## Discrepancy

A FEW SECONDS LATER THE LEFT BLEED AIR LIGHT CAME ON AND WOULD NOT EXITNGUISH.  SMOKE BEGAN TO FILL THE COCKPIT FROM THE CENTER CONSOLE.  AIRCREW TURNED OFF THE LT FLOW PACK.  SMELL AND SMOKE CLEARED THE COCKPIT.  IN FLT EMERGENCY WAS DECLARED.  EMERGENCY PROCEDURES WERE USED.  A/C RETURNED TO LEX WITH NO OTHER PROBLEMS.  MX CREW WAS DEPLOYED FROM CLT TO LEX.  MX FOUND THE TEMP CONTROL VALVE STUCK IN THE OPEN POSITION.  LT BLEED AIR DEACTIVATED AND DEFERRED TOMSL NR 01998-03C.  A/C RETURNED TO CLT FOR REPAIR.
