## Discrepancy

DURING APPROACH INTO ATL FROM TLH, THE CREW NOTICED AN UNUSUAL ODOR IN THE CABIN WHEN SWITCHING FROM THE ENGINE BLEEDS TO THE AUXILIARY POWER UNIT.  THE AIRCRAFT LANDED SAFELY IN ATL.  MAINTENANCE REMOVED AND REPLACED THE RIGHT AND LEFT COALESCER BAGS ON THE WATER SEPARATOR ASSEMBLY.  OPS CHECKS GOOD.  AIRCRAFT OK FOR SERVICE.  (M)
