## Discrepancy

ON DESCENT, CREW NOTICED HYDRAULIC SYSTEM PRESSURE WAS INDICATING TOO HIGH.  THE HIGH HYDRAULIC SYSTEM PRESSURE CHECKLIST REQUIRES A NO FLAP LANDING AND USE OF EMERGENCY BRAKES TO STOP THE AIRCRAFT.  EMERGENCY DECLARED.  DUE TO IT'S LONGER RUNWAY LENGTH,  ACFT DIVERTED TO KORF FOR LANDING.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE HYDRAULIC PRESSURE TRANSDUCER AND REPAIRED A BROKEN WIRE IN THE TRANSDUCER WIRING HARNESS.  THE LANDING GEAR WAS CYCLED SEVERAL TIMES TO BLEED THE HYDRAULIC SYSTEM.  THE BRAKES WERE BLED AND THE NITROGEN BOTTLE WAS SERVICED.  OPERATIONAL CHECKS OF THE HYDRAULIC INDICATION SYSTEM AND LANDING GEAR SYSTEMS WERE NORMAL.  THE AIRCRAFT WAS RETURNED TO SERVICE.
