Probable cause:
It was determined that the artificial horizon failed after takeoff. While climbing into clouds, the pilot-in-command suffered a spatial disorientation and lost control of the airplane.

Circumstances:
While parked at Tolmachevo Airport with negative temperatures, ground employees in charge to clean the cabin installed a heater on a vehicle to heat the cabin. The aircraft engineer who performed the work left the operating heater unattended and left. At the same time, an oily rag was forgotten in front of the inlet of the air heater, which was subsequently drawn into the air heater, caught fire and was thrown through the sleeve into the aircraft cabin. The fire was not detected rapidly so it spread in the cabin and destroyed a large part of the aircraft. There were no injuries.

Circumstances:
The single engine airplane departed Yaroslavl Airport at 1032LT on a cargo flight to Pechora with several enroute stops. After passing over Vologda (without landing), while at an altitude of 125 meters, the airplane collided with another PZL-Mielec AN-2TP registered CCCP-40563 that just took off from Vologda on a flight to Babushkina with six passengers and a crew of two on board. Following the collision, the first AN-2 went out of control and crashed in a field while the crew of the second aircraft was able to perform an emergency landing. All eight occupants escaped uninjured while both pilots in the first airplane were killed.
Probable cause:
Failure of the crew to adhere to navigation and communication procedures with ATC. It was also determined that the total weight of the aircraft was 150 kilos above MTOW from Yaroslavl Airport, which was considered as a contributing factor as this reduced the aircraft's speed that arrived too late over Vologda referring to the estimated time of arrival.

Circumstances:
The AN-12PPS left Šiauliai in the evening on a training exercise over the Pskov oblast. In the meantime left a Sukhoi SU-15 from the Khotilovo Airbase (Tver region) to simulate the aerial attack of another Antonov AN-12PPS flying in the same region as the first one. The exercise started in good weather conditions but in low visibility due to the night. Radio transmissions between different crews were difficult due to interferences. When the jet fighter pilot completed the mission, he attempted a last turn when he collided with the first AN-12. Both aircraft dove into the ground and crashed in a field, killing all nine occupants on both aircraft.
Probable cause:
The fighter pilot has not been informed of the presence of the first AN-12PPS in the region of the exercise, most probably due to negligence in the preparation of the mission or due to poor coordination between all crew engaged in the mission. It is also possible that the presence of interferences on radio frequencies has hampered the progress of the exercise.

Circumstances:
Following a night takeoff from Tarko-Sale Airport, while climbing at a height of 120 meters and a speed of 295 km/h, the captain requested flaps up when the airplane started to descend with a rate of nine meters per second. The aircraft then rolled to the right by an angle of 30° and struck trees at a speed of 365 km/h before crashing 2,889 meters past the runway end. Four crew members and 13 passengers were killed while six other occupants were seriously injured. The aircraft was destroyed.
Probable cause:
The exact cause of the accident could not be determined with certainty. Eyewitnesses reported a red light facing the aircraft just prior to the accident but it was confirmed there was no other traffic in the vicinity of the airport at the time of the accident. It is possible that the red light may be a fire or a possible flare.
