## Discrepancy

THE FLIGHT CREW REPORTED THAT THE NO3 ENGINE FUEL FLOW INDICATES ZERO, THE MAINTENANCE VENDOR TROUBLESHOT AND DETERMINED AN DEFECTIVE FUEL FLOW TRANSMITTER. THE DEFECTIVE TRANSMITTER WAS REMOVED AND A REPAIRED UNIT WAS INSTALLED. OPS CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
