NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot was making an aerial application pass at the south end of a field when the accident occurred. A 30-foot-tall power line ran north and south through the middle of the field. The pilot stated he was paying attention to the trees along the south end of the field during the pass when he realized that he was approaching the wires. He was unable to climb over the wires so he decided to fly under them. In doing so, the airplane contacted 7-foot-high corn and the airplane was pulled down into the field. Substantial damage resulted to the lower wings and the main landing gear mounting truss.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to pay attention to the power lines and his subsequent failure to maintain clearance from the corn field during the aerial application flight.
