## Discrepancy

PILOT EXPERIENCED THE HYDRAULIC PUMP CYCLING CONTINUOUSLY TO HOLD PRESSURE, FOLLOWED BY PARTIAL GEAR EXTENSION.  THE PILOT EXTENDED THE LANDING GEAR USING EMERGENCY PROCEDURES AND LANDED WITHOUT INCIDENT.  CORRECTION ACTION INVOLVED REPLACING THE HYDRAULIC POWER PACK ASSEMBLY.  SUBSEQUENT OPERATIONAL CHECKS WERE SATISFACTORY.
