Airworthiness Directives; Gulfstream Aerospace LP Airplanes

FAA / Federal Register · 2026-09170

The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP (GALP) Model Gulfstream G280 airplanes. This AD was prompted by reports of the accumulation of water in electrical connectors located in the aft fuselage directly below the empennage, resulting in empennage flight control related crew alerting system (CAS) messages. This AD requires retrofitting the flight controls empennage electrical harness. The FAA is issuing this AD to address the unsafe condition on these products.
