The single engine airplane departed Srednekolympsk Airport at 1147LT on a schedule service to Orlovo, carrying 12 passengers and two pilots. Weather conditions were excellent with a visibility of 50 km. About 19 minutes into the flight, weather conditions deteriorated with fog and a visibility below 1,000 meters. Instead of returning to Srednekolympsk, the crew decided to continue and reduced his altitude in an attempt to establish a visual contact with the ground, without success. During 46 minutes, the crew circled in the area of Orlovo to locate the landing field without success and eventually decided to return to Srednekolympsk. On approach of Srednekolympsk Airport, the engine failed. The crew attempted an emergency landing when the aircraft crashed 4 km short of runway. All 14 occupants escaped uninjured while the aircraft was damaged beyond repair.

The four engine aircraft was completing a cargo flight from Tiksi to Irkutsk with an intermediate stop in Batagay, carrying six crew members and a load of 15,5 tons of apples. The descent to Batagay Airport was initiated by night and marginal weather conditions. Thus, the visibility was limited and the crew was unable to establish a visual contact with the ground or the airport. For unknown reasons, the crew and especially the captain failed to follow the approach procedures and preferred to follow a schema dedicated for VFR approach only. This caused the aircraft to descent below the minimum prescribed altitude when the GPWS warning sounded in the cockpit. The captain disengaged the GPWS alarm system and decided to continue the descent when, at a speed of 355 km/h, the aircraft struck the slope of a mountain located 25 km from the Batagay Airport. In a right bank of 22°, the aircraft crashed and disintegrated in a snow covered ground. All six occupants were killed.

After takeoff from Tompo, en route to Topolinoye, the engine emitted a thick white smoke then failed. The crew elected to make an emergency landing when the left main gear collided with rocks on the bank of the Tompo River. Our of control, the aircraft cartwheeled and crashed. All five occupants were rescued, two of them were injured, including the copilot.

The single engine airplane departed Zhigansk at 0506LT on a survey flight over the Dzhardzhan River to identify possible pollution in a water protection program. The mission was conducted over the water at a height of 100 meters, sometime down to 50 meters to inspect boats. En route, the captain asked the copilot to make some calculation for a new route to Sangar. Doing so, the copilot's attention was not focused on the flight and the captain also got distracted, leaving the aircraft descending until it struck the surface of the water. The aircraft crashed and sank. Both pilots and a passenger were able to evacuate the cabin while the second passenger drowned.

Crashed on landing for unknown reason.

The crew (two student pilots and one instructor) was completing a local training flight at Yakutsk-Magan Airport. Ready for takeoff, the crew increased engine power to 85% then released the brakes. After a course of less than 20 meters, the airplane 'sank' on its left after the brakes block of the left main gear broke off. Takeoff procedure was abandoned and the aircraft stopped on its left side and was damaged beyond repair. All three occupants escaped uninjured.

On short final to Innyaly, at a height of one meter, the aircraft 'floated' then rolled to the left, causing the left main gear to struck the ground 150 meters short of runway threshold. The aircraft then rolled for about 250 meters on a wet surface, veered off to the right, went through a wood fence and came to rest with its left gear torn off. There were no casualties but the aircraft was damaged beyond repair.

While approaching the landing area at Lazo, the captain let the copilot conducting the approach but failed to supervise properly his actions. The copilot failed to analyze properly the wind component and on final, the airplane rolled to the right, lost height and crashed. Occupant fate remains unknown. At the time of the accident, the wind was from 150° at 11-21 km/h with gusts at 32 km/h.

During the takeoff roll on the gravel Airstrip at Ust-Maya Airstrip, after passing V1, the left turbocompressor lost power then the engine stopped, 1,8 second before V2 speed. Power on the right engine was increased till 96% and the crew continued the takeoff procedure. Liftoff was completed at a speed of 160 km/h then the aircraft climbed to a height of 50 meters and entered a left turn. Slowly, the altitude dropped and the aircraft eventually crashed in the Aldan River about 270 meters offshore. The wreckage sank and was found 31 hours later. All 14 occupants were killed.

The single engine airplane departed Taymylyr at 1247LT on a special flight to Tiksi, carrying seven passengers, two crew and a load of 192 kilos of various goods on behalf of Yakutsgeofizik. All flight was completed at an altitude of 350 meters and when the crew initiated the descent to Tiksi Airport, he encountered limited visibility due to haze. The aircraft struck the side of a hill (410 meters high) located about 20 km north of the airport, near the Lena River mouth. The aircraft was destroyed and all nine occupants were rescued.
