## Discrepancy

(CAN) ON APPROACH, CREW SELECTED GEAR DOWN AND BOTH MAIN GEAR REMAINED IN WHEEL WELLS.  CREW NOTED THAT GEAR DOORS WERE MOVING SLIGHTLY ON DOWN SELECTION. TWO MORE GEAR UP/GEAR DOWN SELECTIONS WERE REQUIRED BEFORE GEAR FINALLY EXTENDED AND LOCKED INTO THE DOWN POSITION. FERRY PERMIT WAS ISSUED AND AIRCRAFT RETURNED TO BASE WITH GEAR DOWN. MAINTENANCE FOUND THE PRESSURE SWITCH WHICH CONTROLS THE HYDRAULIC LANDING GEAR SYSTEM PUMP,  WHICH MAINTAINS SYSTEM PRESSURE,  WAS INTERMITTENT. PRESSURE SWITCH WAS REPLACED, GEAR SWINGS COMPLETED AND AIRCRAFT RETURNED TO SERVICE.
