## Discrepancy

DURING FLIGHT, AFTER A SERIES OF BUMPS OR WHAT SOUNDED LIKE A BACKFIRE. NR 2 ENGINE ITT SPIKED INTO THE RED FOLLOWED BY NR 2 ENGINE OUT.  RESTART WAS SUCCESSFUL, FOLLOWED SHORTLY BY REPEAT OF UNCOMMANDED ENGINE SHUTDOWN.  THE ACFT LANDED WITHOUT FURTHER INCIDENT. MAINTENANCE INSPECTED AND REPLACED THE NR 2 ENGINE.  OPS CHECKED GOOD.  DURING TEARDOWN FOUND THE BOLT THAT ATTACHES THE CVG ACTUATOR TO THE TORQUE TUBE WAS SHEARED OFF.
