NTSB narrative
The pilot reported that, during an aerial application flight, he made multiple passes over the field, while avoiding power lines. On the accident pass, the helicopter struck one of the power lines suspended above the field with the center of the rotor mast. The helicopter subsequently impacted terrain. The helicopter sustained substantial damage to the fuselage, tail boom, and main rotor blades during the accident sequence. The pilot reported that there were no preimpact mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
Probable cause
The pilot’s failure to maintain clearance from power lines during low-level agricultural spray operations.

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, cause areas. 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.
