## Discrepancy

AFTER DEPARTURE, THE WHOLE CREW SMELLED A RUBBER & ELEC BURN TYPE SMELL.  THE PILOT ISOLATED THE SMELL TO THE AIR CONDITIONER & TURNED OFF THE AIR CONDITIONER SYS & THE SMELL WENT AWAY.  WE CONTINUED THE FLIGHT BACK TO THE BASE WITH NO OTHER INCIDENTS & COMPLETED A NORMAL SHUTDOWN & CALLED THE MECHANIC.  IT WAS DISCOVERED THAT THE AIR CONDITIONER CLUTCH WAS LOCKED DOWN & THE BELT WAS CAUSING THE BURNING SMELL.  THE MECHANIC CUT THE BELT OFF.  MELED THE AIR CONDITIONER & PLACED THE ACFT BACK IN SERVICE.
