## Discrepancy

AFTER TAKEOFF ACFT HAD SOME SMOKE IN THE COCKPIT FROM THE OVERHEAD PANEL, THE PILOTS SHUTOFF ALL THE SWITCHES TO THE PANEL AND THE SMOKE STOPPED THEY THEN RETURNED TO BASE AND LANDED WITHOUT INCIDENT.  THE OVERHEAD PANEL WAS REMOVED AND WIRING INSPECTED,  WE FOUND THE RT PITOT HEAT SHUNT WAS SHORTED ONTO AN ADEL CLAMP SECURING A ENVIRONMENTAL TUBE. THE CLAMP WAS REPOSITIONED TO PROVIDE ADEQUATE CLEARANCE FROM THE SHUNT AND ACFT RETURNED TO SERVICE. ALL OTHER ACFT ARE IN THE PROCESS OF BEING INSPECTED.
