## Discrepancy

THE PILOT AND MEDICAL CREW BOTH REPORTED SEEING AND SMELLING SMOKE IN THE COCKPIT DIRECTLY AFTER TAKEOFF. THE PILOT THEN CYCLED THE DEMISTER/HEATER VALVES WITH NO CHANGE.  HE THEN MADE AN UNSCHEDULED LANDING.  MX WAS NOTIFIED AND RESPONDED IMMEDIATELY.  THE MECHANIC PERFORMED A VISUAL INSP WITH NO DEFECTS NOTED.  HE THEN HAD THE PILOT PERFORM A GROUND RUN AND CYCLED ALL THE DEMISTER AND HEATING KNOBS SEVERAL TIMES WITH NO DEFECTS.  THE ACFT WAS RETURNED TO SERVICE AT THAT TIME.
