Probable cause
The pilot’s failure to maintain clearance from powerlines during low-altitude maneuvering.
NTSB analysis
The pilot reported that, while conducting an aerial application on a field, he overflew one set of powerlines, however, struck the second set of powerlines shortly after. Subsequently, the helicopter impacted terrain and came to rest on its left side substantially damaging the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
