Abstract
The FAA is adopting a new airworthiness directive (AD) for all GE Aviation Czech s.r.o. (GEAC) M601D-11 model turboprop engines. This AD was prompted by the manufacturer revising the airworthiness limitations section (ALS) of the existing engine maintenance manual (EMM) to include a visual inspection of the centrifugal compressor case for cracks. This AD requires revising the ALS of the existing EMM to incorporate a visual inspection of the centrifugal compressor case. The FAA is issuing this AD to address the unsafe condition on these products.

-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
GE Aviation Czech s.r.o. (GEAC) M601D-11 model turboprop engines. This
AD was prompted by the manufacturer revising the airworthiness
limitations section (ALS) of the existing engine maintenance manual
(EMM) to include a visual inspection of the centrifugal compressor case
for cracks. This AD requires revising the ALS of the existing EMM to

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 GEAC M601D-11 model
turboprop engines. The NPRM published in the Federal Register on April
14, 2022 (87 FR 22149). The NPRM was prompted by the manufacturer
revising the ALS of the existing EMM to include a visual inspection of
the centrifugal compressor case for cracks. In the NPRM, the FAA
proposed to require revising the ALS of the existing EMM to incorporate
a visual inspection of the centrifugal compressor case for cracks. In
the NPRM, the FAA proposed that an owner/operator (pilot) holding at
least at least a private pilot certificate may revise the ALS of the
existing EMM, and the owner/operator must enter compliance with the
applicable paragraphs of the AD into the aircraft records in accordance
with 14 CFR 43.9(a) and 14 CFR 91.417(a)(2)(v). This is an exception to
the FAA's standard maintenance regulations. The FAA is issuing this AD
to address the unsafe condition on these products.
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union, has issued
EASA AD 2021-0060, dated March 3, 2021 (referred to after this as ``the
MCAI''), to address the unsafe condition on these products. The MCAI
states:
The airworthiness limitations for certain M601 engine models,
which are approved by EASA, are currently defined and published in
the ALS.
These instructions have been identified as mandatory for
continued airworthiness.
Failure to accomplish these instructions could result in an
unsafe condition.
Recently, GEAC published the ALS, as defined in this [EASA] AD,
introducing a visual inspection of the Centrifugal Compressor Case.
For the reason described above, this [EASA] AD requires
accomplishment of the actions specified in the ALS.
You may obtain further information by examining the MCAI in the AD
docket at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating
Docket No. FAA-2022-0459.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
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. This AD is
adopted as proposed in the NPRM.
Related Service Information
The FAA reviewed GE Aviation Czech Airworthiness Limitations R18,
Section 5. Mandatory Inspections, of the GE Aviation Czech EMM, Part
No. 0982309, Revision No. 18, dated December 18, 2020 (Airworthiness
Limitations R18, Section 5. Mandatory Inspections). Airworthiness
Limitations R18, Section 5. Mandatory Inspections, of the EMM describe
procedures for performing a visual inspection of the centrifugal
compressor case for cracks.
Costs of Compliance
The FAA estimates that this AD affects 7 engines installed on
airplanes 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 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.

Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2022-13-16 GE Aviation Czech s.r.o (Type Certificate previously held
by WALTER Engines a.s., Walter a.s., and MOTORLET a.s.): Amendment
39-22102; Docket No. FAA-2022-0459; Project Identifier MCAI-2021-
00266-E.
(a) Effective Date

Compressor Section.
(e) Unsafe Condition
This AD was prompted by the manufacturer revising the
airworthiness limitations section (ALS) of the existing engine
maintenance manual (EMM) to include a visual inspection of the
centrifugal compressor case for cracks. The FAA is issuing this AD
to prevent failure of the centrifugal compressor case. The unsafe
condition, if not addressed, could result in failure of the
centrifugal compressor case, engine separation, and loss of the
airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions

(2) After revising the ALS of the existing EMM required by
paragraph (g)(1) of this AD, no alternative inspection intervals may
be used unless they are approved as provided in paragraph (h) of
this AD.
(3) The action required by paragraph (g)(1) of this AD may be
performed by the owner/operator (pilot) holding at least a private
pilot certificate and must be entered into the aircraft records
showing compliance with this AD in accordance with 14 CFR 43.9(a)
and 14 CFR 91.417(a)(2)(v). The record must be maintained as
required by 14 CFR 91.417, 121.380, or 135.439.
(h) Alternative Methods of Compliance (AMOCs)

AMOCs for this AD, if requested using the procedures found in 14 CFR
39.19. In accordance with 14 CFR 39.19, send your request to your
principal inspector or local Flight Standards District Office, as
appropriate. If sending information directly to the manager of the
ECO Branch, send it to the attention of the person identified in
paragraph (i)(1) of this AD and email it to: <a href="/cdn-cgi/l/email-protection#c0818e85ed8184ed818d8f8380a6a1a1eea7afb6"><span class="__cf_email__" data-cfemail="e1a0afa4cca0a5cca0acaea2a1878080cf868e97">[email protected]</span></a>.
