ACTION: Final rule. AGENCY: 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 your existing instructions for continued airworthiness (ICA) or inspection program for the airplane to establish a life limit of 20,000 flight cycles 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 January 14, 2022.

SUPPLEMENTARY INFORMATION: pin remaining in service beyond its fatigue life could lead to fracture and failure of the trunnion pin. In the NPRM, the FAA proposed to require revising the ALS of your ICA or inspection program for the airplane to establish a life limit of 20,000 flight cycles for the affected MLG trunnion pin. The FAA is issuing this AD to prevent MLG failure, which 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 costs. 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. This AD is adopted as proposed in the NPRM. Background Related Service Information 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 Aerospace Corporation (Gulfstream) Model GV and GV–SP airplanes. The NPRM published in the Federal Register on September 17, 2021 (86 FR 51842). The NPRM was prompted by notification from Gulfstream that a life limit for replacing MLG trunnion pin part number (P/N) 1159SCL566–15 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 The FAA reviewed Gulfstream GV Aircraft Maintenance Manual, Revision 53, dated March 15, 2021; Gulfstream G550 Aircraft Maintenance Manual, Revision 34, dated March 15, 2021; and Gulfstream G500–5000 Aircraft Maintenance Manual, Revision 34, dated March 15, 2021. For the applicable marketing designation specified on each document, the revised service information adds a life limit for MLG trunnion pin P/N 1159SCL566–15. Costs of Compliance The FAA estimates that this AD affects 516 airplanes of U.S. registry.

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 your existing instructions for continued airworthiness (ICA) 
or inspection program for the airplane to establish a life limit of 
20,000 flight cycles 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 January 14, 2022.

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 
Aerospace Corporation (Gulfstream) Model GV and GV-SP airplanes. The 
NPRM published in the Federal Register on September 17, 2021 (86 FR 
51842). The NPRM was prompted by notification from Gulfstream that a 
life limit for replacing MLG trunnion pin part number (P/N) 1159SCL566-
15 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 fatigue life could lead to fracture and failure of the trunnion 
pin.
    In the NPRM, the FAA proposed to require revising the ALS of your 
ICA or inspection program for the airplane to establish a life limit of 
20,000 flight cycles for the affected MLG trunnion pin. The FAA is 
issuing this AD to prevent MLG failure, which 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 costs.

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. This AD is 
adopted as proposed in the NPRM.

Related Service Information

    The FAA reviewed Gulfstream GV Aircraft Maintenance Manual, 
Revision 53, dated March 15, 2021; Gulfstream G550 Aircraft Maintenance 
Manual, Revision 34, dated March 15, 2021; and Gulfstream G500-5000 
Aircraft Maintenance Manual, Revision 34, dated March 15, 2021. For the 
applicable marketing designation specified on each document, the 
revised service information adds a life limit for MLG trunnion pin P/N 
1159SCL566-15.

Costs of Compliance

    The FAA estimates that this AD affects 516 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:

[[Page 70368]]

    (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.
