## Discrepancy

ROC - FLT 4890 - WHEN SELECTING THE GEAR DOWN FOR LANDING, THE HYDRAULIC ANNUNCIATOR LIGHT ILLUMINATED AND THE GEAR FAILED TO EXTEND.  THE CREW NOTED THAT THE HYDRAULIC PUMP FAILED TO OPERATE.  THE CREW THEN PUMPED THE GEAR AND FLAPS DOWN, LANDING WITHOUT INCIDENT.  MAINTENANCE WAS DISPATCHED TO THE AIRCRAFT AND REPLACED THE HYDRAULIC PUMP AND MOTOR ASSEMBLY RETURNING THE AIRCRAFT TO SERVICE  (M)
