## Discrepancy

THE FLIGHT CREW REPORTED DURING PREFLIGHT CHECKS THE LOWER (L) PRE-CHECK LEVER WAS LEAKING FUEL. THE PLANNED FLIGHT WAS CANCELLED. THE MAINTENANCE VENDOR REMOVED AND REPLACED THE PRE-CHECK VALVE ASSEMBLY WITH A NEW UNIT. OPERATION AND LEAK CHECKS WERE SATISFACTORY. THE AIRCRAFT WAS RETURNED TO SERVICE.
