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 an engine power surge, followed by a loud bang from the engine area, and a total loss of engine power. A piece of the snap ring from the turbocharger was found jammed between the oil scavenge pump gears and the oil scavenge pump case. This caused the oil pump to fail, resulting in no oil pressure and a total loss of engine power. The center section of the turbocharger had been rebuilt using automotive parts. The airplane's propeller, fuselage bulkheads and lower fuselage skin were bent during the emergency landing.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the failure of the turbocharger, caused by a unapproved rebuild of the turbocharger which contained automotive parts. Debris from the failed turbocharger damaged the oil pump resulting in lack of engine lubrication. Full narrative available
