## Discrepancy

EN ROUTE FROM CLT TO ORL, APPROXIMATELY 90 MINUTES INTO THE FLIGHT THE RIGHT ENGINE STARTED BACKFIRING.  THE PILOT PROCEEDED TO SHUT THE ENGINE DOWN AS A PRECAUTIONARY MEASURE AND DIVERTED TO SGJ AND LANDED SAFELY WITHOUT INCIDENT.  MAINTENANCE INSPECTED AND FOUND ALL FOUR CYLINDER BASE MOUNTING STUDS ON RIGHT ENGINE NR 6 CYLINDER BROKEN.  MAINTENANCE IS IN PROCESS OF REPAIRING ENGINE.
