## Discrepancy

(CAN) DURING CLIMB, PILOT NOTICED THAT BOTH HYDRAULIC PUMPS WERE CYCLING MORE THAN NORMAL, BUT ALSO NOTICED THAT THE HYDRAULIC FLUID WAS MAINTAINING ITS LEVEL.  AIRCRAFT LANDED AND PILOT NOTICED FLUID BY THE TAIL WHEEL WITH NO REAL SIGNIFICANT LOSS OF FLUID.  O-RING ON UPLOCK HAD BLOWN.  UPLOCK REPLACED.
