## Discrepancy

THE NR 2 ENGINE GAVE OFF A LOUD BOOM AND THE AIRCRAFT SHUDDERED AND YAWED DURING CLIMBOUT OF ORD AT 8,000 FEET.  THE NR 2 ENGINE INDICATIONS WERE FROZEN.  QRH WAS FOLLOWED AND THE CREW SHUTDOWN THE ENGINE.  THE AIRCRAFT WAS RETURNED TO ORD WHERE IT LANDED WITHOUT INCIDENT.  INITIAL INSPECTION BY MAINTENANCE FOUND METAL IN THE ENGINE TAILPIPE.  THE NR 2 ENGINE WILL BE REMOVED AND REPLACED.  THE SDR WILL REMAIN OPEN FOR PART INFORMATION PENDING ENGINEERING INVESTIGATION.  ENGINEERING INVESTIGATION CONCLUDED THAT THE PRIMARY CAUSE OF ENGINE FAILURE WAS FAILURE OF THE LPT DUE TO A HOT START ON PREVIOUS ENGINE START.
