## Discrepancy

FLIGHT LEVEL 330, FLIGHT CREW NOTED AN ACRID ODOR IN COCKPIT THAT THEN TRAVELED BACK TOWARDS THE MID CABIN.  ODOR DISSIPATED AND NEVER RETURNED.  FLIGHT UNEVENTFULLY LANDED AT DESTINATION.  ON INSPECTION, MAINTENANCE FOUND THE ACM HAD SEIZED.  MAINTENANCE REPLACED THE ACM AND CLAMP, PERFORMED A SUCCESSFUL LEAK CHECK AND RETURNED THE AIRCRAFT TO SERVICE.
