Narrative:
On five mile final at about 500 ft AGL the aircraft experienced a loss of system hydraulic B. The pilot flying reported that the aircraft had a tendency to roll right and that we were going around. The flaps remained at 40 due to the failed system B. We declared an emergency with tower and entered a left downwind for runway xxl. We completed the loss of system B QRH on downwind. We decided to leave the flaps at 40 and landed uneventfully. We were met by emergency crews who reported a leak outboard of the second pylon on the right wing. We shutdown #2 engine and taxied uneventfully to the gate. Maintenance is troubleshooting at this time. We do not know the cause.
