## Discrepancy

DURING CRUISE, THE RT ENGINE BEGAN TO LOSE POWER.  THE RT ENGINE STARTED TO BYPASS FUEL LOWER THAN NORMAL EGT TEMPERATURE. REDUCED POWER AND THE AFFECTED ENGINE QUIT BYPASSING. APPLIED POWER, & RT ENGINE EGT INCREASED AND THE ENGINE BYPASSED AGAIN.  FOLLOWED QRH AND WAS UNABLE TO RESOLVE THE ISSUE.  DECLARED AN EMERGENCY, PERFORMED A PRECAUTIONARY IN FLIGHT RT ENG SHUTDOWN, DIVERTED, AND LANDED WITHOUT INCIDENT.  INSPECTED THE RT ENGINE & PERFORMED GROUND RUNS. THE FUEL BYPASS DISCREPANCY COULD NOT BE DUPLICATED.  MAINTENANCE REMOVED AND REPLACED THE RIGHT TEMP LIMITER. PERFORMED RT ENGINE GROUND RUNS,  OPS OF THE RIGHT ENGINE BY-PASS CIRCUIT WAS NORMAL. THE AIRCRAFT WAS RETURNED TO SERVICE.
