## Discrepancy

FLIGHT 3884, SYRACUSE TO PHILADELPHIA, HAD TO DIVERT TO AVOCA DUE TO ODOR IN THE CABIN AND COCKPIT.  MAINTENANCE INVESTIGATED AND REMOVED AND REPLACED THE AIR CYCLE MACHINE AND THE NR 2 AIR SWITCHING VALVE.  PROBLEM STILL EXISTED.  AIRCRAFT WAS FERRIED TO MIDDLETOWN FOR REMOVAL AND REPLACEMENT OF THE RIGHT HAND ENGINE.
