## Discrepancy

ON APPROACH, CREW REPORTED THE FLAP INDICATOR SHOWED A 1/2 NEEDLE SPLIT BETWEEN 10 & 15.  CREW ACCOMPLISHED GO-AROUND.  FLAPS WERE NOT MOVEABLE UNTIL AFTER LANDING.  FLAPS RETRACTED AND WORKED NORMALLY AFTER LANDING.  MAINTENANCE REMOVED AND REPLACED THE FLAP POSITION INDICATOR PER AMM 27-58-01 FIGURE 101 AND 27-58-41-004-001.  RAN OPS CHECK OF FLAP SYSTEM.  SYSTEM OPS CHECKS GOOD.  AIRCRAFT OK FOR SERVICE.
