## Discrepancy

AIRCRAFT DIVERTED FOR UNCONTROLLABLE HEAT, WITH VISIBLE SMOKE IN COCKPIT.  THE COCKPIT TEMP CONTROL VALVE WAS REPLACED.  IT WAS ALSO NOTICED THAT THE TEMP CONTROL VALVE LINES WERE SWAPPED.  LINES WERE ALSO INSTALLED IN CORRECT POSITION.  OPS CHECKS WERE GOOD AND THE AIRCRAFT RETURNED TO SERVICE.
