Circumstances:
The single engine airplane departed Bodaibo under VFR mode on a charter flight to Valyukhta with intermediate stops in Svetly and Perevoz. En route, weather conditions deteriorated with low clouds. At an altitude of 1,520 metres, the aircraft struck the slope of a mountain and crashed, bursting into flames. All five occupants escaped with minor injuries while the aircraft was destroyed by fire. The wreckage was found 68 km northeast of Bodaibo.
Probable cause:
Controlled flight into terrain after the crew decided to continue under VFR mode in IMC conditions. Poor operation planning by the operator and poor visibility due to the presence of cumulonimbus were considered as contributing factors.

Circumstances:
The crew was performing a cargo flight from Irkutsk to Bodaibo with an intermediate stop in Kirensk, carrying a load of apples and mail for a total of 2,222 kilos. One hour and 13 minutes after his departure from Kirensk, the crew encountered technical problems with both engines that lost power. The captain elected to make an emergency landing when the aircraft hit tree tops and crashed in flames in a wooded area located 25 km from Parshino. The aircraft was destroyed by impact forces and a post crash fire and all four crew members were killed.
Probable cause:
It was determined that both engines failed because the carburetor was not properly supplied by fuel that was contaminated by water (up to 16%) that partially iced in the tanks and the fuel supply systems. Investigations revealed that the fuel supply, transportation and storage procedures at Kirensk were not followed properly by the authorities. Fuel tanks were stored in full sun and were not waterproof, allowing condensation to form and contaminate the fuel that have not been drained.

Circumstances:
Approaching Bodaibo, the crew lost his orientation due to low visibility caused by poor weather conditions (snow falls). The captain decided to reduce his altitude and followed the Vitim River to join Bodaibo Airport at a height of 100 meters. The aircraft hit the water surface and crashed in a huge explosion into the river off Mamakan, about 13 km southwest of Bodaibo. A passenger was injured and rescued while all 28 other occupants were killed.
Probable cause:
The accident occurred in flight conditions that were below published minima. It was reported that the weather prediction were not efficient and did not reflect the truth. The pilot took the wrong decision to continue and to descent in such poor weather conditions.
