NTSB narrative
The pilot was enroute to the next field he would spray and used a handheld GPS unit to navigate. When he finished imputing information into the GPS, he looked up and saw power lines across his flight path. The pilot pulled up on the collective and cyclic to climb; however, the helicopter struck the upper power line. The pilot entered an autorotation, during which the pilot felt unusual vibrations, but had full authority of the flight controls. The helicopter settled into a mature stand of corn, which resulted in structural damage to the tail boom and main rotor system. The pilot stated that he should have climbed to 500 ft agl before he used his GPS to navigate to the next field.
Probable cause
The pilot’s failure to maintain clearance from power lines during low level aerial application operations due to a distraction.

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.
