## Discrepancy

AT APPROX 60 KTS ROLL GOT NR 2 GREEN HYD PUMP LOW  PSI.  SAME LIGHT CAME ON AFTER START OF NR 1 ENGINE, BUT WENT OUT ON ITS OWN AFTER A MINUTE.   REJECTED TAKE OFF.  CONFERED WITH MAINT, DID A HIGH POWER ENGINE RUN WITH NO PROBLEM NOTED.  TAXI BACK FOR TAKEOFF, BUT GOT NR 1 GREEN HYD PUMP LOW PSI AT AROUND 60 KNOTS, REJECTED AGAIN.  IT IS POSSIBLE THAT IT WAS THE NR 1 PUMP BOTH TIMES.  HOWEVER, WE WERE FAIRLY SURE IT WAS THE NR 2 PUMP ON THE FIRST TIME.  MAINTENANCE REPLACED BOTH GREEN SYS EDP`S AND FILTERS.  MAINTENANCE ALSO PREFORMED GREEN SYS BLEED WITH FULL GEAR SWING.  ALL LEAK, OPERATIONS, FLUID LEVELS & AIR PRESSURES CHECK GOOD.  A/C RETURNED TO SERVICE.
