From November 1, 1985, the machine was leased to Southern Air , which operated it for Burlington Air Express . During this time the machine was provided with two completely different liveries of the Burlington Air Express one after the other. Buffalo Airways bought the machine in January 1992 . She leased them from June 23, 1993 to Air UK and from October 10, 1993 to AZAL Avia Cargo , a subsidiary of Azerbaijan Airlines that operates cargo flights.

Crew and flight plan

The machine was used to fly an international cargo flight from Urumqi-Diwopu Airport in the People's Republic of China to Baku Airport in Azerbaijan . There was a crew of six on board.

the accident

After starting the machine in Ürümqi , the landing gear could no longer be retracted. Instead of turning back and having the defect repaired, the crew decided to fly the plane to the destination Baku airport. Due to the extended landing gear, however, the aircraft consumed considerable kerosene on the flight. The crew managed to get into the airspace of Azerbaijan with the machine, but there was very little kerosene in the tanks on the approach to Baku. The pilots initially made a false approach , they flew over the runway in Baku at a low altitude and then flew a right turn in order to align the machine again for a final approach. Shortly afterwards, the engines failed due to a lack of fuel. The machine lost height, brushed against the posts of a road bridge and fell into a field 9 kilometers from the airport. Two crew members were killed.

causes

The accident investigation identified several factors that contributed to the accident. Due to a malfunction of the retraction mechanism for the landing gear, it remained extended, which had led to considerable kerosene consumption. In addition, on the approach to Baku, the crew was initially unable to lock the left main landing gear in the extended position, which is why a missed approach had to be carried out with low fuel reserves. The fuel displays were also imprecise, which is why the crew did not have correct information on the fuel supplies and therefore did not look up the manufacturer's recommendations for flights with little fuel in the manual. Furthermore, there was no notification from the airline regarding the properties of the Boeing 707's fuel system, so the crew was unable to identify and apply the optimal operating mode for low-fuel flights. Finally, the companies concerned, Baku Air and ALG Inc., criticized the inadequate company policy with regard to operation and maintenance.
