Boeing 707

The aircraft was completing a cargo flight from Belém to São Paulo with an intermediate stop in Brasilía, carrying three crew members and a load of various goods such as mail and fish. While descending to São Paulo-Guarulhos Airport in good weather conditions at an altitude of 10,000 feet, the crew encountered technical problems with the trim system. Several manual controls and tests were conducted and the system worked before failing again between 6,000 and 4,700 feet. The captain decided to continue the approach but the aircraft became unstable and nosed down on short final. It landed hard on runway 09R, causing the undercarriage to be torn off. The aircraft slid for about 1,000 metres then veered off runway to the left and came to rest in a grassy area. All three crew members escaped uninjured while the aircraft was damaged beyond repair.

The four engine aircraft departed Paris-Le Bourget Airport on a flight to Valencia, Spain, where members of the chorus of the University of Bénin-Togo were dropped off. At the end of the afternoon, the crew departed Valencia on the final leg of the day to Lomé, Togo. While in cruising altitude over the Niger territory, the crew informed ATC about smoke spreading in the cockpit and was cleared for an emergency descent and landing at Niamey-Diori Hamani Airport. On approach, due to the failure of the hydraulic systems, the crew was unable to lower the undercarriage so a belly landing was completed. The aircraft slid for few dozen metres before coming to rest, bursting into flames. All 10 occupants escaped uninjured while the aircraft was destroyed by fire.

The aircraft was departed Khartoum for a flight to Mwanza where it was supposed to pick up a cargo of 38 tonnes of fish fillet from Vick Fish Processors for delivery in Europe. When it went dark en route to Mwanza, the radio altimeter integral light was found to be unserviceable. The crew were not able to fix the problem and the continued using the FMS. The crew contacted Mwanza tower at 16:58 and were being advised that there was no power at the airport and that efforts were being made to use a standby generator. Further information passed on the crew reportedly included VOR, DME and NDB all unserviceable, weather: wind calm, 8 km visibility, temperature 25deg C and QNH 1015. After holding for 10 minutes, the airport generator came on and the runway lights went on. The first officer, who was pilot flying, started a visual runway 12 approach. When well established on finals with full landing configuration, the captain told the f/o that he was too low, and a few seconds later he told the f/o he was too high. Both the captain and the flight engineer then told the f/o to go around. The f/o overshot and climbed to 5500 feet on the downwind leg. Turning on the left base the captain remarked that the turn was too tight: ".. I will do a 360-degree turn to the right and position you finals". The captain thus took over control and started a right turn at 4400 feet. Just before completing the turn, the f/o said: "do not go down anymore, the altimeter is reading 4100 feet". Almost aligned with the runway, the f/o took over control again. At that same moment the aircraft bounced 2 or 3 times yawing to the left and came down to a halt in the middle of the lake.

Following a wrong approach configuration, the aircraft was too high on the glide and landed too far down the runway. After touchdown, it was unable to stop within the remaining distance, overran and came to rest 150 metres further. All five crew members escaped uninjured while the aircraft was damaged beyond repair. The crew completed the landing procedure with a tailwind component of nine knots.
