Airworthiness Directive · Amendment 39-12964 · Dassault Model Falcon 900EX and Mystere Falcon 900 Series Airplanes
Dassault Model Falcon 900EX and Mystere Falcon 900 Series Airplanes
Superseded. A later AD replaced this one: AD 2016-01-16. Comply with the one in force.
Model Falcon 900EX, serial numbers 04 and up, and Mystere Falcon 900 series airplanes, serial numbers 161 and up; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Falcon 900EX and Mystere Falcon 900 series airplanes, that requires repetitive operational tests of the flap asymmetry detection system to verify proper functioning, and repair, if necessary; repetitive replacement of the inboard flap jackscrews with new or reconditioned jackscrews; and repetitive measurement of the screw/nut play of the jackscrews on the inboard and outboard flaps to detect discrepancies, and corrective action, if necessary. This amendment also requires revision of the Airplane Flight Manual. 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 jamming of the flap jackscrews during the approach to landing, which could result in inability to move the flaps or an asymmetric flap condition, and consequent reduced controllability of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
