A witness observed the helicopter depart and begin aerial spray operations in a corn field. He turned away and heard a loud “pop,” then turned around to see the helicopter collide with a power line guy wire and the ground before bursting in flames. A postaccident examination of the airframe, flight controls, engine assembly, and accessories revealed no anomalies.
Probable Cause: The pilot's failure to maintain clearance from power lines during an aerial application flight.
