## Discrepancy

WHITE SMOKE FILLED CABIN FROM BACK.  OBSERVER SAID IT WAS NOT COMING FROM EQUIPMENT RACKS.  SMELLED LIKE BURNING WOOD OR PAPER .  FIRE DEPARTMENT FOUND NO UNUSUAL HOT SPOTS.  RUNWAY 18R WAS CLOSED FOR APPROX 20 MIN WHILE FIRE DEPARTMENT INVESTIGATED.  AIRCRAFT WAS THEN TAXIED WITHOUT INCIDENT.  FOUND K3 CONDENSER BLOWER RELAY (PN MS24166D1)  BURNED.  REPLACED BLOWER RELAY AND TRANSORB DIODE.
