## Discrepancy

IN FLIGHT, THE PILOT NOTICED THE ENGINE CHIP LIGHT ILLUMINATE.  LANDED AND THE ENGINEER LOOKED AT THE CHIP DETECTORS AND NO METAL WAS FOUND.  THEN RE INSTALLED THE CHIP DETECTORS AND CARRIED OUT A GROUND RUN.  AFTER 10 MINUTES OF GROUND RUNNING ANOTHER CHIP LIGHT OCCURRED.  AFTER THE ENGINE COOLED OFF THE CHIP LIGHT WOULD GO OUT.   THE ELECTRICALLY OPERATED CHIP DETECTOR WAS FOUND TO CAUSE A LIGHT WHEN HOT AND THEM EXTINGUISH WHEN COOLED OFF.
