## Discrepancy

DFW FLT1262 - DURING FINAL APPROACH TO DFW, CREW SELECTED FLAPS FROM 15 TO 25 UNITS AND NOTICED A DEVELOPING SPLIT IN THE LEFT AND RIGHT FLAP POINTERS.  AT 25 UNITS, THERE WAS A NOTICEABLE SPLIT BUT NO APPARENT AIRCRAFT ROLL.  CREW EXECUTED A GO-AROUND AND LANDED WITH FLAPS 15 WITHOUT FURTHER INCIDENT.  SUBSEQUENT TEST AT THE GATE SHOWED THE FLAPS GOING TO 25 UNITS WITH A 3 TO 4 SPLIT, THEN 30 UNITS WITH NO SPLIT AND 40 UNITS WITH NO SPLIT.  MAINTENANCE FOUND THE FLAP POSITION INDICATOR FAULTY.  REPLACED INDICATOR PER MM 27-51-00 AND 27-58-01.  OPERATIONAL CHECK GOOD.
