## Discrepancy

THE CREW REPORTED THAT DURING CLIMB OUT, THEY RECEIVED A HYD SYS 2 LOW MESSAGE. THE CREW COMPLETED THE AOM EMERGENCY AND NORMAL CHECKLIST.  LATER THEY FOUND THE NR 2 HYD QTY WENT INTO THE AMBER RANGE.  THE SYS MAINTAINED PRESSURE, BUT LATER IN FLIGHT THE CREW GOT A SYS NR 2 FAIL.  THE CREW DECLARED AN EMERGENCY AND DIVERTED.  
THE ACFT LANDED WITHOUT INCIDENT.  THE ACFT WAS REMOVED FROM SERVICE.  R & R THE NR 2  HYD PUMP IAW AMM 29-10-03.  THE OPS AND LEAK CHECKS WERE GOOD.  R & R THE HYD PUMP 2 FILTERS IAW AMM 29-10-08.  LEAK CHECK GOOD AND NO CONTAMINATION FOUND.  THE ACFT WAS RETURNED TO SERVICE.
