Models named: GVIII-G700, GVIII-G800. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Gulfstream Aerospace Corporation airplanes, certificated in any category, identified in paragraphs (c)(1) and (2) of this AD. (1) Model GVIII-G700 airplanes, serial numbers (S/Ns) 87002 through 87049 inclusive, 87053, and 87076. (2) Model GVIII-G800 airplanes, S/Ns 88002 through 88014 inclusive.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Before further flight: Except as specified by paragraph (h) of this AD, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Gulfstream GVIII-G700 Alert Customer Bulletin No. 001, dated June 16, 2026; or Gulfstream GVIII-G800 Alert Customer Bulletin No. 001, dated June 16, 2026; as applicable.
Unsafe condition
This AD was prompted by a report indicating that a hollow pin cap on the right engine aft thrust strut was found broken due to a missing sleeve bushing. The FAA is issuing this AD to address an improperly installed engine thrust strut that could compromise the structural integrity of the engine mount system and lead to failure of the engine mount system. The unsafe condition, if not addressed, could result in an in-flight separation of the engine from the airplane, leading to loss of control of the airplane.
Affected ADs
None.
