## Discrepancy

(CAN) DURING A TRAINING FLIGHT A CAS WARNING MESSAGE INDICATING AN ENGINE FIRE WAS DISPLAYED.   THE ENGINE WAS SHUT DOWN AS A PRECAUTION AND THE A/C RETURNED TO BASE WITH OUT FURTHER INCIDENT.     DURING SUBSEQUENT TROUBLE SHOOTING IT WAS DETERMINED THAT WHEN THE TERMINAL ON THE 300 DEGREE SENSOR CAME INTO CONTACT WITH SUFFICIENT MOISTURE, A SHORT WOULD OCCUR THUS GENERATING THE CAS WARNING MESSAGE.  VIKING ISSUED SB V6/0017 TO APPLY SEALANT TO THE SENSOR TERMINAL PLATES.   VIKING WILL CONTINUE TO INVESTIGATE FURTHER.
