Airworthiness Directives; Dassault Model Mystere-Falcon 50 and 900 Series Airplanes, Falcon 900EX Series Airplanes, and Falcon 2000 Series Airplanes

Resumo

This amendment adopts a new airworthiness directive (AD), applicable to all Dassault Model Mystere-Falcon 50 and 900 series airplanes, Falcon 900EX series airplanes, and Falcon 2000 series airplanes, that requires revising the Airplane Flight Manual to provide the flight crew with certain instructions associated with the onset of stall warning. This amendment also requires repetitive inspections to detect discrepancies of the hinge pin assemblies of the rear horizontal stabilizer, and corrective actions, if necessary. For certain airplanes, this amendment also requires replacement of the hinge pin assemblies with new, improved parts. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent excessive movement and consequent deformation of the hinge pin assemblies of the rear horizontal stabilizer, which could result in flutter and possible failure of the rear horizontal stabilizer.
