The helicopter made a hard landing and caught fire.
There were six people on board: three crew members, two medics and a female patient.
"Two pilots were killed, the rest of the people on board were taken to the hospital," said Jan Strizhov, senior assistant to the head of the department.
Conclusion
The cause of the aviation incident involving the Mi-8T helicopter, registration RA-22330, was the disconnection of the lateral control system in flight due to the displacement of bolt KAU30b-022 from its standard position on the hydraulic booster KAU30b of the lateral control system.
Despite organized search efforts, the bolt was not found, making it impossible to definitively determine the reason for its absence from its standard position.
The failure of the lateral control system led to the helicopter's collision with the ground surface.
