Incident Overview
On February 7, an aircraft operating a ferry flight to N'Djamena experienced a dual engine failure during the takeoff roll. The takeoff was aborted, but the aircraft could not be stopped within the remaining runway distance. It overran the runway, lost its nose gear, and came to rest approximately 200 meters past the runway end. All seven occupants evacuated without injury. The aircraft sustained damage beyond repair.
Background
The aircraft had been leased to a Belgian charter broker around June 1998 to operate fish charter flights between Mwanza and Vienna. It was also observed at airports in Bratislava, Ostrava, and Lubumbashi. At the time of the accident, the aircraft had a documented list of 32 faults requiring urgent repair.
Known Technical Issues
Reported problems included limited exhaust gas temperature (EGT) on engines 1 and 4; the constant speed drive (CSD) gearbox on engine 3 was consuming a 'massive amount of oil'; the CSD generator on engine 1 was missing; engine 2 required bleed air on takeoff and above flight level 330; the left wing leading edge was cracked and leaking; and the gauges for fuel tank 4 and the reserve tank were not functioning.
Ferry Decision
On February 7, a decision was made to ferry the aircraft to N'Djamena despite the outstanding maintenance issues. During the subsequent takeoff, engines 2 and 3 failed, leading to the aborted takeoff and overrun.
