Probable cause

the pilot's failure to identify the wires prior to spraying the field and the low altitude at which the pilot was flying. A factor was the wires which the airplane contacted.

Analysis

The pilot made a swath run to the south. He made a turn back to the north and was flying another swath run at a slightly lower altitude when the airplane collided with two of three wires which crossed the field. The airplane decelerated, rolled 360 degrees, and impacted the terrain in an upright position. The being sprayed was at the bottom of a 'canyon'. The poles from which the wires were suspended were on hills on both sides of the canyon. This was the first time the pilot had sprayed this particular field and he was unaware of the wires.
