AN AIR TAXI JET CAPT RPTS THAT A LAS APCH CTLR'S VECTOR CLRNC PLACED THEIR ACFT ON A COLLISION COURSE WITH AN MD80. THE MD80 FLC TOOK EVASIVE ACTION; DSNDING AND PASSING APPROX 500 FT BELOW THEM.

Narrative

WE WERE APCHING LAS FROM THE E WITH A HDG TO INTERCEPT THE ILS FOR LNDG ON RWY 1R. WE WERE AT 8000 FT AND THE CTLR BROUGHT US ALMOST TO THE ARPT AT WHICH POINT HE TURNED US TO A HDG OF 190 DEGS AND TURNED US OVER TO THE FINAL CTLR. THE FINAL CTLR GAVE US AN IMMEDIATE DSCNT TO 6000 FT AS WE HAD TFC AT 12 O'CLOCK AND 1 MI AT 8000 FT. I LOOKED OUT TO SEE AN MD80 PASSING APPROX 500 FT BELOW US. FORTUNATELY; THEY EITHER SAW US OR HAD US ON TCASII AND INITIATED A DSCNT ON THEIR OWN. THERE IS NO DOUBT IN MY MIND THAT IF I HAD STARTED THAT TYPE OF DSCNT AT THAT TIME; WE WOULD HAVE HIT THE MD80. WE TOLD THE CTLR THAT WE HAD TFC BELOW US AND SHE TOLD US TO MAINTAIN 8000 FT. AFTER THAT; SHE WAS REPLACED AND A NEW CTLR CAME ON AND NOTHING ELSE WAS SAID ABOUT THE INCIDENT. I DO NOT FEEL THAT THE FINAL CTLR WAS AT FAULT BUT THAT THE PREVIOUS CTLR WAS THE ONE WHO TURNED US INTO THE ONCOMING TFC. I HAD SEEN THE TFC EARLIER WHEN THE SUN REFLECTED OFF HIS WINGS; BUT LOST HIM IN THE BACKGND. I NEVER GAVE IT A THOUGHT THAT THEY WOULD BRING TFC FROM THE W OVER THE ARPT FOR R TFC FOR RWY 1R. I DO; HOWEVER; FEEL THAT THIS WAS A CTLR ERROR. ANOTHER GOTCHA FROM THE WARM AND FUZZY FEELING OF BEING IN RADAR CTL.
