NTSB narrative
The certificated flight instructor (CFI) and his passenger were flying about 2 miles offshore. The helicopter had just completed a turn at about 100 feet above the water when the low main rotor rpm horn sounded. When an adjustment of the throttle failed to remedy the situation, the CFI entered an autorotation. The tail of the helicopter stuck the water during the flare, which resulted in the helicopter entering an uncontrollable spin. The helicopter immediately sank and at the time of this writing, has not been located or recovered. The helicopter’s flight manual showed that at the time of the accident, the flight was being operated within a region of performance in the height-velocity diagram that the manufacturer recommended avoiding. A review of the helicopter’s maintenance records did not reveal any discrepancies with the helicopter prior to the accident flight.
Probable cause
A loss of main rotor rpm for undetermined reasons.

Source notes (4)
- 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.
