## Discrepancy

THE FLIGHT CREW REPORTED THAT THE RIGHT ENGINE OIL TEMP INDICATOR WAS SHOWING ERRATIC READINGS, SPIKES IN THE RED THEN BACK TO NORMAL AND CONTINUOUSLY REPEATING. THE BASE MAINTENANCE TEAM DETERMINED THE OIL TEMPERATURE SENSOR WAS DEFECTIVE. THE DEFECTIVE SENSOR WAS REMOVED, AND A NEW SENSOR WAS INSTALLED. OPERATIONAL / LEAK CHECKS WERE SATISFACTORY. THE AIRCRAFT WAS RETURNED TO SERVICE.
