## Discrepancy

ON APPROACH TO FLL, CREW REPORTED A SPLIT FLAP INDICATION ON INDICATOR WHEN SELECTING FLAPS 25.  NO ROLL PROBLEMS WERE ENCOUNTERED.  CREW SELECTED FLAPS 15 AND ACCOMPLISHED A GO-AROUND.  INDICATOR WENT TO NORMAL.  FLIGHT LANDED WITHOUT FURTHER INCIDENT.  PER FAULT ISOLATION, MM 27-51-00 CALLED OUT FOR REPLACEMENT OF FLAP POSITION INDICATOR.  MAINTENANCE REMOVED AND REPLACED THE FLAP POSITION INDICATOR PER MM 27-58-41.  OPERATIONAL CHECK GOOD.
