## Discrepancy

AIRCRAFT LOST B-SYSTEM HYDRAULICS WHILE EN ROUTE.  THE AIRCRAFT WAS DIVERTED TO EWR WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE HYDRAULIC LEAK ON THE RT ELECTRIC B-PUMP PRESSURE ACCESS PLUG.  THE O-RING ON THE PLUG WAS FOUND BROKEN.  THE O-RING WAS REMOVED AND REPLACED.  THE B-SYSTEM HYDRAULIC RESERVOIR WAS SERVICED TO FULL PER MM 12-12-00.  LEAK AND OPERATIONAL CHECKS DURING RUN OF B-SYSTEM HYDRAULIC PUMPS WERE GOOD.
