## Discrepancy

IAH TO CMH - DURING CLIMB, THE CREW RECEIVED A HYDRAULIC SYSTEM 2 FAIL MESSAGE THEN CONFIRMED THAT THE SYSTEM 2 QUANTITY WAS ZERO.  THE AIRCRAFT RETURNED TO FIELD AT IAH AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED THE HYDRAULIC SYSTEM AND FOUND A HAIRLINE CRACK ON THE HYDRAULIC TUBE FROM THE BACK OF THE SERVICING PORT.  AFTER CHANGING THE TUBE AND SERVICING THE HYDRAULICS, THE NR 2 SYSTEM OPERATED NORMALLY.
