## Discrepancy

UPON APPROACH WHEN LANDING GEAR SELECTED DOWN, GEAR WOULD NOT EXTEND.  FLIGHT CREW USED THE MANUAL GEAR DOWN HAND PUMP TO EXTEND GEAR SUCCESSFULLY AND LANDED.  MAINTENANCE DISCOVERED HYDRAULIC POWER PACK CIRCUIT BREAKER WAS TRIPPED.  RESET CIRCUIT BREAKER AND PERFORMED GEAR SWING AND COULD NOT DUPLICATE.  AIRCRAFT RETURNED TO SERVICE.
