NTSB narrative
The pilot was finishing an agricultural application to an orchard when a witness observed the helicopter enter a steep right bank and then descend into the orchard. The helicopter was found lying on its right side, and several trees near the wreckage were damaged. The pilot could not recall the circumstances of the accident. A postaccident examination of the airframe and engine revealed no mechanical malfunctions or failures that would have precluded normal operation. It is likely that, during the application, the pilot did not maintain sufficient clearance from the trees, which resulted in a collision with the trees, loss of control, and subsequent impact with the ground.
Probable cause
The pilot’s failure to maintain clearance from trees during a low-altitude agricultural application, which resulted in a loss of control and impact with the ground.

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.
