What happened
Shortly after departing Balkhash Airport, the aircraft entered cloud cover while climbing. Control was subsequently lost as the plane banked to the right and began losing altitude. The right wing detached due to excessive aerodynamic forces, causing the aircraft to dive uncontrolled into the ground. The impact occurred in an isolated area approximately 39 km northwest of the airport. Search teams located the wreckage ten days later on October 10, confirming that all 15 occupants were killed.
Findings
The investigation concluded that the pilot in command experienced spatial disorientation while climbing into the clouds. This loss of orientation led to uncontrolled maneuvers that generated aerodynamic loads exceeding the structural limits of the right wing, resulting in its detachment and the subsequent crash.
