## Analysis

WHILE SPRAYING AT DUSK, THE PLT WAS CONCERNED ABOUT INJURING A 'NON-TARGET CROP' ACROSS THE ROAD TO THE SOUTH FROM THE FIELD THAT WAS BEING SPRAYED. HE STATED THAT AN IRRIGATION SYSTEM WAS SITTING POINTED SOUTHWEST, AND THAT AS HE WAS ENTERING A SWATH TO THE NORTH, THE ACFT STRUCK THE EQUIPMENT. DURING THE COLLISION, 1 PROPELLER BLADE, THE RIGHT MAIN GEAR & A WING WERE DAMAGED. SUBSEQUENTLY, THE PLT LANDED IN THE FIELD & THE ACFT WENT UP ON ITS NOSE. THE PLT ADMITTED THAT HE SHOULD HAVE TAKEN MORE TIME TO SURVEY THE FIELD.
