## Discrepancy

(CAN) THE FLIGHT CREW REPORTED THAT THE NR 2 ENGINE DRIVEN PUMP CAUTION LIGHT CAME ON DURING LANDING GEAR EXTENSION. MAINTENANCE DISCOVERED THE NR 2 HYDRAULIC SYSTEM HAD AIR IN IT AND ALSO THE NR 2 SPOILER LIFT DUMP PRESSURE LINE BETWEEN THE LIFT DUMP VALVES WAS LEAKING FROM A PIN HOLE. THE HYDRAULIC TUBE WAS REPLACED, THE SYSTEM WAS BLED AND ALL FURTHER CHECKS WERE COMPLETED PRIOR TO RELEASING THE AIRCRAFT TO SERVICE.
