Abstract
The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation (Gulfstream) Model GV and GV-SP airplanes. This AD was prompted by the omission of a life limit in the airworthiness limitations section (ALS) of the maintenance manual for a certain main landing gear (MLG) trunnion pin. This AD requires revising the ALS of the existing instructions for continued airworthiness (ICA) or inspection program for the airplane to establish a life limit for the affected MLG trunnion pin. 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
Gulfstream Aerospace Corporation (Gulfstream) Model GV and GV-SP
airplanes. This AD was prompted by the omission of a life limit in the
airworthiness limitations section (ALS) of the maintenance manual for a
certain main landing gear (MLG) trunnion pin. This AD requires revising
the ALS of the existing instructions for continued airworthiness (ICA)
or inspection program for the airplane to establish a life limit for
the affected MLG trunnion pin. The FAA is issuing this AD to address
the unsafe condition on these products.
DATES: This AD is effective February 28, 2023.
ADDRESSES:
AD Docket: You may examine the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-1305; or in person at Docket Operations between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
docket contains this final rule, any comments received, and other
information. The address for Docket Operations is U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,

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 Gulfstream Model GV
and GV-SP airplanes. The NPRM published in the Federal Register on
October 27, 2022 (87 FR 65018). The NPRM was prompted by a report
indicating a life limit for replacing MLG trunnion pin part number (P/
N) 1159SCL566-17 had been omitted from the ALS of the maintenance
manual for Model GV and GV-SP airplanes. Gulfstream revised the ALS for
the applicable airplanes to establish a life limit of 20,000 flight
cycles for the affected MLG trunnion pin. A trunnion pin remaining in
service beyond its life limit could lead to fracture and failure of the
trunnion pin. This condition, if not addressed, could result in MLG
failure and could lead to a runway excursion.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
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.
None of the changes will increase the economic burden on any operator.
Other Related Service Information
The FAA reviewed Gulfstream GV Aircraft Maintenance Manual,
Revision 55, dated March 15, 2022; Gulfstream G550 Aircraft Maintenance
Manual, Revision 36, dated March 15, 2022; and Gulfstream G500-5000
Aircraft Maintenance Manual, Revision 36, dated March 15, 2022. The
service information adds a life limit for MLG trunnion pin P/N
1159SCL566-17.
Costs of Compliance
The FAA estimates that this AD affects 582 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

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.

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 adding the following new airworthiness
directive:
2023-02-02 Gulfstream Aerospace Corporation: Amendment 39-22309;
Docket No. FAA-2022-1305; Project Identifier AD-2022-00913-T.
(a) Effective Date
This airworthiness directive (AD) is effective February 28,
2023.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Gulfstream Aerospace Corporation Model GV and
GV-SP airplanes, all serial numbers, certificated in any category.

(e) Unsafe Condition
This AD was prompted by the omission of a life limit in the
airworthiness limitations section (ALS) for a certain main landing
gear (MLG) trunnion pin. The FAA is issuing this AD to prevent a MLG
trunnion pin from remaining in service beyond its life limit. This
unsafe condition, if not addressed, could result in MLG failure and
could lead to a runway excursion.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Incorporation of ALS Revisions
Within 12 months after the effective date of this AD, revise the
existing ALS of the instructions for continued airworthiness or
aircraft inspection program for your airplane by establishing a life
limit of 20,000 flight cycles for each MLG trunnion pin part number
(P/N) 1159SCL566-17.
Note 2 to paragraph (g): The life limit in paragraph (g) of this
AD is contained in table 5 in Section 05-10-10 of the Gulfstream V
Aircraft Maintenance Manual, Revision 55, dated March 15, 2022;
table 4 in Section 05-10-10 of the Gulfstream G500-5000 Aircraft
Maintenance Manual, Revision 36, dated March 15, 2022; and table 4
in Section 05-10-10 of the Gulfstream G550 Aircraft Maintenance
Manual, Revision 36, dated March 15, 2022.
