de Havilland Model DHC-8-100, -200, and -300 Series Airplanes
Model DHC-8-100, -200, and -300 series airplanes; as listed in Bombardier Alert Service Bulletin S.B. A8-28-20, Revision `A,' dated September 10, 1996; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain de Havilland Model DHC-8-100, -200, and -300 series airplanes, that requires repetitive inspections of certain refuel/defuel tube assemblies in the engine nacelles for fuel leakage, and corrective action, if necessary. This amendment will also require eventual modification of all tube assemblies, which will terminate the repetitive inspections. 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 fuel leaks and consequent increased risk of engine fires.
