(d) Subject
Air Transport Association (ATA) of
America Code 25, Equipment/furnishings.
(e) Unsafe Condition
This AD was prompted by reports of
uncommanded escape slide deployments in
the passenger compartment, caused by too
much tension in the inflation cable and the
movement of the escape slide assembly in the
escape slide compartment. The FAA is
issuing this AD to address inflation of the
escape slide while it is in the escape slide
compartment, which could result in injury to
passengers and crew during normal
operation, or impede an emergency
evacuation by rendering the exit unusable.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.

visually inspecting the swashplate
assembly at specified intervals and
depending on the results, removing the
swashplate assembly from service. Since
the FAA issued AD 2022–02–01, the
FAA determined it was necessary to
expand the applicability and require
more detailed inspections to address the
unsafe condition. This AD retains the
actions of AD 2022–02–01, expands the
applicability, adds a detailed recurring
visual inspection, and requires either
eddy current inspections (ECI) or

SUPPLEMENTARY INFORMATION:
lotter on DSK11XQN23PROD with RULES1
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2022–02–01,
Amendment 39–21898 (87 FR 2316,
January 14, 2022), (AD 2022–02–01). AD
2022–02–01 applied to Sikorsky Aircraft
Corporation Model S–92A helicopters
with a swashplate assembly part

number (P/N) 92104–15011–042 or P/N
92104–15011–043 that had accumulated
1,600 or more total hours TIS, installed.
The NPRM published in the Federal
Register on January 17, 2023 (88 FR
2558). The NPRM was prompted by a
notification of an in-service crack in a
swashplate assembly inner ring. The
crack, discovered during a routine
inspection, extended between the
uniball bore and near the right-hand
trunnion to servo attach bolt hole. In the
NPRM, the FAA proposed to continue to
require, for swashplate assemblies that
have accumulated 1,600 or more total
hours TIS, a certain recurring visual
inspection and replacing the swashplate
assembly if cracks are found. In the
NPRM, the FAA proposed to require
accomplishing an FPI or ECI depending
on accrued flight time or suspicion of
cracks. In the NPRM, the FAA also
proposed to expand the visual
inspections required by AD 2022–02–01
and revise the applicability statement of
AD 2022–02–01.
Discussion of Final Airworthiness
Directive
Comments
The FAA received a comment from
one commenter, Sikorsky Aircraft
Corporation. The following presents the
comment received on the NPRM and the
FAA’s response to the comment.
Request To Clarify Previous Actions for
Compliance
Sikorsky Aircraft Corporation
requested the FAA change paragraph (f)
of the AD to state, ‘‘Comply with this
AD within the compliance times
specified, unless already accomplished
by Alert Service Bulletin. Repetitive
inspections incorporated into Sikorsky
S–92 [Aircraft Maintenance Manual]
(AMM), Chapter 5, demonstrate
compliance with the repetitive
inspections of this Airworthiness
Directive.’’ Sikorsky Aircraft
Corporation stated that it has issued two
alert service bulletins (ASBs) that
introduce both a one-time inspection
and recurrent inspections for the
existing part-numbered stationary
swashplate assemblies. In addition,
Sikorsky Aircraft Corporation stated that
the recurrent inspections have been
incorporated into the Sikorsky S–92
AMM, Chapter 5 inspection
requirements; and that the introduction
of this rule makes these inspections
mandatory and the original equipment
manufacturer (OEM) agrees. However,
Sikorsky Aircraft Corporation stated that
from the operator perspective, there may
be some confusion as to compliance
with the AD. Since the ASBs and
PO 00000
Frm 00023
Fmt 4700
Sfmt 4700
33821
Chapter 5 are in place, Sikorsky Aircraft
Corporation stated that it may be helpful
to add language in the text of the AD
explaining that the AD is not
introducing a new action if the operator
is already following the OEM
instructions, which may prevent
operators from unnecessarily repeating
inspections with which the operator
already complied. Lastly, Sikorsky
Aircraft Corporation stated that
operators who incorporate repetitive
inspections into their maintenance
programs, in this case the OEM Chapter
5, are demonstrating compliance with
the repetitive inspections of this AD.
The FAA disagrees. After reviewing
the S–92 AMM tasks, the FAA has
determined that the technical content
from Sikorsky S–92 Helicopter Alert
Service Bulletin ASB 92–62–009, Basic
Issue, dated February 6, 2019 (ASB 92–
62–009), and Sikorsky S–92 Helicopter
Alert Service Bulletin ASB 92–62–010,
Basic Issue, dated January 26, 2022 (92–
62–010) are not completely incorporated
into the AMM tasks. The visual
inspection instructions from ASB 92–
62–009 are not included in these tasks,
and the accomplishment instructions
from ASB 92–62–010 have some
elements that are missing from some of
the AMM tasks. Accordingly, the FAA
has determined that the
accomplishment instructions of ASB
92–62–009 and ASB 92–62–010 must be
done to correct the unsafe condition. In
addition, paragraph (f) of the AD
specifies to ‘‘comply with this AD . . .
unless already done.’’ Therefore, if some
of the actions required by this AD are
already done, only the remaining
required actions of this AD must be
accomplished in order to comply with
this AD.
Conclusion
The FAA reviewed the relevant data,
considered any comments received, 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. None of the changes will
increase the economic burden on any
operator.
Related Service Information Under 1
CFR Part 51
The FAA reviewed ASB 92–62–010,
which specifies a visual inspection of
the swashplate assembly to determine if
there are any cracks and initiates a 50hour recurring visual inspection. If
cracks are found, ASB 92–62–010
specifies replacing the swashplate
assembly. Dependent on accrued flight

