## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to Rolls-Royce Limited, Aero Division-Bristol, S.N.E.C.M.A (RR) Olympus 593 Mk. 610-14-28 turbojet engines. This action requires a one-time fluorescent penetrant inspection (FPI) of certain rebroached stage 5 high pressure compressor (HPC) disks, inspecting for cracks, and if necessary, removing cracked disks from service. This amendment is prompted by a manufacturer's analysis that concluded that the rebroaching process failed to achieve the anticipated life before being rejected for cracks and that the original cracks are not being removed. The actions specified in this AD are intended to prevent failure of the HPC stage 5 disk which could result in an uncontained engine failure and damage to the airplane.
