Accident Details
On the day of the accident, the crew was completing a local training mission at Tomsk-Bogashovo Airport. After performing four circuits, the pilot-in-command initiated a left turn at a height of approximately 120 meters. During the turn, the airplane banked left to an angle of 20°, then stalled and crashed 230 meters from the southern runway threshold. The aircraft was totally destroyed by impact forces and a post-crash fire. All three crew members were killed.
