## Discrepancy

DURING FINAL APPROACH FROM AVL-ATL, THE FLIGHT ATTENDANT NOTICED A MIST AND UNUSUAL SMELL IN THE CABIN.  THE CREW ALSO NOTICED A FAINT OIL ODOR IN THE COCKPIT.  THE AIRCRAFT LANDED SAFELY IN ATL.  MAINTENANCE REMOVED AND REPLACED THE RT PACK TURBO FAN PRESSURE AND HEAR EXCHANGER OVERTEMP SWITCHES.  OPERATIONAL CHECKS GOOD AND AIRCRAFT OK FOR SERVICE.  (M)
