## Discrepancy

WHILE FLYING BETWEEN EW921 AND SS246, SAW THE NR 1 ENGINE TEMPERATURE IN THE RED.  REDUCED POWER TO OEI LEVELS AND LOOKED FOR SECONDARY INDICATIONS AND SAW NONE.  CONSULTED CHECKLIST AND PERFORMED A SINGLE ENGINE SHUTDOWN.  CONTACTED COM CENTER AND WAS ADVISED TO TAKE ACFT.  LANDING WAS UNEVENTFUL.  MAINTENANCE REPLACED THE NR 1 ENGINE OIL TEMP BYPASS VALVE.
