According to the pilot, the airplane was fueled the day prior to the accident and flown 246 miles. Prior to the accident flight, which was 213 miles, the pilot added approximately 2 gallons of fuel to the main fuel tanks, which provided about 13 total gallons of fuel on board for the flight. While enroute to the intended destination the pilot made an unexpected landing to accommodate the needs of a passenger and was on the ground for about 8 minutes. The remaining portion of the flight was uneventful until approximately 12 miles from the destination airport when the airplane experienced a total loss of engine power. The pilot attempted to land on a nearby road; however, the airplane impacted tree tops and came to rest in a nose down attitude, which resulted in substantial damage to the fuselage and wings. According to a report from the Sheriff's Department, the passenger stated "they ran out of fuel." Postaccident examination revealed about one quart of fuel remained in the fuel system and there was no evidence of mechanical malfunction or any other abnormalities that would have precluded normal operation.
