## Discrepancy

THE BASE MAINTENANCE TEAM FOUND DURING POST-FLIGHT CHECKS THE STEERING UNIT LEAKING. THE MAINTENANCE PROVIDER REMOVED THE LEAKING NOSE WHEEL STEERING ACTUATOR AND REPLACED WITH AN OVERHAULED ACTUATOR. OPERATIONAL AND LEAK CHECKS WERE SATISFACTORY. THE AIRCRAFT WAS RETURNED TO SERVICE.
