## Discrepancy

THE CREW REPORTED THAT THE VAPOR CYCLE AIR CONDITIONING WAS MAKING A LOUD NOISE, THEY OPENED THE BAGGAGE ACCESS TO INVESTIGATE & NOTED SMOKE COMING FROM THE AREA WHERE THE VAPOR CYCLE SYS IS INSTALLED.  THE MX DEPARTMENT OPERATED THE SYS & FOUND SPARKS & SMOKE EMANATING FROM THE ACFT COMPRESSOR DRIVE MOTOR.  THE DEFECTIVE MOTOR WAS REMOVED & AN OVERHAULED UNIT WAS INSTALLED, FT OK.
