The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model GVIII-G700 and GVIII- G800 airplanes. This AD was prompted by a report indicating that a hollow pin cap on the right-side engine aft thrust strut mount interface was found broken due to a missing sleeve bushing. This AD requires a visual inspection of the upper surface of the engine mount to the forward and aft thrust strut mount at the hollow pin head interface, of the left and right engines, for evidence of movement or distress; an inspection of the forward and aft thrust strut mount hardware to ensure the sleeve bushing, nut, washers, and cotter pins are properly installed; and applicable corrective actions. The FAA previously sent an emergency AD to all known U.S. owners and operators of these airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
