## Discrepancy

THE FLIGHT CREW REPORTED THAT THE FLAP HANDLE DOES NOT AGREE WITH THE FLAP POSITION INDICATOR.  THE MAINTENANCE TEAM TROUBLESHOT AND FOUND THE FLAP POSITION INDICATOR WAS DEFECTIVE.  THE POSITION INDICATOR WAS REMOVED AND REPLACED WITH AN OVERHAULED UNIT.  OPERATIONS CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
