Rolls-Royce Limited., Aero Division-Bristol, S.N.E.C.M.A. Olympus 593 Mk. 610-14-28 Turbojet Engines
This airworthiness directive (AD) is applicable to Rolls-Royce Limited, Aero Division-Bristol, S.N.E.C.M.A. (RR) Olympus 593 Mk. 610-14-28 turbojet engines, serial numbers (SN's) CBE . 021 to CBE . 094 inclusive, and CBX . 101 and above. These engines are installed on, but not limited to BAe/SNIAS Concorde Type 1 airplanes.
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.
