Airworthiness Directive · Amendment 39-10480 · Gulfstream Model GV Series Airplanes
Gulfstream Model GV Series Airplanes
Model GV series airplanes, serial numbers 501 and 504 through 540 inclusive, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Gulfstream Model GV series airplanes. This action requires inspections and functional tests of the elevator Hardover Prevention System (HOPS) to detect any miswiring of electrical connectors, correction of any discrepancy found, and eventual modification of the HOPS wiring. This amendment is prompted by reports of incorrect matching of electrical connectors to the hydraulic deactivation valves of the elevator HOPS. The actions specified in this AD are intended to prevent the incorrect operation of the elevator HOPS, which could result in loss of control of the airplane.
