The NTSB's narrative final · quoted from the NTSB record
The pilot stated he flew a total of 3 hours to two airports throughout the day. He stated that 5 miles from the third airport, he turned his landing light and carburetor heat on. Subsequently, both electrical and engine power were lost. The pilot stated he announced a "Mayday" call over the radio and performed a forced landing in hilly, rough terrain, resulting in substantial damage to the airplane. The pilot stated that after the impact he could immediately smell fuel in the cabin and was able to hear it dripping from the airplane. During the recovery of the airplane, one quart of fuel was recovered from the left wing. No further evidence of fuel was noted. An examination of the engine revealed no anomalies that would have precluded the engine from producing power prior to impact. The airplane battery was replaced and the electrical system functioned properly. An examination of the remaining systems revealed no anomalies.
