## Discrepancy

(CAN) UPON LANDING AND DURING COOL DOWN PILOT NOTICED A FUNNY ODOR AND HEARD A SQUEALING NOISE.  FOLLOWING SHUTDOWN HE NOTICED THE ALTERNATOR BELT SMOKING AND CALLED MAINTENANCE.  THE ALTERNATOR LIGHT NEVER DID COME ON.  WHEN MAINTENANCE ARIVED THE ALTERNATOR WAS COMPLETELY SIEZED.  THE ALTERNATOR WAS DISSASEMLED TO INVESTIGATE THE CAUSE AND DETERMINED IT WAS A FWD BEARING FAILURE.
