## Discrepancy

(CAN) IN FLIGHT, THE PILOT NOTICED THAT THE LT ENGINE CYLINCER TEMPERATURE WAS ABNORMALLY HIGH.  ALL OTHER PARAMETERS WERE IN THE GREEN.  THE PILOT ASKED FOR A PRIORITY LANDING.  WE DISCOVERED THAT THE WIRING FOR THE CHT PROBE WAS CUT. THE TERMINAL WAS REPLACED, EVERYTHING BACK TO NORMAL.
