Narrative:The commercial-rated student pilot was practicing power recovery autorotations with a flight instructor (CFI) monitoring. The rotor rpm was allowed to deteriorate, which resulted in a hard landing. The main rotor blades flexed downward and severed the tail boom from the helicopter. Density altitude at the time was 11,300 feet.
Probable Cause: failure of the flight instructor (CFI) to properly supervise the flight and ensure that adequate rotor rpm was maintainted during the autorotation/landing. The high density altitude was a related factor.
