## Discrepancy

THE PILOT REPORTED AN ENGINE FIRE LIGHT ON ENGINE START.  AFTER SHUTDOWN, THE PILOT NOTIFIED THE MECHANIC WHO DETERMINED THAT THE FIRE DETECTOR THAT WAS MOUNTED TO THE M05 HAD A DIRTY CONNECTOR.  THE MECHANIC CLEANED THE CONNECTOR AND PERFORMED ANOTHER ENGINE RUN TO CHECK THE FIRE DETECTOR.  NO OTHER DEFECTS WERE FOUND, AND THE ACFT WAS RETURNED TO SERVICE.
