## Discrepancy

AFTER DEPARTURE, THE FLT ATTENDANT REPORTED SMOKE IN THE CABIN.  THE SMOKE CLEARED WHEN THE LT PACK WAS SECURED.  AN EMERGENCY WAS DECLARED AND THE FLT RETURNED TO A NORMAL SAFE LANDING BACK AT DTW.  NO FIRE OR IMMEDIATE SOURCE OF SMOKE WAS FOUND.  MAINTENANCE FOUND BOTH OF THE WATER SEPARATOR SOCKS TO BE OILY AND REPLACED THEM. THE LEFT HAND ACM WAS ALSO REPLACED DUE TO HIGH TIME. THE AIRCRAFT RETURNED TO SERVICE ON 26AUG AND HAS NOT EXPERIENCED ANY REPEAT SYSTEM PROBLEMS.
