On approach to Nizhneangarsk Airport, the crew encountered low clouds. The visibility was limited and the crew lost visual contact with ground. While at an altitude of 150 metres, the airplane struck tree tops and crashed in flames in a wooded area located 4 km short of runway. The aircraft was destroyed by a post crash fire and while two passengers were seriously injured, all five other occupants were killed.

Probable cause:

The accident was the consequence of the crew’s violation of the rules for flight operations in accordance with the published procedures established by ULP. Weather and ATC were not considered as contributing factors.

Circumstances:

The airplane was engaged in a special mission on behalf of the Voyekova Geophysical Observatory, carrying a crew of five and six passengers, among them three employees of the observatory. Following a successfully mission consisting of thunderstorm observation, the crew was approaching Bagdarin when he encountered poor weather conditions with low clouds and heavy rain falls. While descending to an altitude of 600 meters in clouds, the airplane struck tree tops, stalled and crashed in flames in a wooded area located on the slope of a mountain (827 meters high), about 28 km from the Bagdarin Airport. The aircraft was totally destroyed and all 11 occupants have been killed.

Probable cause:

Poor approach planning on part of the crew who failed to follow the approved procedures and adopted a wrong approach configuration, causing the aircraft to descend to an unsafe altitude over mountainous area and in poor weather conditions. The lack of visibility due to clouds and rain was considered as a contributing factor as well as a poor ATC assistance.

Circumstances:

During an unauthorized flight from Shiringa (Sosnovo-Ozyorskoye district of Buryatia) while on crop-spraying operations for the sovkhoz (state farm) of "Yeravninski", at an altitude of some 100-200 meters, the airplane banked left then lost height and crashed 6 km from Shiringa. Both pilots and both passengers were killed.

Probable cause:

The cause of the accident could not be determined but the assumption that the engine failed was not ruled out.

Circumstances:

The crew departed Ulan-Ude-Mukhino Airport on a local training flight. Following several circuits, it was decided to shut down an engine to simulate a failure. After the propeller was feathered, the flight engineer mistakenly shut down the second engine. The crew completed a belly landing on the Bodorodski Island located about 8 km short of runway 26. The aircraft was partially consumed by a post crash fire and all crew members were slightly injured.

Probable cause:

Engine mistakenly shot down by the flight engineer during a single engine exercise.

Circumstances:

The aircraft departed Tashkent on a cargo flight to Yuzhno-Sakhalinsk with intermediate stops in Fergana, Novosibirsk, Krasnoyarsk and Irkutsk, carrying a load of 10,475 kilos of grapes. En route from Krasnoyarsk to Irkutsk, the crew was informed about poor weather at destination and decided to divert to Ulan Ude although that airport was not suitable for such type of aircraft. While approaching from the north in marginal weather conditions, at an altitude of 1,200 meters, the airplane struck the slope of a wooded mountain located 32 km north of the airfield. The aircraft was destroyed and all eight occupants were killed.

Probable cause:

Controlled flight into terrain resulting from a crew error who mistakenly imputed wrong QNH setting for the approach. Lack of visibility and poor flight preparation were considered as contributing factors.

Circumstances:

The crew departed Nizhneangarsk Airport at 0843LT on a cargo flight to Dovyren and Irkana, carrying a load of six diesel drums. Twelve minutes later, the crew reported he was climbing to an altitude of 1,200 meters in good weather conditions. About ten minutes later, the single engine airplane crashed in a mountainous area located 7-10 km from Dovyren. As the aircraft failed to arrive at Dovyren, SAR oeprations were conducted and the wreckage was found a day later. Both crew members were killed.

Probable cause:

It was determined that one of the propeller blades failed in flight and struck and broke the windshield. In low visibility caused by snow falls, the crew was unable to attempt an emergency landing as he was flying over a mountainous area. The failure of the propeller blade was caused by a faulty manufacture.

Circumstances:

For unknown reason, the crew hurried the departure from Bagdarin to Romanovka. The aircraft was carrying eight passengers, two pilots, 300 kilos of cargo and 68 kg of mail. The captain asked the copilot to precipitate the takeoff procedure. So as soon as all eight passengers boarded, the crew started the engine, completed the taxi and joined the runway. After a takeoff run of 110 meters, the copilot started the rotation. The aircraft climbed to a height of one meter, continued for about 30 meters and banked left, hit the ground and crashed. Both pilots and one passenger were killed while seven other occupants were injured. The aircraft was destroyed.

Probable cause:

For unknown reason, the captain decided to hurry the departure from Bagdarin Airport. Thus, he failed to follow the pre-departure checklist and started the engine and the taxi procedure without making a visual check of the airplane. Investigations determined that the loss of control that occurred after rotation was the consequence of an error on part of the crew who failed to remove a chock that was blocking the ailerons on ground.

Circumstances:

On the left from Irkutsk to Chita, while cruising by night at an assigned altitude of 3,000 meters, the crew encountered icing conditions and received the permission to reduce his altitude to 2,400 meters. Few minutes later, at 0512LT, the crew contacted ATC but was asked to standby because the frequency and the ATC was busy. Two minutes later, while an altitude of 1,400 meters, the aircraft hit tree tops and crashed 150 meters further in a wooded area located on the slope of the Kabanya Mountain (1,479 meters high). The aircraft was destroyed by impact forces and a post crash fire and all 14 occupants were killed, among them probably some members of the self-proclaimed government of the East Turkestan Republic.

Probable cause:

No technical issue or findings were found with the aircraft or its equipment, instruments or components. Investigations were unable to determine the reason why the crew was flying at the altitude of 1,400 meters, below the assigned flight level. In such conditions, it was considered that the accident was caused by a controlled flight into terrain.

En route, the engine caught fire an the pilot attempted an emergency landing when the airplane crashed on the ice of Lake Baïkal, some 10 km west of Posolskoye. SAR operations were initiated three days later only. The aircraft was totally destroyed by a post crash fire and both occupants were not found. Some foot print were found on ice and snow but both occupants were later considered as deceased.

Probable cause:

Engine fire in flight, maybe following the failure of a fuel supply or a malfunction of the carburetor.
