## Discrepancy

DURING CRUISE, PILOT NOTICED OIL COMING OUT OF THE TURBOCHARGER VENT AND ENGINE COWLING ON THE RIGHT ENGINE.  THE STARTER/ADAPTER SPRING CLUTCH WAS FOUND TO HAVE APPARENTLY FAILED AND AT LEAST ONE PIECE OF THE SPRING CAME INTO CONTINUOUS CONTACT WITH THE STARTER SHAFT GEAR ASSY CAUSING STARTER SHAFT GEAR TO FAIL.
