## Discrepancy

(CAN) DURING FLIGHT, CREW NOTICED NR 2 HYDRAULIC SYS FLUID DEPLETING.  THEY RETURNED TO THEIR DEPARTURE AIRPORT FOR AN UNEVENTFUL LANDING.  MAINTENANCE FOUND THE RT NACELLE FLIGHT SPOILER UNLOAD VALVE HAD 2 BOLTS WITH THE HEADS SHEARED FROM THE VALVE BODY.  THIS WAS THE CAUSE OF THE LEAK. THE VALVE WAS REPLACED AND THE AIRPLANE RETURNED TO SERVICE.
