## Discrepancy

IN FLIGHT, THE LANDING GEAR HYDRAULIC PUMP CIRCUIT BREAKER POPPED WITH THE GEAR UP, THE GEAR WAS LOWERED AND A SAFE LANDING WAS MADE.  AIRCRAFT WAS PLACED ON JACKS AND THE GEAR SYSTEM WAS OPERATIONAL CHECKED.  WITH THE GEAR UP AND LOCKED THE HYDRAULIC PUMP WOULD NOT SHUT OFF, A TAP TO THE UP LOCK ASSEMBLY SHUT THE PUMP OFF.  UP LOCK ASSEMBLY WAS REMOVED AND INSTALLED A NEW UP LOCK ASSEMBLY.  OPERATIONAL CHECK OF THE GEAR SYSTEM CHECKED NORMAL.  UP LOCK ASSEMBLY WAS SENT IN FOR WARRANTY.
