Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to Honeywell International, Inc., (formerly AlliedSignal, Inc. and Textron Lycoming) ALF502L-2, ALF502L-2C, ALF502R-3 and ALF502R-3A series turbofan engines. This action requires inspection of the flow divider primary, secondary, and drain tube assemblies for security and proper clamping. This amendment is prompted by a fire in the engine nacelle of an ALF502L-2C powered airplane caused by fracture of the flow divider left primary fuel tube, due to high-cycle fatigue resulting from a missing support clamp. The actions specified in this AD are intended to prevent fire in the engine nacelle, in-flight shutdown, and possible damage to the engine.
