Airworthiness Directive · Amendment 39-13568 · Dassault Model Mystere-Falcon 50, Mystere-Falcon 900, and Falcon 900 EX Series Airplanes
Dassault Model Mystere-Falcon 50, Mystere-Falcon 900, and Falcon 900 EX Series Airplanes
Model Mystere-Falcon 50 series airplanes with a Stormscope antenna installed between frames 22 and 23 by Dassault modification M2208 or by a DFJ Little Rock modification, except on airplanes on which Dassault modification M2838 has been performed; and Model Mystere-Falcon 900 and Falcon 900EX series airplanes with a Stormscope antenna installed between frames 23 and 24 by Dassault modification M2993 or by a DFJ Little Rock modification, except airplanes on which Dassault modification M3498 has been performed; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Mystere-Falcon 50, Mystere-Falcon 900, and Falcon 900 EX series airplanes, that requires installing a shield plate over the tank structure above the Stormscope antenna and replacing the Stormscope antenna plug connector with a new connector. This action is necessary to prevent puncture of the fuel tank in the event of a belly landing, which could result in a post-landing fire if fuel leaking from the tank makes contact with the sparks from the airplane sliding on the ground. 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.
