Abstract
This amendment adopts a new airworthiness directive (AD), applicable to AlliedSignal Aerospace (formerly Garrett Auxiliary Power Division and Garrett Turbine Engine Co.) GTCP85 series auxiliary power units (APU), that requires modifying the APU to install an exhaust centerbody. This amendment is prompted by reports of two uncontained APU failures where turbine wheel fragments exited the APU exhaust axially and damaged the aircraft. The actions specified by this AD are intended to prevent an axially uncontained APU failure and damage to the aircraft.
