## Discrepancy

AFTER TAKEOFF FROM WDG, THE CREW GOT A CHIP LIGHT ON THE RIGHT ENGINE.  THE CAPTAIN DECIDED TO RETURN TO WDG AND MAKE A PRECAUTIONARY SHUTDOWN OF THE RIGHT ENGINE.  DURING THE PRE-SHUTDOWN CHECKS, THE ENGINE FLAMED OUT.  THE CREW THEN MADE A LANDING AT WDG WITH NO FURTHER INCIDENT.  ON INSPECTION, IT WAS FOUND THAT ACCESSORY DRIVE GEAR ASSEMBLY, P/N 310601-6, S/N 3P17909, HAD FAILED AND THE IDLER GEAR ASSEMBLY, P/N 3101599-2, S/N 3P17792, HAD ALSO FAILED.  BOTH ASSEMBLIES WERE REPLACED AND THE AIRCRAFT WAS RETURNED TO SERVICE.  (M)
