## Discrepancy

AFTER TAKEOFF, NR 1 ENGINE SURGED AND PASSENGERS REPORTED FLAMES COMING FROM TAILPIPE.  EGT WAS 900 DEGREES.  ENGINE SHUT DOWN  AND AIRCRAFT RETURNED TO FIELD.  SHUTDOWN CAUSED BY COMPRESSOR STALL DUE TO COMPRESSOR BLADE FAILURE.  BLADE FAILURE WAS CAUSED BY AN OUT OF SCHEDULE VARIABLE STATOR VANE-LEVER ARM WAS DISENGAGED FROM THE ACTUATING RING.  REPLACED ENGINE.  OPS CHECK GOOD.
