## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Fan Jet Falcon series airplanes; Model Mystere-Falcon 20, 50, 200, and 900 series airplanes; and Model Falcon 10, 900EX, and 2000 series airplanes, that requires a functional test of the passenger oxygen masks, determination of the part number of the installed oxygen mask bags; and corrective action, 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 ensure that proper plastic bags of the passenger oxygen masks are installed, and that the masks are functioning properly. Improper plastic bags that have cracks or improperly functioning masks could result in insufficient oxygen to passengers in the event of rapid depressurization of the airplane.
