## Discrepancy

THE FLIGHT CREW REPORTED THAT DURING POST FLIGHT CHECKS HYDRAULIC FLUID WAS FOUND LEAKING FROM GANG DRAIN. THE MAINTENANCE VENDOR DETERMINED THE NO1 HYDRAULIC ACCUMULATOR WAS DEFECTIVE. A REPAIRED ACCUMULATOR WAS INSTALLED. OPERATIONAL AND LEAK CHECKS WERE SATISFACTORY. THE AIRCRAFT WAS RETURNED TO SERVICE.
