## Discrepancy

PILOT REPORTED THE HYDRAULIC PUMP WAS RAPIDLY CYCLING WHILE IN CRUISE FLIGHT.  PILOT EXTENDED THE LANDING GEAR NORMALLY AND HYDRAULIC OPERATION RETURNED TO NORMAL.  PILOT LANDED AT HIS DESTINATION WITHOUT FURTHER INCIDENT.  CORRECTIVE ACTION INVOLVED REPLACING THE HYDRAULIC POWER PACK.  SUBSEQUENT LANDING GEAR RETRACTION OPERATIONAL CHECKS WERE SATISFACTORY.
