Circumstances:
The single engine airplane departed Buguruslan Airport at 1332LT on a local training flight, carrying one pilot, one instructor and two cadets. Weather conditions were marginal due to snow falls. After several circuits were completed at an altitude of 700 meters, the crew informed ATC he was descending to 300 meters when control was lost. The airplane lost altitude and crashed in an open field located in Ponikla, bursting into flames. The aircraft was destroyed and all four occupants were killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, it was reported that the engine failed en route after it got cold while operated in very low OAT. The lack of crew experience and skills in winter conditions was considered as a contributing factor.

Circumstances:
The crew, consisting of one instructor and three pilots, was completing a local training flight in Buguruslan-Baymakovo Airport. A first training program was completed at an altitude of 1,000 meters and the instructor ordered the crew to return to the airport. On final approach, during the last segment, the instructor ordered the crew to go around and increased power on both engines. During the initial climb, while at a height of 150 meters, the instructor shut down the right engine and feathered its propeller. At the same time, the aircraft banked left up to 30°, stalled, dove into the ground and crashed in a huge explosion. The aircraft was destroyed by impact forces and a post crash fire and all four crew members were killed.
Probable cause:
It was determined that the aircraft stalled during initial climb due to the combination of flaps deployed at an angle of 17° and the power reduction on the right engine. Unfortunately, the distance between the aircraft and the ground was insufficient to a expect any recovery. The instructor decided to make a single engine climb out in violation of the NPP-47 training program and instructions published for IL-12. Wrong interpretation of the situation on part of the rest of the crew also contributed to the loss of control. The following factors were considered as contributory:
- Absence of appropriate measures concerning pilots management and training,
- Lack of control and demands in relation to the flight crews.
