## Discrepancy

PILOT REPORTED SMOKE IN COCKPIT JUST PRIOR TO LANDING.  AIRCRAFT LANDED WITHOUT HAVING TO DECLARE AN EMERGENCY.  MAINTENANCE FOUND RELAY K30 IN THE TAS PROBE HEAT CIRCUIT HAD OVERHEATED DUE TO A FAILED CONNECTION ON THE POWER FEED TO THE PROBE HEATER.  RELAY K30 AND K25 AND K11 WERE REPLACED.  K25 AND K11 WERE REPLACED FOR PERCAUTIONARY REASONS DUE TO THE HEAT DAMGE FROM RELAY K30.
