Circumstances:
While cruising at an altitude of 1,300 meters in poor weather conditions, the crew started the descent to Kirensk despite the fact that he was unaware of his real position. While descending into clouds, the aircraft hit the slope of a mountain located 117 km east of Kirensk. The wreckage was found few hours later and ten survivors (three crew members and seven passengers) were evacuated while 14 other occupants were killed.
Probable cause:
It appears that the aircraft was off track by 70 km to the southeast at the time of the accident due to a navigational error on part of the crew. It was reported that this navigational error was caused by poor piloting methods on part of the crew who decided to start the descent to Kirensk without knowing his exact position. The lack of visibility due to clouds was considered as a contributory factor.

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.

Circumstances:
The airplane departed Irkutsk Airport to transfer a patient to Nizhne-Ilimsk with intermediate stops in Balagansk, Zhigalovo and Ust-Kut. After passing a night at Balagansk, the pilot continued on December 26 to Zhigalovo. As the airplane failed to arrive at destination, SAR operations were initiated but eventually abandoned after few days as no trace of the aircraft nor the three occupants was found. It is believed that the pilot encountered poor visibility due to fog while approaching Zhigalovo, missed the airfield and probably deviated by approximately 150 km in the area of the Kirenga River. Eventually, the airplane may have crashed due to fuel exhaustion. The wreckage was never found.

Circumstances:
The airplane departed Irkutsk on a flight to Yakutsk with intermediate stops in Balagansk and Ust-Kut, carrying three passengers, two crew members, 240 kg of bagages and 727 kg of mail. Approaching Ust-Kut, the engine lost power and started vibrating. The pilot shut it down and attempted an emergency landing when the airplane clipped trees and crashed in a wooded area located 50 km south of Ust-Kut. The captain was killed while four other occupants were injured. The following day, they walked through the taïga and found rescue.
Probable cause:
It was determined that the engine failed in flight due to a fuel issue that was caused either by:
- the fuel valve was closed;
- a foreign object obstructed the fuel line;
_ the fuel pump failed.

Both aircraft entered a dive and crashed near the airport. Both pilots were killed.
Probable cause:
Lack of discipline on the part of the pilot of CCCP-T118 who changed his heading and flew out of his designated area, violating instructions and published procedures.

Circumstances:
The pilot, sole on board, departed Irkutsk at 1440LT on a mail flight to Krasnoyarsk. After passing over Nizhneudinsk, he encountered poor weather conditions with blizzard and heavy snow falls. He reduced his altitude to establish a visual contact with the ground and elected to return to Nizhneudinsk. At a height of about 20 metres, the airplane impacted the top of a larch tree with its right wing, continued for about 50 metres then crashed in a wooded area, bursting into flames. The pilot was killed.
Probable cause:
The accident resulted from an impact with trees while cruising at low altitude through poor visibility due to bad weather conditions. It was determined that the pilot was cleared to takeoff from Irkutsk despite the weather conditions en route were unfavorable. Also, the pilot was inexperienced in instrument flights.

Circumstances:
The floatplane was engaged in a schedule service from Irkutsk to Bodaibo, carrying four passengers and a crew of three. On the Angara River, the captain travelled a distance of about 100 metres then made a 180 turn to start the takeoff procedure. At this time, the distance between the airplane and the first building in the city was about 1300-1400 metres. At a distance of 30-35 metres from the shore, the pilot started the rotation and the airplane took off despite its speed was insufficient. It climbed in a nose up attitude then collided with a two-story house, causing the empennage to be torn off. The airplane stalled and crashed in the Transportnaya street. A passenger was seriously injured while six other occupants were killed.
Probable cause:
The pilot decided to takeoff facing the city from a distance that was obviously insufficient. He also initiated the rotation while the aircraft' speed was too low.

Circumstances:
The airplane departed Irkutsk on a cargo flight to Bodaibo, carrying four passengers and a crew of three. While cruising some 40 km from Kirensk, weather conditions worsened and the visibility was poor due to heavy snow falls. The captain reduced his altitude, apparently to maintain a visual contact with the ground. At a height of about 20-30 metres, the airplane went out of control and crashed in the Lena River near the village of Kulebyakino, some 15 km southwest of Kirensk. Two passengers were injured while five other occupants were killed.
Probable cause:
The exact cause of the accident could not be determined. However, the pilot was inexperienced on this type of aircraft (this was his third flight on type) and there were four passengers on board while this aircraft was not certified to accept passengers.
