Circumstances:
The takeoff was attempted from a dirt runway with puddles.

The airplane went off runway then took off after a course of 945 meters. During initial climb, after a course of 200 meters and at an altitude of 14 meters, the airplane struck trees, stalled and crashed in flames in a wooded area. A passenger was injured while 39 other occupants were killed. The aircraft was destroyed by a post crash fire.
Probable cause:
The crew attempted to takeoff from an impassable runway with a tailwind component.

Circumstances:
From May 28 till May 31, the airplane was dispatched in Kalinovskaya for spraying missions on behalf of the Lenin's kolkhoz. While parked, a technician decided to takeoff and to make a local tour. Shortly after takeoff, while flying at a height of 500 meters, he lost control of the airplane that descended by at an angle of 60° and crashed in flames in an open field. The sole occupant was killed.
Probable cause:
The technician was not intoxicated and the assumption that the accident was the consequence of suicide was not ruled out.

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.

At an estimated altitude of 175 meters, the airplane collided with an Aeroflot PZL-Mielec AN-2TP registered CCCP-44992 that was completing a service from Tavda to Tyumen and just departed Tavda Airport few minutes earlier with 14 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.

Circumstances:
The airplane departed Ayanka Airstrip at 1332LT on a flight to Tilichiki, carrying one passenger, three crew members and a load of 10 empty fuel barrels. Sixteen minutes later, while cruising at an altitude of 1,800 meters in good weather conditions, the pilot informed ATC about a strong smell of fuel on board and elected to return to Ayanka. Six minutes later, engine fuel pressure dropped while the fuel smell was still present. A minute and 35 seconds later, the engine caught fire. The crew reduced his altitude and attempted an emergency landing when, at an altitude of 400 meters, the airplane nosed down and crashed by an angle of 60° in a small icy lake located 20 km southeast of Ayanka. The aircraft was destroyed and all four occupants were killed.
Probable cause:
A fuel leak whose origin remains unknown occurred in flight and the pilots' decision to return to Ayanka was correct. However, the intensity of the engine fire did not allow the crew to complete an emergency landing.

Circumstances:
The crew was engaged in a training flight out from Novosibirsk-Severny Airport. En route, while in cruising altitude, the crew simulated a failure of the left engine and gave maximum right rudder, leading to an aerodynamic overbalancing and resulting to a side-slip (it was impossible to return the rudder to the neutral position in this situation). The aircraft went out of control, entered a dive and crashed in a snow-covered swampy bush land located near the village of Penyok, some 91 km of the Novosibirsk-Tolmachevo Airport. All six crew members were killed.

Circumstances:
A group of seven PZL-Mielec AN-2 must be transferred from Urgench, Uzbekistan, to Myashkovo, with intermediate stops in Uralsk and Penza, carrying mechanics and crew members. En route from Uralsk to Penza, while cruising at an altitude of 500 meters, both aircraft registered CCCP-28938 and CCCP-32112 entered a cloudy area with light rain. They collided then entered a dive and crashed in flames 350 meters further, 25 meters from each other. Both aircraft were totally destroyed and all 10 occupants were killed.
Probable cause:
Poor flight preparation and planning as all crew and the people in charge of the mission failed to analyze weather conditions en route. The collision occurred while both crew were flying under VFR mode in adverse weather conditions.
