The NTSB's narrative final · quoted from the NTSB record

The pilot was on a local flight to demonstrate the airplane to someone interested in purchasing the same make and model. While on final approach, the airplane lost power and came to rest suspended in a tree during the subsequent forced landing. The Fire Chief responded to the scene. He said, 'The nose was straight down in the trees. The fuel was dripping from the right wing, whether it was running from the left side and dripping from the right, I can't tell you.' Examination of the airplane by a Federal Aviation Administration (FAA) Airworthiness Inspector revealed the left fuel tank was compromised during the accident sequence. The right fuel tank was intact and contained no fuel. The airplane's engine started and ran on the airframe utilizing the airplane's own fuel system. The pilot said that a review of his records revealed the airplane had flown approximately 2-2.5 hours since the last fuel service. The pilot estimated his fuel burn rate averaged 10 gallons per hour. The airplane had a fuel capacity of 26 gallons per wing tank for a total of 52 gallons.
