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 departed with the intention of circling the airport several times to check the aircraft prior to departing on a cross-country to Prescott, Arizona. The airplane was undergoing a major rebuilding and restoration after a previous accident and had not flown for several years. Postcrash examination revealed that two oil cooler lines had been inadvertently crossed. One of the oil cooler lines failed as a result of the incorrect line installation and the engine oil was pumped overboard. The engine subsequently sustained a catastrophic internal failure. The last logbook entry and documented annual inspection for the airplane was dated 1987. The pilot's last flight physical was dated 1981. Ground witnesses stated that the pilot did not go through the normal preflight ground power checks prior to flight.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the pilot's decision to fly an unairworthy and uncertificated airplane, his failure to perform an adequate preflight, and the improper installation of the oil cooler lines. Full narrative available
