Event Location
Probable Cause
The pilot's failure to maintain clearance from power lines while maneuvering.
Full Narrative
The pilot stated that he was spraying a swath of field bordered by power lines. After making a pass, the pilot's attention was focused on a pole and he struck nearby power lines, which wrapped around the propeller. The pilot noticed a sudden loss in power and thought he could make it back to the airport. The power loss increased and the pilot initiated a forced landing into a field, resulting in a hard landing. The engine detached from the airplane and both wings and fuselage sustained substantial structural damage. The pilot reported no mechanical failures or malfunctions that would have precluded normal flight.
