Airworthiness Directives; GE Aviation
Czech s.r.o. (Type Certificate
Previously Held by WALTER Engines
a.s., Walter a.s., and MOTORLET a.s.)
Turboprop Engines
Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for all
GE Aviation Czech s.r.o. (GEAC)
M601E–11AS, M601E-11S, H75–100,
H80–100, and H85–100 model
turboprop engines. This proposed AD
was 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 proposed AD
would require replacement of the
affected propeller governors with a
redesigned propeller governor, and
would prohibit installation of the
affected propeller governors, as
specified in a European Union Aviation
Safety Agency (EASA) AD, which is
proposed for incorporation by reference
(IBR). The FAA is proposing this AD to
address the unsafe condition on these
products.
SUMMARY:
The FAA must receive comments
on this proposed AD by May 22, 2023.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Background
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2022–0234,
dated December 1, 2022 (EASA AD
2022–0234) (also referred to as the
MCAI), to address an unsafe condition
for all GEAC M601E–11AS, M601E–11S,
M601FS, H75–100, H80–100 and H85–
100 model turboprop engines. Model
M601FS turboprop engines do not have
an FAA type certificate, therefore this
proposed AD does not include those
engines in the applicability. 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 response to the
unsafe condition, the manufacturer
developed a redesigned propeller
governor to replace propeller governors
having P/Ns P–W11–1 and P–W11–2.
You may examine the MCAI in the
AD docket at regulations.gov under
Docket No. FAA–2023–0664.
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.
FAA’s Determination
These products have been approved
by the aviation authority of another
PO 00000
Frm 00006
Fmt 4702
Sfmt 4702
20785
country and are approved for operation
in the United States. Pursuant to the
FAA’s bilateral agreement with the State
of Design Authority, it has notified the
FAA of the unsafe condition described
in the MCAI described above. The FAA
is issuing this NPRM after determining
that the unsafe condition described
previously is likely to exist or develop
in other products of these same type
designs.
Proposed AD Requirements in This
NPRM
This proposed AD would require
accomplishing the actions specified in
EASA AD 2022–0234, described
previously, except for any differences
identified as exceptions in the
regulatory text of this proposed 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 since coordinated
with other manufacturers and CAAs to
use this process. As a result, the FAA
proposes to incorporate by reference
EASA AD 2022–0234 in the FAA final
rule. This proposed AD would,
therefore, require compliance with
EASA AD 2022–0234 in its entirety
through that incorporation, except for
any differences identified as exceptions
in the regulatory text of this proposed
AD. Using common terms that are the
same as the heading of a particular
section in the EASA AD 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 2022–0234.
Service information required by the
EASA AD for compliance will be
available at regulations.gov by searching
for and locating Docket No. FAA–2023–
0664 after the FAA final rule is
published.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect seven
engines installed on airplanes of U.S.
registry.
The FAA estimates the following
costs to comply with this proposed AD:
E:\FR\FM\07APP1.SGM

Remove and replace propeller governor ........
3 work-hours × $85 per hour = $255 .............
$7,000

The FAA has included all known
costs in its cost estimate. According to
the manufacturer, however, some or all
of the costs of this proposed 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.
ddrumheller on DSK120RN23PROD with PROPOSALS1
Regulatory Findings
The FAA determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 proposed regulation:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Would not affect intrastate
aviation in Alaska, and
(3) Would not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
PART 39—AIRWORTHINESS

(d) Subject
Joint Aircraft Service Component (JASC)
Code 6122, Propeller governor; 7200, Engine
(turbine/turboprop).
(e) Unsafe Condition
This AD was prompted by multiple failures
of the needle bearing installed in certain
propeller governors, caused by self-generated
debris from the needle bearing, which led to
oil contamination. The FAA is issuing this
AD to prevent needle bearing failures in
certain propeller governors. The unsafe
condition, if not addressed, could result in
loss of propeller control oil pressure, failure
of the engine, reduced control of the airplane,
and damage to the airplane.

I. Background
The PSRA, enacted on April 6, 2022,
amended Title 39 of the United States
Code and other relevant statutory
provisions. Among other changes,
section 203 of the PSRA added a note
to 39 U.S.C. 3633, which requires that
the Commission, no later than April 6,
2023, ‘‘initiate a review of the
regulations issued pursuant to sections
3633(a) and 3652(a)(1) of title 39, United
States Code, to determine whether
revisions are appropriate to ensure that
VerDate Sep<11>2014
17:18 Apr 06, 2023
Jkt 259001
all direct and indirect costs attributable
to competitive and market-dominant
products are properly attributed to those
products, including by considering the
underlying methodologies in
determining cost attribution and
considering options to revise such
methodologies.’’ PSRA section 203.
Section 203 also specifies that, if, after
notice and public comment, the
Commission determines ‘‘that revisions
are appropriate, the Commission shall
make modifications or adopt alternative
methodologies as necessary.’’ See id.
The Postal Service uses a two-tier
costing system to categorize its accrued
costs. The Postal Service first identifies
all costs that can be reliably and
causally linked to individual postal
products or groups of products, using
Commission-approved analytical
principles, and attributes those costs to
products or product groupings. All
remaining costs are classified as
institutional. This two-tier postal
costing approach, which is deeply
rooted in the Postal Service’s historical
treatment of costs,1 has been adopted
into Title 39 of the United States Code.2
Specifically, Sections 3631(b) and
3622(c) of Title 39 of the United States
Code expressly codify ‘‘reliably
identified causal relationships’’ as the
standard for cost attribution. A detailed
description of the approach to postal
cost attribution currently employed by
the Postal Service and the Commission
appears in Docket Nos. RM2017–1 and
RM2022–2.3
Since the enactment of the Postal
Accountability and Enhancement Act
(PAEA) and the Commission’s
subsequent promulgation of
regulations,4 the Postal Service has

