Accident
On the night of the accident, a single-engine aircraft departed Pitelino Airfield at 0124 local time for a training flight. While flying at an altitude of approximately 500 to 600 metres, the trim tab on the left aileron deflected fully upward for an unknown reason. This caused the aircraft to bank steeply to the left, enter a downward spiral, and ultimately crash into a rye field located 200 metres from the village of Temirevo, about 4.5 kilometres northeast of Pitelino Airfield.
Crew
The aircraft was carrying three crew members: one instructor and two trainee pilots. All three were killed in the accident.
Cause
The official investigation determined the probable cause of the accident to be an aileron failure.
