NTSB narrative
During an application flight, the pilot maneuvered the helicopter in order to conduct another pass, maintaining vigilance of the high lines and trees in the vicinity of his operations. The pilot stated that he did not see the 2 wires spanning from across the road into the bean field where he was applying insecticide. He flew right into the wires which subsequently entangled around the mast of the helicopter. During the forced landing to the field, the "controls locked up" and the helicopter spun to the right 3 times before impacting the ground. The helicopter was substantially damaged. The pilot reported no preimpact mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
Probable cause
The pilot did not see the wires resulting in the subsequent wire collision.

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.
