Circumstances:

En route from Mys-Kamennyy to Vorkuta, weather conditions deteriorated with limited visibility due to low clouds. The crew decided to return to Mys-Kamennyy but this decision was taken too late. At an altitude of 452 metres, while cruising in clouds, the aircraft struck the slope of Mt Konstantinov Kamen (492 metres high). The wreckage was found few hours later. All eight passengers suffered light to moderate injuries while both pilots were killed.

Probable cause:

It was determined that the crew was flying under VFR mode in IMC conditions. At the time of the accident, the cloud base was about 200 metres and the crew lost his orientation and was unable to know his exact position. The wreckage was found about 40 km off the planned route. The accident is the consequence of a controlled flight into terrain.

It struck an earth bank, lost its undercarriage and came to rest in flames. All seven crew members escaped with minor injuries while the aircraft was destroyed by a post crash fire.

Probable cause:

It was determined that the crew failed to follow the pre-takeoff checklist and forgot to position the nosewheel to the neutral position.

Circumstances:

Following a night takeoff from Tarko-Sale Airport, while climbing at a height of 120 meters and a speed of 295 km/h, the captain requested flaps up when the airplane started to descend with a rate of nine meters per second. The aircraft then rolled to the right by an angle of 30° and struck trees at a speed of 365 km/h before crashing 2,889 meters past the runway end. Four crew members and 13 passengers were killed while six other occupants were seriously injured. The aircraft was destroyed.

Probable cause:

The exact cause of the accident could not be determined with certainty. Eyewitnesses reported a red light facing the aircraft just prior to the accident but it was confirmed there was no other traffic in the vicinity of the airport at the time of the accident. It is possible that the red light may be a fire or a possible flare.

Circumstances:

After delivering various equipment for a local oil exploitation company, the crew was returning to Tyumen and departed Mys-Kamennyy Airport at 1911LT in snow showers reducing the visibility to 1,8 km. During initial climb, the crew was cleared to climb to 6,600 meters when four minutes later, the captain declared an emergency and stated that both left engines failed. He was cleared to fly back to Mys-Kamennyy Airport and started a return circuit. At a distance of 18 km from the airfield, he reported runway in sight and lowered the gear shortly later then reduced his altitude to 250 meters at a distance of eight km. At five km, he reported that the aircraft was losing altitude when he was instructed to turn right. Shortly later, at a speed of 220 km/h, the airplane crashed in an icy swamp located 2,2 km short of runway and 450 meters to the left of its extended centerline. The aircraft was destroyed and all eight occupants were killed.

Probable cause:

Investigations were unable to determine the exact cause of the failure of both left engines. Nevertheless, the assumption that this was caused by the presence of ice crystals or pellets clogging a fuel line or a fuel filter was not ruled out as well as a valve failure. Poor weather conditions were considered as a contributing factor.
