Analysis

The agricultural airplane was destroyed after it struck power lines and impacted terrain in an open field. The pilot stated that as he completed his last spray run on a rice field, he departed the area to the south, gained altitude, and impacted the power lines running perpendicular across the field. No mechanical problems with the airplane were reported prior to the accident.
