The plane involved in the accident was a Boeing 707-3F9C built in 1972 , which was registered with Nigeria Airways with the aircraft registration 5N-ABK . The machine had completed 31,477 flight hours up to the accident.
Crew and passengers
The captain had 10,917 hours of flying experience, of which 3594.5 on the Boeing 707. The first officer had type ratings for the Boeing 707 and the Boeing 727 and 5,201 hours of flight experience, he which had graduated in 2000 on the Boeing 707th The flight engineer had 2,293 hours of flight experience. At the time of the accident, kerosene was still in the tanks for 2.5 hours of flight. The machine had loaded about 35 tons of cargo. The loadmaster and a mechanic were on board as passengers, both of whom later died in the accident.
Flight history
The machine was supposed to fly 13 empty freight pallets from Kano to Jeddah on December 18, 1994 and bring them back loaded. The flight was almost canceled by the captain at first, as only five pallets were loaded and the employee who managed the keys for the pallet warehouse did not show up for work that day. Finally, an agreement was reached on site so that seven more pallets were loaded for departure. The plane took off from Kano at 5 p.m. UTC and landed in Jeddah a few minutes after 10 p.m. UTC. The calculated handling time up to the return flight should have been an hour and a half as planned, but it finally took an hour longer for the pallets to be loaded in Jeddah. At 0:30 UTC the machine was ready to take off, but engine no. 4 failed while the engines were being started, so that the machine remained at the airport overnight. After the repair, the machine took off from Jeddah at 13:48 UTC and was scheduled to arrive at Kano at 18:19 UTC. The master had not been warned that any dangerous goods were being loaded. When the aircraft flew over N'Djamena at around 5:00 p.m. UTC at an altitude of 35,000 feet , the flight engineer noticed a strange smell in the cockpit. The inmates noticed that the odor did not seem to go away. The two passengers in the hold tried to follow the path of the odor development and finally became aware of pallet no. 11, which appeared to be emitting a kind of fog. The men sprayed the pallet with a fire extinguisher. After the subsequent activation of the smoke extraction system, the occupants of the machine were initially unable to detect any further smoke or odor formation. At 6 p.m. UTC, the crew received clearance to sink for the approach to Kano. Shortly afterwards, a warning signal sounded, a minute later a fire warning was triggered and smoke began to move into the cockpit. The pilots then initiated a rapid descent of 3,000 feet (910 meters) per minute. The flight engineer made radio contact with the airline at 18:04, but this was broken off seven seconds later and thus at the same time as the recordings on the voice recorder. At that moment there had been an explosion in the cargo hold that disabled the autopilot. Shortly thereafter, there was a second explosion that rocked the plane violently. The machine slowly sank into a swamp near Kiri Kasana, but rolled after the first contact with water. Three of the five people on board were killed, including the two men who had been sitting in the loading area.
Cause of accident
It could be determined that the aircraft had loaded an undeclared, highly reactive, heat-generating substance. The smoke moving into the cockpit impaired the crew's ability to act, and the fire and the two explosions also had a massive impact on the machine's control systems.
