Circumstances:
After departure from Mariinskoye Airport bound for Khabarovsk, while cruising at an altitude of 1,350 meters, weather conditions worsened. The crew reduced his altitude to 750 meters and decided to modify his route bound for Troitskoye. While cruising in clouds, the airplane crashed on the slope of a mountain located 22 km southeast of Selikhino. As the aircraft failed to arrive at destination, SAR operations were initiated and the burnt wreckage was found a day later at an altitude of 630 meters. A boy aged 13 was injured while 10 other occupants were killed.
Probable cause:
The decision of the crew to continue in adverse weather conditions (low clouds and rain falls) below the minimum safe altitude prescribed for the area. The lack of ATC assistance was considered as a contributing factor.

During the last segment, the pilot-in-command abruptly reduced the engine power, causing the aircraft to lose altitude and to struck the runway surface. The aircraft then rolled for few dozen meters before coming to rest. All occupants escaped uninjured while the aircraft was considered as damaged beyond repair.
Probable cause:
An excessive reduction of the engine power on final caused the aircraft to lose altitude and to roughly struck the runway surface. The following contributing factors were reported:
- Insufficient approach speed,
- Confusion by the flying crew,
- Incorrect compensation of the wind component,
- Limited runway length.

Circumstances:
The airplane departed Susuman Airfield at 0826LT on a prospecting mission on behalf of the 22nd Geophysical NPN Group based in Seymchan. It was carrying three crew members and three operators of the NPN Group. While cruising in a valley at an altitude of 800 meters, the airplane struck power cables (it cut three cables), went out of control and crashed in flames 375 meters further. All three crew members were seriously injured and all three passengers were killed.
Probable cause:
It was determined that the crew failed to follow the minimum prescribed altitude during the mission and failed to see and avoid the cables that were located about 50 meters above the ground. A poor flight planning and the fact that the mission was not well organized by the geophysical company were considered as contributing factors.

The single engine airplane departed Tavda Airport on flight SU801CH to Tyumen, carrying 12 passengers and two pilots on board. After takeoff, the crew was cleared to climb to an altitude of 150 meters and continued to the south. Few minutes later, while cruising in marginal weather conditions with rain falls, limited visibility of 2 km and low clouds, at an estimated altitude of 175 meters, the airplane collided with an Aeroflot Antonov AN-2 registered CCCP-15925 that was completing a service from Tyumen to Tavda with 15 people on board. Following the collision, both aircraft went out of control, entered a dive and crashed in flames in an open field located 18 km south of Tavda. Both wreckages were found 392 meters from each other and all 29 occupants on both aircraft were killed.
Probable cause:
The in-flight collision was the consequence of a lack of ATC assistance and the fact that both crew were flying under VFR mode in adverse weather conditions.
