Dassault SUBJECT: Front Area Of No. 2 Engine SUMMARY: 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.
This AD becomes effective March 17, 2004.
