## Discrepancy

ON CLIMBOUT, THE CREW RECEIVED AN ON SIDE BLUE STICK SHAKER CAS MESSAGE.  THE AIRCRAFT THEN RETURNED TO PIT AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED, REMOVED, AND REPLACED THE NR 2 DATA ACQUISITION UNIT IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 34-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
