What happened
The incident occurred during a scheduled cargo flight bound for Kuybyshev. The aircraft was transporting a mixed load of goods, specifically studs, cord, and gloves. Shortly after lifting off from the runway, the plane began its initial climb. At an altitude of approximately 40 meters, the airframe entered an aerodynamic stall. Following this loss of lift, the aircraft banked to the right and descended rapidly. It impacted the ground roughly 200 meters beyond the perimeter fence, resulting in a massive explosion. All six occupants aboard were killed in the crash.
Findings
The official investigation concluded that the accident resulted from inadequate pre-flight preparation. The crew failed to adhere to the required pre-departure checklist procedures. Specifically, they did not verify the position of the elevator trim tabs before takeoff. These tabs were left at a positive angle of 12 degrees rather than being set to neutral. This configuration forced the aircraft into a nose-up attitude immediately after rotation, leading directly to the stall and subsequent crash.
