## Discrepancy

THE NR 1 ENGINE GAVE OFF A LOUD BANG WITH VIBRATION AND YAW FELT WHILE EN ROUTE.  THE NR 1 ENGINE GAUGES BECAME ERRATIC.  THE N1 AND N2 EVENTUALLY STABILIZED.  THE AIRCRAFT WAS DIVERTED TO MSY WHERE IT LANDED WITHOUT INCIDENT.  THE NR 1 ENGINE WAS REMOVED AND REPLACED.   *S/D*  INVESTIGATION CONCLUDED THAT THE PRIMARY CAUSE OF ENGINE FAILURE WAS DUE TO A BROKEN C-4 BLADE.
