Airworthiness Directive · Amendment 39-13470 · Dassault Model Falcon 900EX Series Airplanes
Dassault Model Falcon 900EX Series Airplanes
Model Falcon 900EX series airplanes, serial numbers 1 through 60 inclusive; certificated in any category; except those on which Dassault Modifications M2754 and M2925, identified in Dassault Service Bulletin F900EX-103, Revision 1, dated October 16, 2002, have been accomplished.
This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Falcon 900EX series airplanes, that requires modification of the front attachment area of the No. 2 engine. This action is necessary to prevent failure of the fail-safe lugs of the hoisting plate of the forward engine mount, and subsequent cracking of the pick-up folded sheet of the pylon forward rib. Such cracking could rupture the mast case box, which could result in loss of the two forward engine mounts and consequent separation of the engine from the airplane. This action is intended to address the identified unsafe condition.
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.
