reference Under 1 CFR Part 51

The FAA reviewed EASA AD 2023-0140, 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 2023-0140. Depending on the results of
the maintenance tasks, EASA AD 2023-0140 specifies accomplishing
corrective action(s) or contacting AH [Airbus Helicopters] for approved
instructions and accomplishing those instructions.

Additionally, EASA AD 2023-0140 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 specified in the
applicable ALS as specified in EASA AD 2023-0140 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.

FAA's Determination

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 is issuing this AD after determining
that the unsafe condition described previously is likely to exist or
develop on other products of the same type design.

AD Requirements

This AD requires the actions specified in EASA AD 2023-0140,
described previously, as incorporated by reference, except for any
differences identified as exceptions in the regulatory text of this AD.

Explanation of Required Compliance Information

In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA incorporates EASA AD 2023-0140 by reference in the FAA final rule.
This AD, therefore, requires compliance with EASA AD 2023-0140 in its
entirety through that incorporation, except for any differences
identified as exceptions in the regulatory text of this AD. Using
common terms that are the same as the heading of a particular section
in EASA AD 2023-0140 does not mean that operators need comply only with
that section. For example, where the AD requirement refers to "all
required actions and compliance times," compliance with this AD
requirement is not limited to the section titled "Required Action(s)
and Compliance Time(s)" in EASA AD 2023-0140. Material referenced in
EASA AD 2023-0140 for compliance will be available at regulations.gov
under Docket No. FAA-2025-0622 after the FAA final rule is published.

Justification for Immediate Adoption and Determination of the Effective Date

Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C.
551 et seq.) authorizes agencies to dispense with notice and comment
procedures for rules when the agency, for "good cause," finds that
those procedures are "impracticable, unnecessary, or contrary to the
public interest." Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.

There are currently no domestic operators of these products.
Accordingly, notice and opportunity for prior public comment are
unnecessary, pursuant to 5 U.S.C. 553(b). In addition, for the
foregoing reasons, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days.

Regulatory Flexibility Act

The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because the FAA has determined
that it has good cause to adopt this rule without prior notice and
comment, RFA analysis is not required.

Costs of Compliance

There are no costs of compliance with this AD because there are no
helicopters with this type certificate on the U.S. Registry.

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, and

(2) Will not affect intrastate aviation in Alaska.
