## Discrepancy

SEA - FLIGHT 2119 - DURING CRUISE FLIGHT, THE CREW RECEIVED A MASTER WARNING WITH ASSOCIATED SMOKE WARNING LIGHT.  THIS OCCURRED TWICE DURING FLIGHT, HOWEVER, THE FLIGHT ATTENDANTS DID NOT OBSERVE, OR SMELL, ANY SMOKE.  MAINTENANCE INSPECTED THE AIRCRAFT AND THE NR 1 AND NR 2 CARGO SMOKE DETECTORS.  DUST WAS OBSERVED ON BOTH.  THE DETECTORS WERE CLEANED AND OPERATIONAL CHECKS WERE PERFORMED.  THE CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
