## Discrepancy

PHL - FLT238 - ON APPROACH TO PHL FROM DFW, CREW REPORTED THE FLAPS WOULD NOT MOVE FROM 10 UNITS TO 15 UNITS WHEN SELECTED.  CREW EXECUTED A MISSED APPROACH, AND DURING GO-AROUND, FLAPS ADJUSTED THEMSELVES AND INDICATED 15 UNITS.  FLIGHT MADE A FLAPS 15 LANDING WITHOUT INCIDENT.  NO EMERGENCY WAS DECLARED.  MAINTENANCE REMOVED AND REPLACED THE FLAP POSITION TRANSMITTERS PER MM 27-58-12-004.  OPERATIONAL CHECK OF FLAPS GOOD.
