## Discrepancy

THE TAT CIRCUIT BREAKER POPPED FOLLOWED BY SMOKE IN THE COCKPIT AFTER TAKEOFF.  THE SMOKE APPEARED TO COME FROM THE TAT GUAGE.  THE AIRCRAFT WAS RETURNED TO ATL WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE TAT INDICATOR AT FAULT.  THE INDICATOR WAS REMOVED AND REPLACED.  THE TAT CIRCUIT BREAKER WAS REPLACED AS A PRECAUTIONARY MEASURE.  TAT INDICATION TESTED NORMAL.  ALL WIRING FOR TAT INDICATOR AND BREAKER WAS INSPECTED AND NO DEFECTS WERE FOUND.
