## Discrepancy

IMMEDIATELY AFTER TAKEOFF WE HAD SMOKE IN THE COCKPIT. WHEN PACKS WERE SHUTOFF SMOKE STOPPED. AFTER TRANSFERING BLEED AIR TO ENGINES AND TURNING PACKS BACK ON THERE WAS NO MORE SMOKE. WE HAD BEEN DEICED JUST PRIOR TO TAKING OFF WITH TYPE I AND TYPEIV FLUID. CORRECTIVE ACTION: REMOVED AND REPLACED LEFT AND RIGHT ACM COOLING TURBINES IAW CH-650 AMM 21-51-16. REINSTALLED WATER SEPERATORS PER CH-650 AMM 21-51-13. PERFORMED LEAK CHECK AND OPERATIONAL / TEST, NO DEFECTS NOTED.
