## Discrepancy

(CAN) THE AIRCRAFT EXPERIENCED A FLIGHT TURNBACK DUE TO TOTAL LOSS OF HYDRAULIC FLUID FROM THE NR 2 HYDRAULIC SYSTEM. BECAUSE OF THE FLUID LOSS AN EMERGENCY EXTENSION OF THE LANDING GEAR HAD TO BE CARRIED OUT PRIOR TO LANDING. THE CAUSE OF THE FLUID LOSS WAS DUE TO A CATASTROPHIC FRACTURE FAILURE OF LT HAND OUTBOARD SPOILER ACTUATOR METAL BODY, ALLOWING THE WHOLE CONTENT OF THE NR 2 HYD SYSTEM TO BE RELIEVED THROUGH THE ACTUATOR BODY.
