## Discrepancy

(CAN) ON APPROACH, THE LANDING GEAR WAS SELECTED DOWN BUT SYSTEM FAILED TO OPERATE.  THE MANUAL EXTEND SYSTEM WAS USED AND AN UNEVEVENTFUL LANDING WAS COMPLETED.  UPON INSPECTION BY MAINTENANCE, THE RELAY CONTACTS FOR THE HYDRAULIC PUMP WERE FOUND TO HAVE SOME CONTACTS CORRODED.  THE RELAY WAS REPLACED.
