Background
For about two months before the accident, the aircraft's electrical system had been operating improperly and failing to charge the battery. Although two maintenance shops had attempted to correct the problem, the system was still not functioning correctly as of the accident date. During this two-month period, the pilot continued to operate the aircraft, turning on the master switch only during engine start and for brief periods of radio transmission.
Accident Sequence
On the day of the accident, the pilot turned on the master switch to start the engine. He then headed for his destination without realizing he had left the master switch on. About 10 minutes after takeoff, the pilot smelled what he thought was either smoke or fumes from a malfunctioning heater and elected to make a precautionary landing.
While attempting to land in an open area near a county road, the aircraft collided with a power line that the pilot was trying to go under in order to reach the intended touchdown point. After hitting the power line, with the fumes getting stronger, the pilot tried to get the aircraft on the ground as quickly as possible. As a result, the aircraft touched down at an excessive descent rate, causing both main landing gear to collapse.
Post-Accident
Immediately after exiting the aircraft, the pilot noticed a small fire in the right wing root. He elected not to approach the aircraft to attempt to put out the fire, and it was eventually consumed by the flames.
