NTSB narrative
The pilot reported to local law enforcement that while conducting an aerial application flight, the helicopter impacted power lines. He said that while he had crossed over the power lines multiple times during the application flight; however, the sun was blocked by a cloud and the power line was not visible due to the lack of a reflection off the line. The helicopter sustained substantial damage to the main rotor mast. According to a Federal Aviation Administration inspector that examined the helicopter on scene, he reported that there were no mechanical malfunctions or failures that would have precluded normal operations.
Probable cause
The pilot’s failure to maintain clearance from power lines during an aerial application flight.

- 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: local date, investigation status, coordinates, cause areas. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2020-03-12.
