## Discrepancy

(CAN) THE FLIGHT CREW CALLED MX ENROUTE, ADVISING A BLEED TRIP ON THE NR 2 ENGINE. THE CREW RAN THE CHECKLIST AND WAS ABLE TO RESET THE SYS ON THE SECOND ATTEMPT.  FOR COMPANY CONVENIENCE IT WAS DECIDED TO DIVERT TO A STATION WHERE PARTS AND MANPOWER WERE AVAILABLE.  MX LOCKED OUT THE HIGH STAGE VALVE AND THE FLIGHT CONTINUED TO THE FINAL DESTINATION WITH AN MEL APPLIED TO THE SYS AND NO FURTHER ISSUES REPORTED BY THE CREW.  AFTER FURTHER INVESTIGATION BY MX IT WAS DETERMINED THE PRECOOLER VALVE FAILED AND WAS REPLACED.
