## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to Allison Engine Company, Inc. AE 3007A and AE 3007C series turbofan engines. This AD requires the removal from service of certain turbine wheels before exceeding new, reduced cyclic life limits. This amendment is prompted by a refined life analysis that was performed by the manufacturer. The actions specified by this AD are intended to prevent an uncontained turbine wheel failure, which could result in damage to the airplane.
