Background
Transport Canada, which is the
aviation authority for Canada, has
issued Transport Canada AD CF–2022–
26, dated May 26, 2022 (Transport
Canada AD CF–2022–26) (referred to
after this as ‘‘the MCAI’’), to address an
unsafe condition for P&WC PT6E–67XP
model turboprop engines with serial
number HP0194 and earlier. The MCAI
states that there have been reports of
multiple incidents in which engines
were unable to achieve the required
power (torque) during high power
applications. A manufacturer
E:\FR\FM\18NOP1.SGM
18NOP1
Federal Register / Vol. 87, No. 222 / Friday, November 18, 2022 / Proposed Rules
investigation found that contamination
from the glass beads used in the
manufacturing process during the gas
generator casing (GGC) production
caused internal leaks in the BOVs,
preventing the BOVs from fully closing
at high power settings. The FAA is
issuing this AD to prevent internal leaks
in the BOVs, and to prevent the failure
of the engine to achieve the required
power (torque) during high power
applications.
You may examine the MCAI in the
AD docket at regulations.gov under
Docket No. FAA–2022–1477.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Transport Canada
AD CF–2022–26, which specifies
procedures for the replacement of the
compressor BOV assembly, replacement
of the BOV orifice feed air tube
assembly, and installation of a
redesigned P3 probe snorkel.
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 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 this
State of Design Authority, it has notified
the FAA of the unsafe condition
69219
This proposed AD would require
accomplishing the actions specified in
Transport Canada AD CF–2022–26,
described previously, except for any
differences identified as exceptions in
the regulatory text of this proposed AD
and except as discussed under
‘‘Differences Between This Proposed AD
and the MCAI.
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 Transport Canada AD does not mean
that operators need comply only with
that section. For example, where the AD
requirement refers to ‘‘Compliance,’’
compliance with this AD requirement is
not limited to the section titled
‘‘Corrective Actions’’ in Transport
Canada AD CF–2022–26. Service
information required by the Transport
Canada AD for compliance will be
available at regulations.gov by searching
for and locating Docket No. FAA–2022–
1477 after the FAA final rule is
published.
Explanation of Required Compliance
Information
Differences Between This Proposed AD
and the Transport Canada AD
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
Transport Canada AD CF–2022–26 in
the FAA final rule. This proposed AD
would, therefore, require compliance
with Transport Canada AD CF–2022–26
in its entirety through that
incorporation, except for any differences
Where Transport Canada AD CF–
2022–26 refers to hours air time, this
proposed AD requires using flight
hours.
Where Transport Canada AD CF–
2022–26 specifies compliance from its
effective date, this proposed AD would
require using the effective date of this
proposed AD.
described in the Transport Canada AD
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
the same type design
Proposed AD Requirements in This
NPRM
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 100
engines installed on airplanes of U.S.
registry.
The FAA estimates the following
costs to comply with this proposed AD:
ESTIMATED COSTS
Action
Labor cost
Replace compressor BOV assembly ..............
Replace BOV orifice feed air tube assembly
with P3 probe snorkel and BOV orifice feed
air tube assembly.
5 work-hours × $85 per hour = $425 .............

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

Jkt 259001
Parts cost
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.

AGENCY:
SUMMARY: The FAA proposes to
supersede Airworthiness Directive (AD)
2022–01–09, which applies to certain
Stemme AG Model Stemme S 10–VT
and Model Stemme S 12 gliders. AD
2022–01–09 requires removing the
affected freewheel clutch from service
and prohibits the installation of affected
parts. Since the FAA issued AD 2022–
01–09, the European Union Aviation
Safety Agency (EASA) superseded its
mandatory continuing airworthiness
information (MCAI) to amend the
definition of an affected part. This
proposed AD would retain the
requirements of AD 2022–01–09 for
removing the affected freewheel clutch
from service and continue to prohibit
the installation of an affected part, and
would amend the definition of an
affected part and clarify the part
installation prohibition. The FAA is
proposing this AD to address the unsafe
condition on these products.

Related Service Information Under 1 CFR Part 51
The FAA reviewed Transport Canada AD CF-2022-26, which specifies
procedures for the replacement of the compressor BOV assembly,
replacement of the BOV orifice feed air tube assembly, and installation
of a redesigned P3 probe snorkel.
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 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 this State of Design
Authority, it has notified the FAA of the unsafe condition described in
the Transport Canada AD 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 the same type design
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in Transport Canada AD CF-2022-26, described previously, except for any
differences identified as exceptions in the regulatory text of this
proposed AD and except as discussed under ``Differences Between This
Proposed AD and the MCAI.
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 Transport Canada
AD CF-2022-26 in the FAA final rule. This proposed AD would, therefore,
require compliance with Transport Canada AD CF-2022-26 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
Transport Canada AD does not mean that operators need comply only with
that section. For example, where the AD requirement refers to
``Compliance,'' compliance with this AD requirement is not limited to
the section titled ``Corrective Actions'' in Transport Canada AD CF-
2022-26. Service information required by the Transport Canada AD for
compliance will be available at regulations.gov by searching for and
locating Docket No. FAA-2022-1477 after the FAA final rule is
published.
Differences Between This Proposed AD and the Transport Canada AD
Where Transport Canada AD CF-2022-26 refers to hours air time, this
proposed AD requires using flight hours.
Where Transport Canada AD CF-2022-26 specifies compliance from its
effective date, this proposed AD would require using the effective date
of this proposed AD.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 100 engines installed on airplanes of U.S. registry.
The FAA estimates the following costs to comply with this proposed
AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Replace compressor BOV assembly....... 5 work-hours x $85 per $13,102 $13,527 $1,352,700

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.

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 DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
Pratt & Whitney Canada Corp.: Docket No. FAA-2022-1477; Project
Identifier MCAI-2022-00632-E.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by January 3, 2023.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Pratt & Whitney Canada Corp. (P&WC) PT6E-67XP
