Analysis

The acft was found floating inverted about 1.5 mi from the point of departure. The tailboom had separated & there was evidence that the m/r blades had struck the tailboom. The windshield & chin bubble was broken out. An oil pump gear tooth was found adhering to the lower chip detector plug. The oil pump had 3 teeth missing from a gear. There was evidence of a smooth round object going through the pump & jamming the gear teeth. The ball separator gage for a bearing (mrc p/n 6859435-G) had broken apart allowing balls to fall out. The gear which drives the fuel control & oil pump then moved sideways FAR enough to become uncoupled from its drive gear. The seven tangs on one-half of the ball separator cage had separated. The separated bearing was not an authorized type for use in this engine. The engine manufacturer issued a commercial engine bulletin dated 9/30/82 calling for all unauthorized bearings to be removed from spare stock & scrapped.
