Administration (FAA), DOT.
ACTION: Final rule.
AGENCY:
We are superseding
Airworthiness Directive (AD) 2017–14–
03 for Sikorsky Aircraft Corporation
(Sikorsky) Model S–92A helicopters. AD
2017–14–03 required an inspection and
reduced the retirement lives of certain
landing gear components. This new AD
retains the requirements of AD 2017–
14–03, reduces the retirement lives of
additional landing gear components,
and requires repeating the inspection.
This AD was prompted by a revised
analysis of the fatigue life of the landing
gear. The actions of this AD are
intended to prevent an unsafe condition
on these products.
DATES: This AD is effective October 30,
2018.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of August 11, 2017 (82 FR 34838, July
27, 2017).

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to remove AD 2017–14–03,
Amendment 39–18947 (82 FR 34838,
July 27, 2017) (AD 2017–14–03) and add
a new AD. AD 2017–14–03 applied to
Sikorsky Model S–92A helicopters and
required inspecting and reducing the
retirement lives of certain landing gear
components. AD 2017–14–03 was
prompted by Sikorsky’s updated fatigue
analysis of the nose and main landing
gear, which revealed that certain
components required a reduced service
life and one component required a
repetitive visual and ultrasonic
inspection. When we issued AD 2017–
14–03, we determined that the age of the
existing U.S. fleet and the compliance
time for the repetitive inspection would
allow enough time for notice and public
comments on some actions.

Register on May 17, 2018 (83 FR 22883).

FAA’s Determination
We have reviewed the relevant
information and determined that an
unsafe condition exists and is likely to
exist or develop on other helicopters of
this same type design and that air safety
and the public interest require adopting
the AD requirements as proposed.
Related Service Information Under 1
CFR Part 51
We reviewed Ultrasonic Inspection
Technique No. UT 5077, Revision 0,
dated July 25, 2014 (UT 5077). UT 5077
contains the inspection method,
equipment and materials, calibration,
and inspection procedure for
performing an ultrasonic inspection of
nose gear actuator fitting part number
(P/N) 92209–01101–101.
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.
Other Related Service Information
We also reviewed Sikorsky S–92
Helicopter Alert Service Bulletin 92–
32–004, Basic Issue, dated January 30,
2015 (ASB). The ASB describes
procedures for conducting a visual
inspection of the nose landing gear
(NLG) airframe fitting assembly and an
ultrasonic inspection by following the
procedures in UT 5077.
Costs of Compliance
We estimate that this AD affects 80
helicopters of U.S. Registry.

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.
We are 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
We have 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) Is not a ‘‘significant rule’’ under
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation
in Alaska to the extent that a regulatory
distinction is required, and
(4) 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.
List of Subjects in 14 CFR Part 39

Safety.
Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
■
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by
removing Airworthiness Directive (AD)
2017–14–03, Amendment 39–18947 (82
FR 34838, July 27, 2017), and adding the
following new AD:
■
2018–19–09 Sikorsky Aircraft Corporation
(Sikorsky): Amendment 39–19409;
Docket No. FAA–2018–0439; Product
Identifier 2016–SW–074–AD.
(a) Applicability
This AD applies to Sikorsky Model S–92A
helicopters, certificated in any category.
(b) Unsafe Condition
This AD defines the unsafe condition as
fatigue failure of the landing gear. This
condition could result in failure of the
landing gear and subsequent damage to and
loss of control of the helicopter.
(c) Affected ADs
This AD replaces AD 2017–14–03,
Amendment 39–18947 (82 FR 34838, July 27,
2017).
(d) Effective Date
This AD becomes effective October 30,
2018.
(e) Compliance
You are responsible for performing each
action required by this AD within the
specified compliance time unless it has
already been accomplished prior to that time.
(f) Required Actions
(1) Before further flight, remove from
service any part that has accumulated the
number of landing cycles listed in Table 1 to
paragraph (f)(1) of this AD. Thereafter,
remove from service any part before
accumulating the number of landing cycles
listed in Table 1 to paragraph (f)(1) of this
AD. For purposes of this AD, a landing cycle
is counted anytime the helicopter lifts off
into the air and then lands again regardless
of the duration of the landing and regardless
of whether the engine is shut down. If the
number of landing cycles in unknown,
multiply the number of hours time-in-service
by 4.5 to determine the number of landing
cycles.

was prompted by Sikorsky's updated fatigue analysis of the nose and
main landing gear, which revealed that certain components required a
reduced service life and one component required a repetitive visual and
ultrasonic inspection. When we issued AD 2017-14-03, we determined that
the age of the existing U.S. fleet and the compliance time for the
repetitive inspection would allow enough time for notice and public
comments on some actions.
The NPRM published in the Federal Register on May 17, 2018 (83 FR
22883). The NPRM proposed to retain the actions in AD 2017-14-03,
reduce the life limits of additional components, and require repeating
the visual and ultrasonic inspections. These actions are intended to
detect and prevent cracks or failure of a landing gear component, which
could result in damage and loss of control of the helicopter.
Comments
We gave the public the opportunity to participate in developing
this AD, but we did not receive any comments on the NPRM.
FAA's Determination
We have reviewed the relevant information and determined that an
unsafe condition exists and is likely to exist or develop on other
helicopters of this same type design and that air safety and the public
interest require adopting the AD requirements as proposed.

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.
We are 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
We have 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) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska to the extent
that a regulatory distinction is required, and
(4) 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.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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 removing Airworthiness Directive (AD)
2017-14-03, Amendment 39-18947 (82 FR 34838, July 27, 2017), and adding
the following new AD:
2018-19-09 Sikorsky Aircraft Corporation (Sikorsky): Amendment 39-
19409; Docket No. FAA-2018-0439; Product Identifier 2016-SW-074-AD.
(a) Applicability
This AD applies to Sikorsky Model S-92A helicopters,
certificated in any category.
(b) Unsafe Condition
This AD defines the unsafe condition as fatigue failure of the
landing gear. This condition could result in failure of the landing
gear and subsequent damage to and loss of control of the helicopter.
(c) Affected ADs
This AD replaces AD 2017-14-03, Amendment 39-18947 (82 FR 34838,
July 27, 2017).
(d) Effective Date
This AD becomes effective October 30, 2018.
(e) Compliance
You are responsible for performing each action required by this
AD within the specified compliance time unless it has already been
accomplished prior to that time.
(f) Required Actions
(1) Before further flight, remove from service any part that has
accumulated the number of landing cycles listed in Table 1 to
paragraph (f)(1) of this AD. Thereafter, remove from service any
part before accumulating the number of landing cycles listed in
Table 1 to paragraph (f)(1) of this AD. For purposes of this AD, a
landing cycle is counted anytime the helicopter lifts off into the
air and then lands again regardless of the duration of the landing
and regardless of whether the engine is shut down. If the number of
landing cycles in unknown, multiply the number of hours time-in-
service by 4.5 to determine the number of landing cycles.
