## Discrepancy

ALB FLT 2983 - THE CREW REPORTED SMOKE HAZE IN THE COCKPIT SHORTLY AFTER TAKEOFF THEN DISSIPATED.  ALSO REPORTED A LAV SMOKE WARNING MSG ON THE EICAS FOR ABOUT A MINUTE.  MAINTENANCE INSPECTED AND REPLACED THE NR 1 ENGINE.  THE TEAR DOWN REPORT FROM ROLLS ROYCE INDICATED THE PRIMARY CAUSE OF SMOKE/HAZE IN THE COCKPIT WAS THE NR 4 CARBON SEAL.  THE ENGINE WAS REPAIRED TO SERVICEABLE CONDITION.
