## Discrepancy

CREW REPORTED MULTIPLE RIGHT ENGINE OIL PRESSURE MESSAGES ON DEPARTURE FROM MOB.  CREW RETURNED TO MOB AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED THE AIRCRAFT, REMOVED AND REPLACED THE AXIS-D CARBON SEAL (AT AIR TURBINE STARTER PAD) FOR THE RIGHT ENGINE ACCESSORY GEARBOX (AGB) AND PERFORMED CHECKS USING THE AIRCRAFT MAINTENANCE MANUALS.  AIRCRAFT WAS RELEASED FOR SERVICE.
