## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Model GV and certain Model GV-SP series airplanes. This AD requires a one-time inspection of the left and right aileron and elevator actuators to determine the part and serial numbers of each actuator, repetitive inspections of suspect actuators to detect broken damper shafts, and replacement of any actuator having a broken damper shaft. This AD also requires that operators report any broken damper shaft they find to the FAA. This AD also requires a terminating action for the repetitive inspections. This AD results from reports of broken or cracked damper shafts within the aileron and elevator actuator assemblies. We are issuing this AD to prevent broken damper shafts, which could result in locking of an aileron or elevator actuator (hard- over condition), which would activate the hard-over protection system (HOPS), resulting in increased pilot workload and consequent reduced controllability of the airplane.
