## Discrepancy

THE FLIGHT CREW REPORTED THAT DURING PREFLIGHT CHECKS THAT THE LEFT ENGINE FUEL FLOW INDICATOR WAS READING ZERO WITH THE ENGINE RUNNING. THIS DISCREPANCY CAUSED THE FLIGHT TO BE CANCELLED. THE MAINTENANCE VENDOR TROUBLESHOT AND DETERMINED THAT THE LEFT ENGINE FUEL FLOW TRANSMITTER WAS DEFECTIVE. THE MAINTENANCE VENDOR REPLACED THE TRANSMITTER WITH AN OVERHAULED UNIT. OPS AND LEAK CHECKS WERE SATISFACTORY. THE AIRCRAFT WAS RETURNED TO SERVICE.
