The pilot reported that, during an agricultural application flight, he made six passes underneath power wires to complete the applications. On the seventh pass underneath the power wires, the wire deflector cable and the vertical stabilizer struck the wires. The pilot asserted that the vertical stabilizer jammed the rudder to the left, and the airplane entered a skidding left turn and then impacted terrain. The airplane was consumed by fire.
