## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to CFE Company model CFE738-1-1B turbofan engines, that requires new life limits for certain HPC rotor components in all engines. This amendment is prompted by a reduction in the calculated service life of certain compressor rotor rotating parts to values below currently approved service lives. The actions specified by this AD are intended to prevent failure of certain HPC rotor components, which could result in an uncontained engine failure and damage to the airplane.
