NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot reported that he recently purchased the aircraft and was in the process of getting it into flyable condition so it could be moved to a maintenance facility at another airport. The pilot stated that after draining and refilling the fuel system several times, he believed that all water had been purged from the system. After a high speed taxi test the pilot decided to try one pattern circuit. Shortly after the takeoff, the engine quit completely. The aircraft had insufficient altitude to return to the airport and the pilot landed in a rock quarry. The airport manager said that the aircraft had been parked on the airport for 6 years, and to his knowledge had not flown in that time. The pilot told the fuel facility staff while he was purchasing 15 gallons of aviation gasoline in metal cans that he had drained a lot of water from the tanks and was still getting some. No records have been found of any annual inspection or other maintenance activity by aircraft mechanics on the aircraft since 1991. The FAA had not issued a ferry permit to move the aircraft.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: fuel system contamination and the pilot's intentional operation of a known unairworthy aircraft. Full narrative available
