## Discrepancy

DURING START UP THE PILOT NOTED A HIGH RISE IN TEMP WHICH EXCEEDED ALLOWABLE TEMP FOR START.  IMMEDIATELY SHUT THE ENGINE DOWN.  CONTACTED MX.  PER THE MX MANUAL NO TEMPS WERE EXCEEDED PER THE MX MANUAL ONLY THE "ALLOWABLE" LIMIT FOR PILOT START.  FURTHER TROUBLESHOOTING FOUND A FAULTY TEMP PROBE WHICH WOULD HAVE CAUSED A HIGHER THAN NORMAL TEMP DURING THE START.  CHANGED THE TEMP PROBE AND ENGINE STARTED NORMAL.
