## Discrepancy

EN ROUTE CLT TO TOL, WHEN THE NR 4 TURBO COMPRESSOR WAS TURNED ON,  A LOUD HOWL WAS HEARD AND RPM STARTED TO FLUCTUATE.  THE T/C RPM THEN WENT TO ZERO VERY RAPIDLY, THE T/C WAS SECURED.  AN ACRID SMELL WAS SENSED IN THE COCKPIT AS THE T/C RPM DROPPED TO ZERO.  MAINTENANCE DEFERRED THE TURBO COMPRESSOR IN ACCORDANCE WITH THE DC-8 MEL AND RETURNED THE AIRCRAFT TO SERVICE.
