## Discrepancy

SHIP 9506-ATB- THE FLIGHT CREW PERFORMED AN AIR TURN BACK DUE TO A RIGHT HYDRAULIC SYSTEM FAILURE. AN EMERGENCY WAS DECLARED WITH ATC. THE LANDING WAS UNEVENTFUL EXCEPT FOR THE MAIN LANDING GEAR DOORS CONTACTING THE RUNWAY UPON ROLLOUT. CORRECTIVE ACTION: MAINTENANCE REPLACED THE RIGHT MAIN LANDING GEAR TRANSFER VALVE AND DEFERRED BOTH DOOR BUMPERS TO MONITOR FOR BUMPER REPLACEMENTS. THE AIRCRAFT HAS RETURNED TO SERVICE.
