Shortly after takeoff from the Charleston International Airport, the crew experienced smoke in the cockpit. The flight diverted to Raleigh Durham International Airport, and landed without further incident. Maintenance personnel found heat damage that centered around the left utility bus electrical relay. The laboratory's examination revealed that all of the thermal damage, melting, charring and arcing, evidence showed that thermal event originated internally or on an external relay terminal. The source of the smoke was found to be the failure of a Hartman electrical relay.
Probable Cause: The failure of a utility bus relay which resulted in an electrical fire and subsequent smoke in the cockpit.
