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

This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Mystere-Falcon 900, Falcon 900EX, and Falcon 2000 series airplanes, that requires replacement of the elevator auxiliary artificial feel unit (AFU) with a new elevator auxiliary AFU. 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 failure of the elevator auxiliary AFU. Failure of an AFU, coupled with a control linkage disconnection upstream of the servo actuator and downstream of the main AFU, could result in reduced controllability of the airplane.
