Narrative:

Inbound from lvl VOR to ric VOR, we were cleared to 2000 ft and direct jesty (ric ILS runway 2 FAF). ATC was also working air carrier Y. Their location was west of ric, cleared to 3000 ft. Ric approach asked if we had air carrier Y in sight. We had a cloud layer to descend through, bases at 4000 ft MSL. Air carrier Y had us in sight first and was cleared for a visual to ric runway 34. ATC asked again if we had air carrier Y in sight. We did, and told them so. It was a few more seconds before we had runway 2 in sight. At that point, ATC cleared us for a visual approach. Separation with air carrier Y at this point was about 8 mi to our left front horizontal, 1000 ft vertical. As I kept an eye on air carrier Y, we started to configure the aircraft to flaps 2 degrees and 180 KTS. Being air carrier Y had to cross our final, my expectation was for him to maintain 3000 ft until passing the runway 2 centerline on his way to runway 34. We did not notice that he descended until I saw on TCASII he was 200 ft above and about 1 1/2 - 2 mi to our left on a collision. He was still descending. At this point we still had not received a TCASII warning. We started evasive action by climbing to 2500 ft. I lost sight of air carrier Y as he went under our nose. At this point I thought I heard a TA, but can't be 100% sure. We all have responsibilities during a visual approach. Both crew and ATC even though they let us loose. With 2 aircraft not following each other, vertical separation must be maintained until diverging from each other. When air carrier Y started his descent before passing our path he broke vertical separation and our expectation of his action. ATC should also have seen that there was a collision course. They (ATC) had separation when we both accepted the visual approach, still has a moral responsibility to monitor the situation. Last, why didn't air carrier Y nor ourselves receive an RA on TCASII?

Title: WHILE ON A VISUAL APCH TO RWY 2, THE A319 CREW OBSERVED A CONVERGING DC9 ON THE L SIDE DSNDING FOR AN APCH TO RWY 34 RESULTING IN AN NMAC.

Narrative: INBOUND FROM LVL VOR TO RIC VOR, WE WERE CLRED TO 2000 FT AND DIRECT JESTY (RIC ILS RWY 2 FAF). ATC WAS ALSO WORKING ACR Y. THEIR LOCATION WAS W OF RIC, CLRED TO 3000 FT. RIC APCH ASKED IF WE HAD ACR Y IN SIGHT. WE HAD A CLOUD LAYER TO DSND THROUGH, BASES AT 4000 FT MSL. ACR Y HAD US IN SIGHT FIRST AND WAS CLRED FOR A VISUAL TO RIC RWY 34. ATC ASKED AGAIN IF WE HAD ACR Y IN SIGHT. WE DID, AND TOLD THEM SO. IT WAS A FEW MORE SECONDS BEFORE WE HAD RWY 2 IN SIGHT. AT THAT POINT, ATC CLRED US FOR A VISUAL APCH. SEPARATION WITH ACR Y AT THIS POINT WAS ABOUT 8 MI TO OUR L FRONT HORIZ, 1000 FT VERT. AS I KEPT AN EYE ON ACR Y, WE STARTED TO CONFIGURE THE ACFT TO FLAPS 2 DEGS AND 180 KTS. BEING ACR Y HAD TO CROSS OUR FINAL, MY EXPECTATION WAS FOR HIM TO MAINTAIN 3000 FT UNTIL PASSING THE RWY 2 CTRLINE ON HIS WAY TO RWY 34. WE DID NOT NOTICE THAT HE DSNDED UNTIL I SAW ON TCASII HE WAS 200 FT ABOVE AND ABOUT 1 1/2 - 2 MI TO OUR L ON A COLLISION. HE WAS STILL DSNDING. AT THIS POINT WE STILL HAD NOT RECEIVED A TCASII WARNING. WE STARTED EVASIVE ACTION BY CLBING TO 2500 FT. I LOST SIGHT OF ACR Y AS HE WENT UNDER OUR NOSE. AT THIS POINT I THOUGHT I HEARD A TA, BUT CAN'T BE 100% SURE. WE ALL HAVE RESPONSIBILITIES DURING A VISUAL APCH. BOTH CREW AND ATC EVEN THOUGH THEY LET US LOOSE. WITH 2 ACFT NOT FOLLOWING EACH OTHER, VERT SEPARATION MUST BE MAINTAINED UNTIL DIVERGING FROM EACH OTHER. WHEN ACR Y STARTED HIS DSCNT BEFORE PASSING OUR PATH HE BROKE VERT SEPARATION AND OUR EXPECTATION OF HIS ACTION. ATC SHOULD ALSO HAVE SEEN THAT THERE WAS A COLLISION COURSE. THEY (ATC) HAD SEPARATION WHEN WE BOTH ACCEPTED THE VISUAL APCH, STILL HAS A MORAL RESPONSIBILITY TO MONITOR THE SIT. LAST, WHY DIDN'T ACR Y NOR OURSELVES RECEIVE AN RA ON TCASII?
