Airworthiness Directives; Dassault Aviation Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 6X and FALCON 7X airplanes, and certain Model FALCON 900EX and FALCON 2000EX airplanes. This proposed AD was prompted by reports of passenger seats sliding without passenger input, which subsequent investigation determined to be caused by the ring brakes and ring brake housing being out of allowed adjustment tolerances, failing to lock the seat in place. This proposed AD would require an inspection of each affected seat for discrepancies and applicable on-condition actions. This proposed AD would also limit the installation of affected seats under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.
