Airworthiness Directives; Dassault Model Mystere-Falcon 50 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all Dassault Model Mystere-Falcon 50 series airplanes, that requires a one-time inspection of the clearances around the wiring harnesses of the right-hand electrical cabinet, and readjustment of the clearances, if necessary. This amendment will also require installation of protective strips on the wiring harnesses and equipment supports. This amendment is prompted by issuance of mandatory continued airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent interference between the wiring harnesses and adjacent equipment, support brackets, and structural elements, which could cause an electrical short circuit resulting in fire, and consequent loss of electrical power to essential flight systems.
