Then he followed the installation procedure, including the mast nut torque application. The mast nut torque application is a critical procedure, which ensures that the rotor assembly remains attached to the main rotor mast. He asked a mechanic to come and verify the mast nut torque.

Reducing the lift and decreasing the torque effect helped to stabilize the helicopter. The pilot lowered the collective lever by 50%, which decreases the pitch angle of the main rotor blades and thus reduces the lift generated by the rotor. They crashed into a field east of the runway, breaking the skids off.
