Baku-Heydar Aliyev (Bina) | Bureau of Aircraft Accidents Archives

While cruising at an altitude of 9,600 meters on a flight from Baku to Leningrad, all three engines stopped simultaneously. Shortly later, all generators failed as well, causing the electrical system to be inoperative. Unable to maintain altitude and speed that dropped to 370 km/h, the crew attempted an emergency landing in an open field. After touchdown, the airplane slid for 1,518 meters, struck various obstacles and came to rest in flames. Four passengers were killed while 130 other occupants were rescued, some of them were injured. The aircraft was destroyed.

Probable cause:

In-flight failure of all three engines after the fuel transfer system failed while being connected on manual mode. Technical analysis were unable to determine the exact cause of the fuel transfer system failure but it is possible this was caused by the malfunction or the failure of a switch or other electrical components.

Circumstances:

Following a normal takeoff roll, the crew started the rotation at a speed of 220 km/h. Five second after liftoff, while climbing to a height of 10 meters, the left engine failed. The left propeller was automatically feathered and the crew continued to climb. 34 seconds after takeoff, the airplane was at an altitude of 30 meters at a speed of 230 km/h when the crew retracted the flaps. Six seconds later, at a height of 40 meters and a speed of 227 km/h, the pilot-in-command initiated a left turn when the airplane drifted to the left. It lost speed then stalled and crashed in flames on a pipeline owned by the Neftyanyye Kamni Oil Company. Two crew members and 54 passengers were killed while eight other occupants were injured.

Probable cause:

It was determined that several blades on the first stage of the turbine have disintegrated due to a reduction of their mechanical properties due to a previous overheating, probably beyond 1,150°. Nevertheless, it was not possible to establish the exact cause of the overheating of the blades and to define the period when this occurred.

Circumstances:

The airplane departed Baku-Bina Airport at 1245LT on a special flight to Tbilisi. On board were five crew members and a technician from the Air Force. About 15 minutes into the flight, while cruising at an altitude of 800 metres in clouds, the airplane hit the slope of a mountain (900 metres high) located near the city of Shamakhi, just above the Dzheirankechmaz River. The passenger and the copilot were injured while four other crew members were killed. The copilot died the following day from injuries sustained.

Probable cause:

The accident was caused by the pilot's failure to follow a safe flight path. The flight took place over mountainous, cloud-covered terrain, instead of over flat ground where the cloud height would have allowed a visual flight. What's more, the route chosen by the pilot was not foreseen in the weather forecast he had been given. Controlled flight into terrain.
