Airworthiness Directives; Fokker Model F27 Series Airplanes Equipped With Rolls-Royce 532-7 ``Dart 7'' (RDa-7) Series Engines

This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F27 series airplanes, that requires revising the Airplane Flight Manual (AFM) to provide the flightcrew with modified operational procedures to ensure continuous operation with the high pressure cock (HPC) levers in the lockout position. 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 burnout of the engines during flight by ensuring that the HPC levers are in a permanent lockout position.
