## Discrepancy

THE NR 2 ENGINE COMPRESSOR STALLED WHEN THE THRUST LEVERS WERE BROUGHT BACK TO IDLE AT TOP OF DECENT.  THE AIRCRAFT CONTINUED THE APPROACH AND LANDED UNEVENTFULLY.  MAINTENANCE REPLACED THE PRESSURE RATIO BLEED CONTROL VALVE (PRBC).   GROUND OPERATIONAL CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
