Narrative:

Scheduled flight. Positive control with richmond approach control. Being vectored for a visual to runway 2 at ric. Level flight 5000 ft and 210 KTS assigned. First officer flying the aircraft. Out TCASII on 10 mi range and below TA/RA. A target appeared at about 1:30 bearing at 800 ft above showing a descent. The bearing remained constant and the target descent continued. The first officer said 'we're going to have a conflict.' at about 5-6 mi we received a (TA). We started a descent. At about 4-5 mi the (RA) descend-descend command alarmed and 1200-1500 ft descend was commanded. Almost immediately after the start of the descent I (captain) acquired a visual on the conflict aircraft. A twin engine turboprop. Our descent went to 4400 ft. The conflict aircraft passed above and slightly behind our aircraft. Following sequence of events occurred. I informed ric approach controller that we had a near miss and asked 'do you want us to climb back to 5000 ft?' he said 'no, I'll now vector you for visual to runway 34.' on the ground I called (telephone) ric approach and talked with supervisor mr X. X was aware of the conflict. X said he was observing control at the time. X said the controller believed the assigned vectors would place us behind the light transport but that the light transport had slowed down. X asked if I wanted him to submit an incident report. I said 'do what you must, but I'm submitting a NASA and a TCASII report. I called company violations desk and talked with mr Z. I explained the incident and requested alpa assistance.

Narrative: SCHEDULED FLT. POSITIVE CTL WITH RICHMOND APCH CTL. BEING VECTORED FOR A VISUAL TO RWY 2 AT RIC. LEVEL FLT 5000 FT AND 210 KTS ASSIGNED. FO FLYING THE ACFT. OUT TCASII ON 10 MI RANGE AND BELOW TA/RA. A TARGET APPEARED AT ABOUT 1:30 BEARING AT 800 FT ABOVE SHOWING A DSCNT. THE BEARING REMAINED CONSTANT AND THE TARGET DSCNT CONTINUED. THE FO SAID 'WE'RE GOING TO HAVE A CONFLICT.' AT ABOUT 5-6 MI WE RECEIVED A (TA). WE STARTED A DSCNT. AT ABOUT 4-5 MI THE (RA) DSND-DSND COMMAND ALARMED AND 1200-1500 FT DSND WAS COMMANDED. ALMOST IMMEDIATELY AFTER THE START OF THE DSCNT I (CAPT) ACQUIRED A VISUAL ON THE CONFLICT ACFT. A TWIN ENG TURBOPROP. OUR DSCNT WENT TO 4400 FT. THE CONFLICT ACFT PASSED ABOVE AND SLIGHTLY BEHIND OUR ACFT. FOLLOWING SEQUENCE OF EVENTS OCCURRED. I INFORMED RIC APCH CTLR THAT WE HAD A NEAR MISS AND ASKED 'DO YOU WANT US TO CLB BACK TO 5000 FT?' HE SAID 'NO, I'LL NOW VECTOR YOU FOR VISUAL TO RWY 34.' ON THE GND I CALLED (TELEPHONE) RIC APCH AND TALKED WITH SUPVR MR X. X WAS AWARE OF THE CONFLICT. X SAID HE WAS OBSERVING CTL AT THE TIME.
