Narrative:

During approach to clt we were being vectored to land on runway 23 when an aircraft blew a tire and closed the runway. We were turned from a northeast heading to 360 degrees. As we rolled out of the turn we received an RA from our TCASII and saw a target at 2 O'clock and 2 mi. We looked out and saw a B757 at our altitude and converging. We rolled right and kept the traffic in sight. The reason I saw for this near midair collision was approach was traffic saturated, and was vectoring aircraft away from runway 23 to runway 18L. Because of this saturation the controller was overwhelmed and ended up putting 2 airplanes in the sky at the same point. If it were not for TCASII, I can say the results would have been devastating.

Title: OPERROR NMAC BTWN ACR A AND ACR B.

Narrative: DURING APCH TO CLT WE WERE BEING VECTORED TO LAND ON RWY 23 WHEN AN ACFT BLEW A TIRE AND CLOSED THE RWY. WE WERE TURNED FROM A NE HDG TO 360 DEGS. AS WE ROLLED OUT OF THE TURN WE RECEIVED AN RA FROM OUR TCASII AND SAW A TARGET AT 2 O'CLOCK AND 2 MI. WE LOOKED OUT AND SAW A B757 AT OUR ALT AND CONVERGING. WE ROLLED R AND KEPT THE TFC IN SIGHT. THE REASON I SAW FOR THIS NMAC WAS APCH WAS TFC SATURATED, AND WAS VECTORING ACFT AWAY FROM RWY 23 TO RWY 18L. BECAUSE OF THIS SATURATION THE CTLR WAS OVERWHELMED AND ENDED UP PUTTING 2 AIRPLANES IN THE SKY AT THE SAME POINT. IF IT WERE NOT FOR TCASII, I CAN SAY THE RESULTS WOULD HAVE BEEN DEVASTATING.
