## Discrepancy

AT TOP OF DESCENT, THE NR 2 ENGINE EXPERIENCED COMPRESSOR STALL.  THE EGT ROSE TO 800 DEGREES AND BACK TO NORMAL WITHIN A MINUTE.  ALSO, WITH LOW FUEL FLOW N1 AND N2 WOULD NOT RESPOND TO THROTTLE MOVEMENTS.  CREW FOLLOWED COCKPIT OPERATING MANUAL AND CONTINUED FLIGHT TO MSP.  VISUAL AND BORESCOPE INSPECTION OF NR 2 ENGINE 6, 7 AND 15TH HPC, 13TH STAGE STATOR WERE NORMAL.  REPLACED BLEED VALVE, PRESSURE CONTROL AND EGT INDICATOR.
