Plain English Summary

2/10 complexity

This is a mandatory safety order for aircraft operators using specific AlliedSignal (Lycoming) turbine engines (models ALF502 and LF507). What it requires: Owners must inspect the fuel manifolds—metal components that deliver fuel to the engine—on these specific engine models. Why it's needed: Reports showed these manifolds were developing cracks that caused fuel leaks, creating a serious risk of in-flight fires. How to comply: Follow the technical inspection steps outlined in AlliedSignal Service Bulletin ALF/LF 73-1002. If you replace both the left and right fuel manifolds with the improved parts (part numbers 2-163-620-37 and -38), you permanently satisfy this requirement. Who it affects: Any aircraft operator with these engine models that have the affected fuel manifolds installed. Compliance is mandatory to keep the aircraft airworthy.
