## Discrepancy

NR 1 ENGINE COMPRESSOR STALLED 4 TIMES CLIMBING THROUGH 15,500 FT.  AFTER COMPRESSOR STALL, WITH SAME THROTTLE ANGLE, NR 1 ENG N1 WAS 98.4 PERCENT WHILE NR 2 WAS 104 PERCENT.  ALL OTHER PRIMARY ENGINE PARAMETERS WERE FLUCTUATING.  WHEN THE NR 1 THRUST LEVER WAS RETARDED TO FLT IDLE THE COMPRESSOR STALL CEASED AND NORMAL FLIGHT IDLE PARAMETERS WERE NOTED.  AIRCRAFT LANDED WITHOUT INCIDENT.
