## Discrepancy

45 MIN INTO FLIGHT CREW GOT A HYD SYSTEM 1 ENGINE PUMP LIGHT ILLUMINATED.  THE CREW THEN TURNED ON HYD 1B ELECTRIC PUMP AND EVERYTHING RETURNED TO NORMAL.  SHORTLY THERE AFTER THEY NOTICED THE HYD QTY & PRESSURE ON THE #1 SYSTEM BOTH DROPPING.  THEY DIVERTED TO NEAREST SUITABLE AIRPORT (KCVG) WHERE THEY CALLED FOR EMERGENCY EQUIPMENT TO ROLL.  WE ARE WORKING ON GETTING ON-CALL MX AS WELL AS CONTRACTED MX ONSITE TO TROUBLESHOOT CAUSE.  WE WILL FOLLOW UP AFTER DISCOVERY.
