## Discrepancy

(CAN) SHORTLY AFTER TAKE-OFF THE PILOT HEARD A "BANG" FROM THE RT ENGINE AND NOTICED A LOSS OF MANIFOLD PRESSURE.  HE THEN RETURNED TO THE AIRPORT WITH NO PROBLEMS ENROUTE.  MX FOUND THE TURBO CHARGER SHAFT BEARING HAD FAILED.  THE TURBO CHARGER WAS REPLACED, OIL SUMP CLEANED, OIL FILTER REPLACED AND GROUND RUN ACCEPTABLE.
