## Discrepancy

FLT NR 149 - PHL - THE NR 1 ENG FAILED WHILE IN FLIGHT AT 31,000 FEET.  THE ENGINE INDICATIONS AFTER FAILURE WERE, EGT 800, N1 20 PERCENT, N2 49 PERCENT, AND OIL PRESSURE AT 8 PSI.  THE NR 1 ENGINE WAS SHUT DOWN AND THE AIRCRAFT WAS DIVERTED TO PHL WHERE IT LANDED WITHOUT INCIDENT.  THE NR 1 ENGINE WAS REMOVED AND REPLACED.  LEAK AND OPERATIONAL CHECKS WERE GOOD.  TEARDOWN REVEALED A C10 BLADE LOCK FRACTURE AS THE PRIMARY CAUSE OF THE ENGINE FAILURE.  (M)
