## Discrepancy

ON FINAL APPROACH STARTED TO GET A STRONG BURNING ODOR THEN STARTED TO GET SMOKE COMING OUT OF THE VENTS IN THE FLIGHT DECK.  TURNED OFF THE LEFT PACK AND THE SMOKE AND ODOR STOPPED.  CALLED THE FLIGHT ATTENDANTS TO ASK WHAT THEY SAW AND SMELLED.  THEY COULD SMELL THE BURNING ODOR BUT DID NOT SEE ANY SMOKE.   (FLIGHT 6408) TROUBLE SHOT COCKPIT SMOKE EVENT IN REFERENCE TO FIM 21-21-00.  CONFIRMED LEFT ACM TO BE FROZEN. DUPLICATED PILOT WRITE UP, RAN LEFT ENGINE PER AMM 71-00-00. LEFT ENGINE BLEED TO RIGHT PACK NO SMOKE IN COCKPIT.
