Summary

The pilot was making aerial application runs to two fields that had high tension power lines running between them.

The smaller wire, which was 73 feet above the ground, was not marked and there were no poles for this wire between high tension lines and the substation. After contacting the wire, the pilot flew the airplane back to the departure airport. The airplane sustained substantial damage to the right wing due to the wire strike.
