## Discrepancy

SJT - FLT 3588 - DURING APPROACH, CREW NOTICED A BURNING SMELL THROUGHOUT THE AIRCRAFT.  SHUT DOWN THE RIGHT BLEED AND THE SMELL WENT AWAY.  MAINTENANCE INSPECTED BLEED SYSTEM, THE REST OF THE AIRCRAFT, AND PERFORMED ENGINE RUNS, BUT COULD NOT DUPLICATE THE SMELL.  OPENED MEL AGAINST THE RIGHT ACM AND SUBSEQUENTLY.  REMOVED AND REPLACED THE ACM, CLEARED THE MEL, AND RETURNED THE AIRCRAFT TO SERVICE.  (M)
