Kenkiyak | Bureau of Aircraft Accidents Archives

The crew continued the approach with an excessive rate of descent and at too high speed. Upon touchdown, the aircraft bounced three times then landed on its nose gear that collapsed. The aircraft slid for few dozen meters then overran and came to rest 83 meters past the runway end, bursting into flames. All 33 occupants were evacuated safely while the aircraft was destroyed.

Probable cause:

Wrong approach configuration on part of the crew who completed an approach and landing in a nose-down attitude with excessive speed and rate of descent. It was also determined that the braking systems were partially inoperative due to hydraulic failure, which was considered as a contributing factor.

Circumstances:

The airplane was engaged in a flight from Aktyubinsk to Kenkiyak, carrying 12 passengers and a crew of two on behalf of an oil exploration company. Rotation was completed at a speed of 80 km/h after a course of 180 meters. During initial climb, at a height of 5-7 meters, at a speed of 120 km/h, the airplane banked left then lost height and crashed 210 meters from the runway end, rolled for about 26 meters and came to rest. Two passengers were killed while 12 other occupants were seriously injured.

Probable cause:

It was determined that the loss of control during initial climb was the consequence of a weight & balance problem. Investigations revealed that the aircraft was generally used for support and other missions in the past and was flying with passengers for the first time. By a local manufacturing plant, several equipment such as radios and batteries were moved to the rear of the cabin, modifying the center of gravity that was out of the envelope, too far aft (4%). For unknown reasons, the aircraft technical documents were not modified accordingly and the crew was not aware of these modifications.

Circumstances:

On the leg from Baiganin to Kenkiyak of a flight from Baiganin to Aktyubinsk, the crew encountered below-minima weather conditions (low clouds and fog), but failed to return to Baiganin and descended instead so that the aircraft crashed at a height of 273 metres into a hill (288 metres) located 18 km southwest of Kenkiyak. The copilot and two passengers were killed. The captain was seriously injured and all other passengers were slightly injured. The aircraft was destroyed.

Probable cause:

It was determined that the crew decided to continue the descent to Kenkiyak in below-minima weather conditions instead of returning to Baiganin. Informations related to weather conditions and transmitted to the crew did not reflect the truth and were considered as too optimistic, which was considered as a contributing factor.
