## Discrepancy

FLIGHT 1868, PBI-CLT - ON TAKEOFF AND LANDING THE CREW REPORTED A SOUR ODOR COMING FORM THE AIR CONDITIONING PACKS.  THE ODOR DISSIPATED IN CLIMB.  MAINTENANCE INSPECTED THE LEFT AND RIGHT RAM INLET, THE LEFT AND RIGHT ENGINE INLETS AND AIR MIX CHAMBER.  ALL CHECK OKAY.  MAINTENANCE RAN THE ENGINES ONE AT A TIME WITH EACH SIDE PACK FOR FIVE MINUTES EACH.  NO FURTHER ODORS NOTED.
