## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Falcon 2000 series airplanes, that requires a detailed inspection for interference between the safety-lock hooks and upper cowls, and corrective action, if necessary. This amendment also requires modification of the attachment supports of the inner locking hooks; and a detailed inspection of the safety-lock hooks on the lower engine cowl for proper operation and for clearance between the outer edges of the upper and lower cowls; and corrective actions, if necessary. 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 unintended disengagement of the engine cowl hooks during ground maintenance, which could result in in-flight loss of an engine cowl from the airplane and possible damage to the airplane and persons or property on the ground.
