Airworthiness Directives; AlliedSignal Inc. TFE731-3 Series Turbofan Engines

Traduction automatique locale · Langue originale de la source

Résumé

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