## Discrepancy

CLE - FLT 2135 - THE CREW REPORTED A NR 2 ENGINE UNCOMMANDED SHUTDOWN IN FLIGHT.  ENGINE WOULD NOT RESTART AND THE AIRCRAFT DIVERTED INTO CVG AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE INSPECTED AND REPLACED THE NR 2 ENGINE.  OPERATIONAL CHECKS WERE GOOD.  TEAR DOWN REPORT FROM ROLLS ROYCE INDICATES THE FAILURE OF THE NR 2 ENGINE WAS DUE TO FRACTURE OF THE 1ST STAGE COMPRESSOR BLADE.  FRACTURE INITIATED AT LEADING EDGE 0.6 INCH ABOVE DOVETAIL CORROSION WAS PRESENT AT FRACTURE ORIGIN AND ON SEVERAL OTHER BLADES.