implementing the Postal Reorganization Act,
Public Law 91–375, 84 Stat. 719 (1970), the former

approach to costing. That approach was upheld by
the Supreme Court of the United States. See Nat’l
Ass’n of Greeting Card Publishers v. U.S. Postal
Serv., 462 U.S. 810, 833 (1983) (specifically
rejecting the imposition of an intermediary tier of
costs, based on extended inferences of causation,

improved the information used as the
basis for cost attribution by changing or
upgrading numerous data systems and
updating and improving special cost
studies. As a result, the Commission has
presided over numerous rulemakings
that have affected cost attribution.
Cost attribution can be affected in
major or minor ways through
Commission proceedings that involve
changes in ‘‘analytical principles.’’
Analytical principles refer to economic,
mathematical, or statistical theories,
precepts, or assumptions applied by the
Postal Service in producing required
periodic reports. See 39 CFR 3050.1(c).
Analytical principles include, but are
not limited to, costing methodologies
and cost models that the Postal Service
relies upon to generate cost-related data.
The Commission has presided over
many such proceedings to change
accepted analytical principles since the
PAEA was enacted.
II. Invitation To Comment
The Commission invites interested
persons to comment on regulations
related to Postal Service cost attribution,
as well as the analytical principles
(including costing methodologies or cost
models) underlying postal cost
attribution. Comments should focus on
whether revisions to any regulations or
analytical principles are necessary ‘‘to
ensure that all direct and indirect costs
attributable to competitive and marketdominant products are properly
attributed to those products . . . .’’
PSRA section 203. Commenters are
reminded that the scope of this docket
is focused on regulations and analytical
principles pertaining to cost attribution.
III. Administrative Actions
Pursuant to section 203 of the PSRA,
the Commission establishes Docket No.
PI2023–2 in order to review regulations
issued pursuant to 39 U.S.C. 3633(a)
and 3652(a)(1) relevant to the issue of
postal cost attribution, as well as
analytical principles (including costing
methodologies or cost models) relevant
to postal cost attribution. The
Commission intends to evaluate the
comments received and use those
suggestions to help carry out the
responsibilities described in section 203
of the PSRA. Comments are due no later
than June 14, 2023. Reply comments are
due no later than July 14, 2023.
Comments and other material filed in
this proceeding will be available for
review on the Commission’s website

RIN 2120-AA64
Airworthiness Directives; GE Aviation Czech s.r.o. (Type
Certificate Previously Held by WALTER Engines a.s., Walter a.s., and
MOTORLET a.s.) Turboprop Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for all GE Aviation Czech s.r.o. (GEAC) M601E-11AS, M601E[hyphen]11S,
H75-100, H80-100, and H85-100 model turboprop engines. This proposed AD
was 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 proposed AD would require replacement of
the affected propeller governors with a redesigned propeller governor,
and would prohibit installation of the affected propeller governors, as
specified in a European Union Aviation Safety Agency (EASA) AD, which
is proposed for incorporation by reference (IBR). The FAA is proposing
this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by May 22,
2023.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:
Comments Invited
The FAA invites you to send any written relevant data, views, or
arguments about this proposal. Send your comments to an address listed
under ADDRESSES. Include ``Docket No. FAA-2023-0664; Project Identifier
MCAI-2022-01527-E'' at the beginning of your comments. The most helpful
comments reference a specific portion of the proposal, 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 proposal 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 NPRM.
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 NPRM 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 NPRM, 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 NPRM. Submissions containing CBI should be sent to
Barbara Caufield, Aviation Safety Engineer, ECO Branch, FAA, 1200
District Avenue, Burlington, MA 01803. Any commentary that the FAA
receives which 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 2022-0234, dated December 1, 2022
(EASA AD 2022-0234) (also referred to as the MCAI), to address an
unsafe condition for all GEAC M601E-11AS, M601E-11S, M601FS, H75-100,
H80-100 and H85-100 model turboprop engines. Model M601FS turboprop
engines do not have an FAA type certificate, therefore this proposed AD
does not include those engines in the applicability. 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 response to the unsafe condition, the manufacturer
developed a redesigned propeller governor to replace propeller
governors having P/Ns P-W11-1 and P-W11-2.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2023-0664.
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.
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 the State of Design
Authority, it has notified the FAA of the unsafe condition described in
the MCAI described above. The FAA is issuing this NPRM after
determining that the unsafe condition described previously is likely to
exist or develop in other products of these same type designs.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in EASA AD 2022-0234, described previously, except for any differences
identified as exceptions in the regulatory text of this proposed 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 since
coordinated with other manufacturers and CAAs to use this process. As a
result, the FAA proposes to incorporate by reference EASA AD 2022-0234
in the FAA final rule. This proposed AD would, therefore, require
compliance with EASA AD 2022-0234 in its entirety through that
incorporation, except for any differences identified as exceptions in
the regulatory text of this proposed AD. Using common terms that are
the same as the heading of a particular section in the EASA AD 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 2022-0234. Service information required by the EASA AD for
compliance will be available at regulations.gov by searching for and
locating Docket No. FAA-2023-0664 after the FAA final rule is
published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect seven engines installed on airplanes of U.S. registry.
The FAA estimates the following costs to comply with this proposed
AD:
[[Page 20786]]
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 or all of the costs of
this proposed 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
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
