Abstract
This amendment adopts a new airworthiness directive (AD), applicable to AlliedSignal Inc. (formerly Garrett Turbine Engine Company) TFE731-3 series turbofan engines, that requires the removal of suspect low pressure turbine (LPT) disks due to their susceptibility to creep fatigue. This amendment is prompted by reports of LPT disks that have separated through the disk web due to creep fatigue. The actions specified by this AD are intended to prevent an LPT disk web separation, which may result in an uncontained engine failure and damage to the aircraft.
