Aircraft Accident/Incident Report

Indianapolis, Indiana 46237
Wednesday, December 20, 1995 20:30 EST

NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

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.
