## Discrepancy

CREW OBSERVED THE RT ENGINE ITT INDICATION SPIKE ABOVE ALLOWED MARGIN.  PERFORMED ENGINE SHUTDOWN.  RESTART PERFORMED AND ENGINE PERFORMED NORMAL FOR DURATION OF FLIGHT.  MAINTENANCE DOWNLOADED THE DEEC'S AND DATA SHOWED NORMAL FOR BOTH ENGINES.  DAU UNITS WERE SWAPPED AND ENGINE RUNS PERFORMED WITH NO DEFECTS NOTED.  PER THE TFE 731 LMM THE ENGINE RUNS SHEETS PROVED THE ENGINE OPERATING UNDER NORMAL PARAMETERS.  AIRCRAFT RETURNED TO SERVICE AND WILL BE MONITORED FOR FURTHER OCCURANCE.  THIS DATA HAS BEEN FORWARDED TO LEARJET ENGINEERING VIA THE JSLLC CAS REPORTING SYSTEM.
