NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE PILOT STATED THAT THE FIELD TO BE SPRAYED APPEARED SAFE ENOUGH WHEN HE FLEW A RECON FLIGHT OVER THE AREA THE DAY PRIOR TO THE ACCIDENT. HE STATED THAT HE DIDN'T EXPECT THE POWER TRANSMISSION LINES TO BE SO LOW, AND THAT HE DID NOT SEE A RISE IN THE CULTIVATED TERRAIN JUST UNDER THE POWERLINES. THE DAY OF THE ACCIDENT, AS THE PILOT FLEW UNDER THE LINES AND OVER THE HUMP IN THE CORNFIELD, THE RIGHT SPRAY BOOM SNAGGED THE CORN, PULLING THE RIGHT WING DOWN. THE AIRCRAFT THEN SWERVED 180 DEGREES AND IMPACTED THE TERRAIN BEFORE COMING TO REST.
