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 Makila 1A,
Makila 1A1, and Makila 1A2 engines.
The NPRM published in the Federal
Register on June 20, 2024 (89 FR 51858).
The NPRM was prompted by EASA AD
2023–0218, dated December 19, 2023
(EASA AD 2023–0218) (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 it has been determined
that the accumulated service life of
certain critical parts was
underestimated. To address this
potential unsafe condition, the
manufacturer published service
information that identifies the affected
parts and provides instructions for
recalculating the service life and
replacing the affected parts. The MCAI
specifies determining the recalculated
service life of the affected parts and
replacing if necessary. The MCAI also
specifies conditions for installing the
PO 00000
Frm 00018
Fmt 4700
Sfmt 4700
affected parts. This unsafe condition, if
not addressed, could lead to operation
of the affected parts beyond the part life,
which could cause the failure of affected
parts, possibly resulting in uncontained
debris release with consequent damage
to the helicopter and reduced control of
the helicopter.
In the NPRM, the FAA proposed to
require determining the recalculated
service life of certain critical parts,
replacing the parts if necessary, and
specified conditions for installing the
parts. 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–2024–1691.
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.
Material Incorporated by Reference
Under 1 CFR Part 51
The FAA reviewed EASA AD 2023–
0218, which specifies determining the
recalculated service life of affected parts
and replacing the affected parts, if
necessary. EASA AD 2023–0218 also
specifies conditions for installing the
affected parts. 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 0 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.

2023–04–06 and AD 2024–04–07
required revising the existing
maintenance or inspection program, as
applicable, to incorporate additional
new or more restrictive airworthiness
limitations. The FAA issued AD 2023–
04–06 and AD 2024–04–07 to address a
safety-significant latent failure.
The NPRM published in the Federal
Register on June 18, 2024 (89 FR 51471).
The NPRM was prompted by AD 2024–
0030, dated January 31, 2024, issued by
EASA, which is the Technical Agent for
the Member States of the European
Union (EASA AD 2024–0030) (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
require revising the existing
maintenance or inspection program, as
applicable, to incorporate additional
new or more restrictive airworthiness
limitations, as specified in EASA AD
2024–0030. The FAA is issuing this AD
to address a safety significant latent
failure (that is not annunciated), which,
in combination with one or more other
specific failures or events, could result
in a hazardous or catastrophic failure
condition.
You may examine the MCAI in the
AD docket at regulations.gov under
Docket No. FAA–2024–1685.
Discussion of Final Airworthiness
Directive
Comments
The FAA received comments from the
Air Line Pilots Association,
International (ALPA) who supported the
NPRM without change.
Additional Changes Made To This AD
The proposed AD did not retain the
terminating action specified in
paragraph (j) of AD 2024–04–07. The
FAA has added that terminating action
to paragraph (j) of this AD and
redesignated subsequent paragraphs of
this AD accordingly.

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 Makila
1A, Makila 1A1, and Makila 1A2 engines. The NPRM published in the
Federal Register on June 20, 2024 (89 FR 51858). The NPRM was prompted
by EASA AD 2023-0218, dated December 19, 2023 (EASA AD 2023-0218) (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 it
has been determined that the accumulated service life of certain
critical parts was underestimated. To address this potential unsafe
condition, the manufacturer published service information that
identifies the affected parts and provides instructions for
recalculating the service life and replacing the affected parts. The
MCAI specifies determining the recalculated service life of the
affected parts and replacing if necessary. The MCAI also specifies
conditions for installing the affected parts. This unsafe condition, if
not addressed, could lead to operation of the affected parts beyond the
part life, which could cause the failure of affected parts, possibly
resulting in uncontained debris release with consequent damage to the
helicopter and reduced control of the helicopter.
In the NPRM, the FAA proposed to require determining the
recalculated service life of certain critical parts, replacing the
parts if necessary, and specified conditions for installing the parts.
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-2024-1691.
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.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed EASA AD 2023-0218, which specifies determining the
recalculated service life of affected parts and replacing the affected
parts, if necessary. EASA AD 2023-0218 also specifies conditions for
installing the affected parts. 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 0 engines installed on
helicopters of 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,
(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.
