TCASII RA.

Narrative

WHILE BEING VECTORED FOR A VISUAL APCH; WE WERE TOLD BY APCH CTL OF TFC THAT WOULD BE XING BEHIND US AND HAD US IN SIGHT. WE DID NOT HAVE THE TFC VISUALLY OR ON TCASII AT THAT TIME. AS I WAS DSNDING AND TURNING TOWARDS FINAL ONCE CLRED FOR THE VISUAL WE RECEIVED A RA AND A 'CLB' COMMAND. I STOPPED THE DSCNT AND BEGAN A CLB AS I CONTINUED WITH THE TURN. ON OUR TCASII DISPLAY THE RA WAS AT AN ALT OF 4800 FT MSL AND WE WERE CLBING THROUGH 5000 FT. APCH QUERIED THE SINGLE ENG CESSNA IF THEY STILL HAD VISUAL CONTACT WITH THE B-737. AFTER A SEVERAL SECOND DELAY; (WHICH INDICATED TO US THEY HAD LOST SIGHT OF US); THEY THEN SAID THEY SAW US AT THE SAME TIME WE CROSSED DIRECTLY OVER THEM AT A CONVERGING HDGS. WE DID NOT SEE THE SINGLE ENG CESSNA UNTIL THIS TIME. APCH CTL ASKED US IF WE HAD RECEIVED AN RA AND WE SAID WE DID BUT THEY DID NOT INDICATE WHETHER A NEAR MID-AIR WOULD BE FILED ON THE CESSNA. SUPPLEMENTAL INFO FROM ACN 286382: I MADE VISUAL CONTACT WITH THE CESSNA JUST IN TIME TO SEE HIM PASS DIRECTLY UNDERNEATH US. OUR TCASII INDICATED HIS ALT TO BE 200 FT BENEATH US. HE CLRLY DID NOT HAVE US IN SIGHT OR HAD LOST VISUAL CONTACT WITH US.
