## Discrepancy

DURING CLIMBOUT, LT TAIL PIPE OVERHEAT LIGHT ILLUMINATED.  RETURNED TO AIRPORT, LANDING WAS UNEVENTFUL.  FURTHER INVESTIGATION DID NOT REVEAL ANY PHYSCIAL OR ELECTRICAL PROBLEMS WITH THE TAIL PIPE HEAT DETECTION SYSTEM.  AS A PRECAUTIONARY MEASURE ALL THREE OVERHEAT PROBES WERE CHANGED.  NO FURTHER PROBLEMS WERE NOTED.
