Read the full NTSB narrative

The instructor pilot reported that he and the student pilot were practicing power recovery autorotations at the Boise airport. During the tenth practice autorotation, with the student pilot on the controls, the instructor noted a lower than normal main rotor RPM (approximately 94 percent) and elected to take the controls in an effort to make the necessary inputs to recover from the maneuver. The instructor pilot reported that during the transition (approximately 60 feet agl), there was a "struggle" for the controls and corrective action was delayed resulting in a hard landing and substantial damage to the helicopter. The instructor pilot stated that he does not recall verbalizing the transfer of control to the student pilot.
