Incident Overview
Description
The owner of the Boeing 707 freighter had leased the aircraft to a Belgian charter broker around June 1998 to operate fish charter flights between Mwanza and Vienna. The aircraft was in fact seen on many other airports, Bratislava, Ostrava, and Lumumbashi for instance. At the time of the accident the plane is understood to have had a long list of 32 faults that needed urgent repair. Problems included a limited EGT of no. 1 and 4 engines; no. 3 engine constant speed drive (CSD) gearbox was consuming a ‘massive amount of oil’; no. 1 engine CSD generator missing; no. 2 engine required bleed on takeoff and above FL330; left wing leading edge cracked and leaking; no. 4 fuel tank and reserve tank gauge not working. On February 7 the plane was to fly to N’Djamena. During the takeoff roll the no. 2 and 3 engines failed. The takeoff was aborted, but the 707 overran the runway and came to rest 200 m past the runway end.
Primary Cause
Multiple mechanical failures and operational errors, including a combination of engine faults, a malfunctioning CSD gearbox, and a lack of critical system functionality.Multiple mechanical failures and operational errors, including a combination of engine faults, a malfunctioning CSD gearbox, and a lack of critical system functionality.Share on:
