Analysis

The student had been released to overfly an airport approximately eight miles to the south and return for landing. He was instructed to maintain 1,000' MSL for the flight. The student pilot departed the traffic pattern approximately 40 minutes before sunset. The airplane impacted a television tower. A witness reported the airplane lights were not on as the airplane flew over his house. Prior to the accident the student became disoriented. He reported to his instructor pilot, over the radio, taht he could see the tower. He was told to fly north by the instructor, the student responded he was having difficulty seeing his instruments. The instructor pilot instructed him to turn on his instrument lights, the students response was he could not find the switch for the instrument panel lighting. Radio communication was lost with the student while the instructor pilot was trying to direct him to the switch.
