NTSB narrative
WHILE IN CRUISE FLIGHT OVER ROUGH UNEVEN TERRAIN, THE HELICOPTER'S ENGINE LOST PARTIAL POWER AND THE PILOT MADE AN AUTOROTATION LANDING IN A CORN FIELD. THE PILOT STATED THAT DUE TO UNEVEN TERRAIN, HE '...MADE [THE] DECISION TO ZERO OUT AIRSPEED DURING TOUCHDOWN.' THE PILOT STATED HE LEVELED THE HELICOPTER AND '...PULLED COLLECTIVE TO CUSHION.' DURING THE LANDING A MAIN ROTOR BLADE SEPARATED THE TAIL BOOM FROM THE FUSELAGE. EXAMINATION OF THE HELICOPTER DID NOT DISCLOSE EVIDENCE OF MECHANICAL MALFUNCTION.
Probable cause

- 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. 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.
