Analysis

The airplane contacted a guy wire and collided with the terrain during an aerial application flight. The pilot reported he saw the poles during the aerial application flight. He reported he knew that there would be wires in the area so he swung out wide during a turn to look for the wires. The right wing contacted a guy wire during the turn. The airplane then settled into the sunflower crop.
