Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes

FAA / Federal Register · 2021-24082

The FAA proposes to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation (Gulfstream) Model GV and GV- SP airplanes. This proposed AD results from corrosion of the horizontal stabilizer lower bonded skin assemblies. This proposed AD would require inspecting the horizontal stabilizer lower skin and associated bonded doublers and bonded stringers, repairing the area susceptible to corrosion, and incorporating revisions to the airworthiness limitations section (ALS) in the existing aircraft maintenance manual (AMM). The FAA is proposing this AD to address the unsafe condition on these products.
