Circumstances:
The crew was performing a cargo flight from Leningrad to Saratov with an intermediate stop at Penza, carrying a load of refrigerator spare parts. After takeoff from Penza Airport, while climbing by night, the airplane banked left to 40° then stalled and crashed in flames in a field located 2 km from the airport. The aircraft was destroyed by impact forces and a post crash fire and all five crew members were killed.
Probable cause:
It was determined that the loss of control during initial climb was caused by an excessive accumulation of ice on both engines and propeller blades. Due to a poor flight preparation and a wrong interpretation of the weather conditions, the captain decided to takeoff in freezing rain. The assumption that all speed indicators, altimeters and variometers were unserviceable at the time of the accident was not ruled out. Also, both engines did not run at impact.

Circumstances:
The crew was flying at an altitude of 1,500 meters in VFR mode above the clouds when he received the permission by ATC to descent to 400 meters. While cruising in cloudy conditions at the altitude of 950 meters, the airplane hit tree tops, nosed down and crashed in flames in a wooded area located in Privetnoye. The wreckage was spotted on the slope of Mt Kharpuzyany Kayas and all 12 occupants have been killed.
Probable cause:
The accident was the consequence of ATC errors who failed to monitor the flight properly in reference to approach procedures, and allowed the crew to descent to an insufficient altitude. First, the crew was granted to fly at an altitude of 1,500 meters instead of the minimum 2,100 meters requested. Secondly, the ATC allowed the crew to descend to 400 meters although he knew the aircraft was flying in clouds and above a mountainous area.

From an altitude of 900 meters, the crew started a steep descent and completed an emergency landing at Jõhvi Airport. All crew members and passengers were able to evacuate the cabin and were uninjured while the hijacker was killed when the airplane was destroyed by fire.
Probable cause:
Hijacked and set on fire.
