NTSB Narrative Summary Released at Completion of Accident

The pilot was practicing autorotations into an off airport open field. The landing was hard, and the pilot received serious injuries. The pilot reported the he felt a shudder during the autorotation, and tried to regain airspeed by using forward cyclic, but he was unable to regain airspeed. Examination of the helicopter found evidence of low main rotor rpm. No discrepancies were found with the flight controls and engine.

NTSB Probable Cause Narrative

The pilot's improper use of the collective, and failure to maintain main rotor rpm, which resulted in low main rotor rpm and a hard landing.
