## Discrepancy

CLE - DURING LANDING APPROACH, WHILE SELECTING FLAPS FROM 15 TO 25, THE RIGHT FLAP INDICATION STAYED AT 15 AND FLAPS STOPPED MOVING WITH A SPLIT OF ABOUT 4 DEGREES.  DURING MISSED APPROACH, FLAPS MOVED TO 25.  SELECTED FLAPS 30 AND SPLIT OCCURRED AGAIN.  AFTER 20 SECONDS MOVED TO 30 DEGREES.  FLIGHT LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE FLAP POSITION INDICATOR PER MM 27-58-41.  OPERATIONAL CHECK GOOD.
