Airworthiness Directives; Dassault Model Mystere-Falcon 200, Fan Jet Falcon, and Mystere-Falcon 20 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all Dassault Model Mystere-Falcon 200, Fan Jet Falcon, and Mystere-Falcon 20 series airplanes, that requires repetitive inspections to detect cracks at the attaching holes of the wing-to- fuselage fairings and to ensure tightness of the attaching screws; and repair of any discrepancy. This amendment also requires installation of cupwashers under the vertical seams of the upper fairings. 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 loss of the wing-to-fuselage upper fairings during flight, which could result in the fairings impacting the engines or tail sections, and consequent reduced controllability of the airplane.
