Circumstances:
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.

Circumstances:
The single engine airplane departed Ust-Kulom Airport at 1228LT bound for Syktyvkar with seven passengers and a crew of two on board, accompanied by a second Aeroflot AN-2 (CCCP-98382) that left at the same time. En route, weather conditions worsened and both crew lost visual contact with each other. Approaching Syktyvkar, the crew was informed about the deterioration of the weather with a limited visibility of 1,500 - 2,500 meters in snow. Few radios communications issues occurred and while descending at a height of 150 meters and making a right turn, the pilot saw the second AN-2 and made a sharp turn to avoid collision when control was lost. The airplane crashed on the icy Vychegda River, about 13 km from the Syktyvkar main Station. While the aircraft was destroyed, all nine occupants were injured. About four days later, one of the passengers died from his injuries.
Probable cause:
The main cause of the accident was the dangerous convergence of the aircraft due to the extremely irresponsible attitude of the management and dispatching personnel of the Syktyvkar ATC service to fulfill published procedures related to the organization and the control of the aircraft in deteriorated weather conditions.

It stalled and crashed by an angle of 70°. The aircraft was destroyed and both pilots were killed.
Probable cause:
The crew completed hazardous manoeuvres at low height, causing the aircraft to be uncontrollable. While the copilot was slightly intoxicated, the captain had not consumed alcohol.

Circumstances:
In the morning, the crew completed two flights in the area. Due to engine problems, a technician was asked to make some engine test run. While the aircraft was parked on the ground, a technician proceeded to an engine test but forgot to install chocks on wheels. After the engine was started, power was added. The pilot who was standing by the door fell out of the plane that started to roll. After takeoff, the airplane climbed to a height of 12 meters, made a sharp turn to the left, stalled and crashed upside down. The technician, sole on board, was killed. It was determined that when the airplane started to roll quite roughly, the technician fell down from the pilot seat. Then, after liftoff, the cargo shifted to the rear of the cabin, causing the aircraft to stall.
Probable cause:
The technician in charge to proceed to an engine test started the engine and added full power without preparing the airplane properly and installing chocks on wheels prior to the test. The aircraft then moved roughly and became uncontrollable.
