Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA has received 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 Models 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 unaddressed, could result in MLG failure and could lead to a runway excursion. FAA’s Determination The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. 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. Proposed AD Requirements in This NPRM This proposed AD would require revising the ALS of the existing ICA or inspection program for the airplane to establish a life limit of 20,000 flight cycles for MLG trunnion pin P/N 1159SCL566–17.

receives that is not specifically designated as CBI will be placed in 
the public docket for this rulemaking.

Background

    The FAA has received 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 Models 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 
unaddressed, could result in MLG failure and could lead to a runway 
excursion.

FAA's Determination

    The FAA is issuing this NPRM after determining that the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

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.

Proposed AD Requirements in This NPRM

    This proposed AD would require revising the ALS of the existing ICA 
or inspection program for the airplane to establish a life limit of 
20,000 flight cycles for MLG trunnion pin P/N 1159SCL566-17.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 582 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed 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

    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:

[[Page 65020]]

    (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:

Gulfstream Aerospace Corporation: Docket No. FAA-2022-1305; Project 
Identifier AD-2022-00913-T.

 (a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by December 12, 2022.

(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.

    Note 1 to paragraph (c): Model GV-SP airplanes are also referred 
to by the marketing designations G500, G550, and G500-5000.

(d) Subject

    Joint Aircraft System Component (JASC) Code 3200, Landing Gear 
System.

(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 fatigue life. 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 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.

 (h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Atlanta ACO Branch, FAA, has the authority to 
approve AMOCs for this AD, if requested using the procedures found 
in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request 
to your principal inspector or responsible Flight Standards Office, 
as appropriate. If sending information directly to the manager of 
the certification office, send it to the attention of the person 
identified in paragraph (i)(1) of this AD.
