Plain English Summary

2/10 complexity

AD/TPE 331/48 cancels a previous airworthiness directive about spline wear on the Fuel Control Unit drive shaft for AlliedSignal (Garrett/AiResearch) TPE331 engines. (Requirement: CANCELLED.) Operators may elect to add or retain an Emergency Procedures reference in the approved flight manual; the AD cross-references FAA AD 94-26-07. (Note.)

The cancellation is based on advice that affected drive shafts have been removed from service and that the inspection requirements are now captured in the engine maintenance manual schedule, so maintainers follow the engine MM rather than this AD. (Background.)
