## Discrepancy

DURING CLIMB PHASE, CREW REPORTED "OIL LEVEL LOW - R" CAS MESSAGE. THE CREW CHECK THE RIGHT ENGINE OIL QUANTITY AND FOUND IT 8 QUARTS LOW.  SHORTLY THEREAFTER, IT DROPPED TO 8.5 QUARTS LOW.  CREW DECIDED TO DIVERT AND LAND AS SOON AS PRACTICAL.  5 MINUTES FROM LANDING THE OIL PRESSURE WAS AT 35 AND CREW DECIDED TO SHUT DOWN THE RIGHT ENGINE.  MAINTENANCE PERSONNEL FOUND THE RIGHT ALTERNATOR GARLOCK SEAL LEAKING.  THE SEAL WAS REPLACED.
