## Discrepancy

ON TAKEOFF THE ANALOG FLAP INDICATOR BOUNCED BACK AND FORTH BETWEEN 0-15 DEGREES, SETTING OFF THE TAKEOFF AURAL WARNING SYSTEM.  ALSO, EACH TIME IT WENT TO 0 DEGREES, RECEIVED FLAP AND ADVANCED SWS WARNINGS ON THE MAP.  OPERATED FLAPS SEVERAL TIMES, COULD NOT DUPLICATE.  REMOVED AND REPLACED FLAP CONTROL UNIT IAW EMB120 MM 25-50-06 FOR TROUBLESHOOTING.  OPS CHECK GOOD.
