What happened
A cargo operation departing from a remote location approximately 75 km from Kirensk ended in an accident during the initial climb phase. The aircraft was transporting five barrels of oil at the time of the incident.
As the plane ascended, the unsecured cargo moved within the fuselage. This movement caused the aircraft's center of gravity to shift outside of its safe operating limits. In response to the instability, the pilot attempted to perform an emergency landing. However, while flying at an altitude of roughly 15 meters, the aircraft entered a stall and struck the ground.
Despite the impact, there were no injuries reported among the crew.
Findings
The primary factor in the accident was the unstable center of gravity caused by the shifting of the oil barrels during the climb phase.