time or suspicion of cracks, an FPI or
ECI is performed. ASB 92–62–010 also
specifies returning the swashplate
assembly, uniball bearing, trunnions,
and all attachment hardware to Sikorsky
for investigation if cracks are found.
This AD also requires ASB 92–62–
009, which the Director of the Federal
Register approved for incorporation by
reference as of February 18, 2022 (87 FR
2316, January 14, 2022).
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 the ADDRESSES section.
Differences Between This AD and the
Service Information
The applicability statement in this AD
does not identify airframe serial
numbers, whereas the effectivity of ASB
92–62–010 does. This AD affects all
swashplate assemblies P/N 92104–
15011–042 and P/N 92104–15011–043
regardless of delivery date, whereas the
effectivity of ASB 92–62–010 is for
those part-numbered swashplate
assemblies delivered as of January 26,
2022 (the issuance date of ASB 92–62–
010). ASB 92–62–009 specifies a onetime visual inspection of the swashplate
assembly; this AD requires a recurring
visual inspection of the swashplate
assembly to determine if any crack,
nick, dent, or scratch develops over
time. This AD does not require
returning parts to or contacting
Sikorsky, while ASB 92–62–009 and
ASB 92–62–010 specify performing
those actions.
lotter on DSK11XQN23PROD with RULES1
Costs of Compliance
The FAA estimates that this AD
affects 89 helicopters of U.S. registry.
The FAA estimates the following costs
to comply with this AD. Labor costs are
estimated at $85 per work-hour.
Visually inspecting a swashplate
assembly takes about 1.0 work-hour, for
an estimated cost of $85 per helicopter
and $7,565 for the U.S. fleet, per
inspection cycle.
Performing an ECI or FPI takes about
8.0 work-hours, for an estimated cost of
$680 per helicopter and $60,520 for the
U.S. fleet, per inspection cycle.
Replacing the swashplate assembly, if
required, takes about 16 work-hours and
parts cost about $389,720, for an
estimated cost of $391,080 per
helicopter.
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,
VerDate Sep<11>2014
15:53 May 24, 2023
Jkt 259001
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.
(a) Effective Date
This airworthiness directive (AD) is
effective June 29, 2023.
Regulatory Findings
The FAA has determined that 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.
(e) Unsafe Condition
This AD was prompted by the discovery of
a crack on the swashplate assembly inner
ring. The FAA is issuing this AD to detect
cracks that could result in fretting wear on
the shoulder that supports the clamp-up of
the uniball outer race. The unsafe condition,
if not addressed, could result in failure of the
swashplate assembly and subsequent loss of
control of the helicopter.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2022-02-01
for Sikorsky Aircraft Corporation Model S-92A helicopters with certain
part-numbered main rotor stationary swashplate assemblies (swashplate
assemblies) that had accumulated 1,600 or more total hours time-in-
service (TIS) installed. AD 2022-02-01 required visually inspecting the
swashplate assembly at specified intervals and depending on the
results, removing the swashplate assembly from service. Since the FAA
issued AD 2022-02-01, the FAA determined it was necessary to expand the
applicability and require more detailed inspections to address the
unsafe condition. This AD retains the actions of AD 2022-02-01, expands
the applicability, adds a detailed recurring visual inspection, and
requires either eddy current inspections (ECI) or
[[Page 33821]]
fluorescent penetrant inspections (FPI). The FAA is issuing this AD to
address the unsafe condition on these products.
DATES: This AD is effective June 29, 2023.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of June 29,

