AD NUMBER:  2002-23-12
MANUFACTURER: Rolls Royce
SUBJECT:  Airworthiness Directive 2002-23-12
SUMMARY:  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.

AD NUMBER:  2002-26-04
MANUFACTURER: Rolls Royce
SUBJECT:  Airworthiness Directive 2002-26-04
SUMMARY:  This amendment adopts a new airworthiness directive (AD) that is applicable to certain serial number (SN) Rolls-Royce Limited, Aero Division-Bristol, S.N.E.C.M.A. (RR) Olympus 593 Mk.610-14-28 turbojet engines, installed in BAe/SNIAS Concorde Type 1 airplanes. This action requires second stage fuel pump endurance bench-testing if the pump has not yet accumulated 50 flight hours since last installed and the bearing assembly and or the rotating assembly were removed or re-fitted during last pump removal. This amendment is prompted by a report of second stage fuel pumps that were not endurance bench-tested after having the bearing assembly and or the rotating assembly removed or re-fitted, and then installed on engines in service. The actions specified in this AD are intended to prevent a fuel leak resulting in a sustained engine fire.
