What happened
During a flight originating from Novokuznetsk toward destinations including Gorno-Altaysk and Aktash, a single-engine aircraft experienced significant difficulties maintaining altitude following takeoff. The aircraft, which was transporting a small group of geologists, struck trees during its climb before entering a stall and ultimately crashing. At the time of the incident, the departure took place from an elevation of 1,470 meters under high temperature conditions of +30° C. The status of the occupant remains unconfirmed.
Findings
Investigations into the accident identified several critical factors that contributed to the loss of control. The aircraft was operating at a weight that exceeded its maximum takeoff weight by 358 kilos. This excessive loading, combined with an insufficient takeoff speed, prevented the plane from climbing effectively. Additionally, environmental factors played a role, specifically the high ambient temperature and the resulting effects of altitude density on performance.
