Aircraft Accident/Incident Report

Wyoming, Illinois 61491
Thursday, July 12, 2007 19:37 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot had completed spraying most of the field during the aerial application flight and was making clean-up passes when the left wing contacted four wires of high-tension power lines. Data retrieved from a global positioning system receiver on board the airplane indicated the pilot sprayed the field by flying an east-west pattern crossing the power lines. He then began making the clean-up passes in a southeast to northwest direction. The accident occurred the second time he crossed the power lines during the clean-up passes. Inspection of the airplane and engine did not reveal any pre-existing mechanical failure/malfunction, which would have resulted in the accident.

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance with the power lines during the aerial application flight. Contributing to the accident were the power lines and the low altitude.
