Analysis

The Federal Aviation Administration inspector reported that he discussed the accident with the pilot. The pilot indicated to the FAA inspector that he was conducting aerial application operations. He was flying over the field and going to pass below a power line. As he neared the power line, he noticed a vehicle on the road. The pilot gained altitude in order to provide separation between the airplane and the vehicle. As the airplane gained altitude, it collided with the power lines. The airplane then descended into the terrain. There were no mechanical anomalies reported with the airplane. At the time of this report, the pilot did not submit NTSB Form 6120.1/2, the Pilot Operator Report.
