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.
Probable cause
Inadequate communications between the certified flight instructor and student pilot, and the student pilot's delay in relinquishing controls resulting in a hard landing during a practice autorotation.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
