Abstract
The FAA is adopting a new airworthiness directive (AD) for all GE Aviation Czech s.r.o. (GEAC) (type certificate previously held by WALTER Engines a.s., Walter a.s., and MOTORLET a.s.) Model M601E-11AS, M601E-11S, H75-100, H80-100, and H85-100 engines. This AD is prompted by reports of multiple failures of the needle bearing installed in propeller governors having part numbers (P/Ns) P-W11-1 or P-W11-2, caused by self-generated debris from the needle bearing, which led to oil contamination. This AD requires replacement of the affected propeller governors with a redesigned propeller governor and prohibits installation of the affected propeller governors, 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.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
GE Aviation Czech s.r.o. (GEAC) (type certificate previously held by
WALTER Engines a.s., Walter a.s., and MOTORLET a.s.) Model M601E-11AS,
M601E-11S, H75-100, H80-100, and H85-100 engines. This AD is prompted
by reports of multiple failures of the needle bearing installed in
propeller governors having part numbers (P/Ns) P-W11-1 or P-W11-2,
caused by self-generated debris from the needle bearing, which led to
oil contamination. This AD requires replacement of the affected
propeller governors with a redesigned propeller governor and prohibits
installation of the affected propeller governors, 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.

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 Model M601E-
11AS, M601E-11S, H75-100, H80-100, and H85-100 engines. The NPRM
published in the Federal Register on April 7, 2023 (88 FR 20784). The
NPRM was prompted by EASA AD 2022-0234, dated December 1, 2022, issued
by EASA, which is the Technical Agent for the Member States of the
European Union (referred to after this as the MCAI). The MCAI states
that there have been reports of multiple needle bearing failures that
affect propeller governors having P/Ns P-W11-1 and P-W11-2. Further
investigation revealed that those failures were caused by self-
generated debris from the needle bearing, which led to oil
contamination.
In the NPRM, the FAA proposed to require accomplishing the actions
specified in EASA AD 2022-0234, described previously, except for any
differences or exceptions identified in the NPRM. The FAA is issuing
this AD to address the unsafe condition on these products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-0664.
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 2022-0234, which specifies procedures for
the replacement of propeller governors having P/Ns P-W11-1 and P-W11-2
with a redesigned propeller governor.
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.
Costs of Compliance
The FAA estimates that this AD affects seven engines installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:
[[Page 44034]]
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Remove and replace propeller 3 work-hours x $85 per $7,000 $7,255 $50,785
governor. hour = $255.
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected operators.
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.
