Airworthiness Directive 2002-23-12
one-timeAirworthiness Directives; Rolls-Royce Limited, Aero Division-Bristol, S.N.E.C.M.A. Olympus 593 Mk. 610-14-28 Turbojet Engines
What this AD requires
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.
Which aircraft AD 2002-23-12 applies to
Applies specifically to HPC stage 5 disks P/N B510911 SN J14CA and P/N B510909 SN JZJ66 on RR Olympus 593 engines; one-time inspection before further flight per RR Olympus 593 MSB OL.593-72-8951-364 Rev 7, dated November 23, 2001; cracked disks must be replaced.
Whether AD 2002-23-12 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
