## Discrepancy

ON APPROACH WITH FLAPS SELECTED TO APPROACH POSITION,  THE INDICATOR SHOWED NO MOVEMENT AND AFTER VISUAL CHECK NOTICED FLAPS STILL IN THE UP POSITION. FOLLOWED THE NO FLAP/UNKNOWN POSITION CHECKLIST. LANDING WAS UNEVENTFUL. MAINTENANCE REPLACED A FAULTY FLAP UP LIMIT SWITCH. FLAP OPERATIONAL CHECKS WERE GOOD. AIRCRAFT WAS RETURNED TO SERVICE.
