## Discrepancy

CAPTAIN REPORTED SMOKE ON AFT LAVATORIES. AT PLATFORM, MAINTENANCE PERSONNEL PERFORMED A TURBINE COOLING SYSTEM CHECK, DETERMINING TO REPLACE THE WATER SEPARATOR OF LT AIR CONDITIONING SYSTEM IAW MM 21-20-01; SO AIRCRAFT WAS SENT TO THE HANGAR AND DURING OVERNIGHT CHECK, THE HEAT EXCHANGERS OF BOTH AIR CONDITIONING SYSTEMS AND COOLING TURBINE WERE CHECKED, ALL CORRECT. APU WAS REPLACED IAW 49-10-00; DUCTS OF BOTH AIR CONDITIONING SYSTEM WERE CLEANED IAW MPCM 21-30-00 AND WATER SEPARATORS WERE REPLACED IAW MM 21-20-02, TESTED CORRECT IAW MM 21-00-00.
