## Discrepancy

THE NR 1 ENGINE FAILED DURING STABLE CRUISE AT FL 380 WHILE ENROUTE.  THE HIGHEST EGT OBSERVED WAS 890 DEGREES AND N1 WENT TO 24 PERCENT.  THE AIRCRAFT WAS DIVERTED, WHERE IT LANDED WITHOUT INCIDENT.  THE ENGINE FAILURE WAS REPORTED TO BE AN UNCOMMANDED SHUTDOWN.  INITIAL ENGINE EXAMINATION FOUND MANY BLADES MISSING FROM FAN AND TURBINE WHEEL.  THE NR 1 ENGINE WAS REMOVED AND REPLACED.  THE SDR WILL REMAIN OPEN FOR PART INFO PENDING INVESTIGATION.  (K)
