## Discrepancy

ENROUTE, THE CREW RECEIVED A RGB CHIP DETECT BLUE CAS MESSAGE.  THE CREW WAS THEN INSTRUCTED TO DIVERT TO PIT AND LANDED WITH NO FURTHER DISCREPENCIES.  MAINTENANCE THEN INSPECTED AND FOUND A HAIR LIE PARTICLE AND A FLAKE ON THE RGB CHIP DETECTOR, ALL WITHIN PRESCRIBED LIMITS.  MAINTENANCE REPLACED THE FILTERS, CLEANED THE CHIP DETECTORS, AND CANNON PLUGS IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 79-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
