Airworthiness Directives; Saab Model SAAB 2000 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB 2000 series airplanes, that requires inspection of the two-way check valve on the engine fire extinguishing system for discrepancies, and corrective action, if necessary. 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 discrepancies of the check valve, which could result in improper functioning of the engine fire extinguishing system.
