## Discrepancy

DURING INSPECTION, THE NR 8 FLIGHT SPOILER ACTUATOR WAS FOUND STATICALLY LEAKING FROM THE INPUT LINKAGE ASSEMBLY.  THE FLIGHT SPOILER WAS OPERATED WITH NO CHANGE TO THE LEAK RATE.  THE ACTUATOR WAS REPLACED AND OPERATIONALLY CHECKED WITH NO LEAKS FOUND.  THERE WAS NO MEASURABLE FLUID LOSS FROM THE HYDRAULIC SYSTEM.
