## Discrepancy

(CAN) AFTER IN FLIGHT TEST OF ACFT ADG MX NOTICED AN AUDIBLE HISS COMING FROM THE CREW OXYGEN SERVICE POINT.  UPON FURTHER INVESTIGATION IT WAS DISCOVERED THAT THE CAPILARY LINE (P/N S7047-7) OFF THE BACK OF THE CREW OXYGEN SERVICE POINT GAUGE WAS FRACTURED AT THE FWD BULKHEAD END OF THE LINE.  SUSPECT VIBRATION FROM THE OPERATION OF THE ADG CAUSED THE LINE TO FRACTURE.