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2022-02-01, Amendment 39-21898 (87 FR 2316,
January 14, 2022), (AD 2022-02-01). AD 2022-02-01 applied to Sikorsky
Aircraft Corporation Model S-92A helicopters with a swashplate assembly
part number (P/N) 92104-15011-042 or P/N 92104-15011-043 that had
accumulated 1,600 or more total hours TIS, installed. The NPRM
published in the Federal Register on January 17, 2023 (88 FR 2558). The
NPRM was prompted by a notification of an in-service crack in a
swashplate assembly inner ring. The crack, discovered during a routine
inspection, extended between the uniball bore and near the right-hand
trunnion to servo attach bolt hole. In the NPRM, the FAA proposed to
continue to require, for swashplate assemblies that have accumulated
1,600 or more total hours TIS, a certain recurring visual inspection
and replacing the swashplate assembly if cracks are found. In the NPRM,
the FAA proposed to require accomplishing an FPI or ECI depending on
accrued flight time or suspicion of cracks. In the NPRM, the FAA also
proposed to expand the visual inspections required by AD 2022-02-01 and
revise the applicability statement of AD 2022-02-01.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from one commenter, Sikorsky Aircraft
Corporation. The following presents the comment received on the NPRM
and the FAA's response to the comment.
Request To Clarify Previous Actions for Compliance
Sikorsky Aircraft Corporation requested the FAA change paragraph
(f) of the AD to state, ``Comply with this AD within the compliance
times specified, unless already accomplished by Alert Service Bulletin.
Repetitive inspections incorporated into Sikorsky S-92 [Aircraft
Maintenance Manual] (AMM), Chapter 5, demonstrate compliance with the
repetitive inspections of this Airworthiness Directive.'' Sikorsky
Aircraft Corporation stated that it has issued two alert service
bulletins (ASBs) that introduce both a one-time inspection and
recurrent inspections for the existing part-numbered stationary
swashplate assemblies. In addition, Sikorsky Aircraft Corporation
stated that the recurrent inspections have been incorporated into the
Sikorsky S-92 AMM, Chapter 5 inspection requirements; and that the
introduction of this rule makes these inspections mandatory and the
original equipment manufacturer (OEM) agrees. However, Sikorsky
Aircraft Corporation stated that from the operator perspective, there
may be some confusion as to compliance with the AD. Since the ASBs and
Chapter 5 are in place, Sikorsky Aircraft Corporation stated that it
may be helpful to add language in the text of the AD explaining that
the AD is not introducing a new action if the operator is already
following the OEM instructions, which may prevent operators from
unnecessarily repeating inspections with which the operator already
complied. Lastly, Sikorsky Aircraft Corporation stated that operators
who incorporate repetitive inspections into their maintenance programs,
in this case the OEM Chapter 5, are demonstrating compliance with the
repetitive inspections of this AD.
The FAA disagrees. After reviewing the S-92 AMM tasks, the FAA has
determined that the technical content from Sikorsky S-92 Helicopter
Alert Service Bulletin ASB 92-62-009, Basic Issue, dated February 6,
2019 (ASB 92-62-009), and Sikorsky S-92 Helicopter Alert Service
Bulletin ASB 92-62-010, Basic Issue, dated January 26, 2022 (92-62-010)
are not completely incorporated into the AMM tasks. The visual
inspection instructions from ASB 92-62-009 are not included in these
tasks, and the accomplishment instructions from ASB 92-62-010 have some
elements that are missing from some of the AMM tasks. Accordingly, the
FAA has determined that the accomplishment instructions of ASB 92-62-
009 and ASB 92-62-010 must be done to correct the unsafe condition. In
addition, paragraph (f) of the AD specifies to ``comply with this AD .
. . unless already done.'' Therefore, if some of the actions required
by this AD are already done, only the remaining required actions of
this AD must be accomplished in order to comply with this AD.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, 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. None of the changes will
increase the economic burden on any operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed ASB 92-62-010, which specifies a visual inspection
of the swashplate assembly to determine if there are any cracks and
initiates a 50-hour recurring visual inspection. If cracks are found,
ASB 92-62-010 specifies replacing the swashplate assembly. Dependent on
accrued flight
[[Page 33822]]
time or suspicion of cracks, an FPI or ECI is performed. ASB 92-62-010
also specifies returning the swashplate assembly, uniball bearing,
trunnions, and all attachment hardware to Sikorsky for investigation if
cracks are found.
This AD also requires ASB 92-62-009, which the Director of the
Federal Register approved for incorporation by reference as of February
18, 2022 (87 FR 2316, January 14, 2022).
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 the ADDRESSES section.
Differences Between This AD and the Service Information
The applicability statement in this AD does not identify airframe
serial numbers, whereas the effectivity of ASB 92-62-010 does. This AD
affects all swashplate assemblies P/N 92104-15011-042 and P/N 92104-
15011-043 regardless of delivery date, whereas the effectivity of ASB
92-62-010 is for those part-numbered swashplate assemblies delivered as
of January 26, 2022 (the issuance date of ASB 92-62-010). ASB 92-62-009
specifies a one-time visual inspection of the swashplate assembly; this
AD requires a recurring visual inspection of the swashplate assembly to
determine if any crack, nick, dent, or scratch develops over time. This
AD does not require returning parts to or contacting Sikorsky, while
ASB 92-62-009 and ASB 92-62-010 specify performing those actions.
Costs of Compliance
The FAA estimates that this AD affects 89 helicopters of U.S.
registry. The FAA estimates the following costs to comply with this AD.
Labor costs are estimated at $85 per work-hour.
Visually inspecting a swashplate assembly takes about 1.0 work-
hour, for an estimated cost of $85 per helicopter and $7,565 for the
U.S. fleet, per inspection cycle.
Performing an ECI or FPI takes about 8.0 work-hours, for an
estimated cost of $680 per helicopter and $60,520 for the U.S. fleet,
per inspection cycle.
Replacing the swashplate assembly, if required, takes about 16
work-hours and parts cost about $389,720, for an estimated cost of
$391,080 per helicopter.
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 has determined that 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.
