SMT OVERSHOT FINAL APCH COURSE FOR THE R RWY AND HAD NMAC WITH AN MDT ON FINAL APCH TO THE L HAND PARALLEL RWY.

Narrative

WAS BEING VECTORED TO VISUAL APCH TO RWY 36R AT CLT. 210 KTS DOWNWIND VECTOR; DSNDING FROM 8000 TO 3000. NEXT VECTORED TO 270 DEG AND TOLD TO LOOK FOR WDB AND SLOW TO 190 KTS. NEXT TOLD TO SLOW TO 170 KTS. WE CALLED FIELD IN SIGHT LOOKING FOR WDB; IMMEDIATELY FOLLOWED BY WDB IN SIGHT. AT THIS POINT; APCH SAID SLOW TO 150 AND CLRED TO FOLLOW WDB TO 36R. WE WERE STILL ON THE 270 DEG HDG AND SLOWING AS FAST AS WE COULD. WE WERE TOO CLOSE TO THE HVY WDB TO TURN TO 360 DEG. THE ONLY OPTION WAS TO LEVEL AT 3500 FT AND CROSS THE LOC TO GET THE REQUIRED SEPARATION WITH THE WDB. SINCE OUR ATTN WAS ON THE WDB AND WE WERE IN A R TURN BACK TO LOC WE COULD NOT SEE ANOTHER ACFT ON APCH TO 36L. THERE WAS NO MENTION OF THIS OTHER ACFT UNTIL A CONFLICT HAD OCCURRED. I CALLED TWR AFTER LNDG AND WAS TOLD THEY DO NOT MENTION TFC TO THE PARALLEL RWY SINCE THEY SAY ON ATIS 'SIMULTANEOUS APCHS TO 36R AND 36L.' ALL OTHER FIELDS (36) THAT I FLY TO; APCH CTL ALWAYS GIVES A TFC CALL FOR ACFT LNDG ON A PARALLEL RWY. 3 THINGS COULD HAVE AVOIDED THIS INCIDENT. A CALL TO SLOW TO 170 ON THE DOWNWIND VECTOR. AN EARLIER HEADS UP THAT OUR INTERVAL WAS A HVY AND A TA REFERENCING THE PARALLEL RWY TFC. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. RPTR WAS NOT TCASII EQUIPPED. HE DID NOT NOTICE THE THIRD ACFT THAT WAS ON FINAL RWY 36L WHILE HE WAS WBOUND TRYING TO INCREASE SPACING ON THE WDB. HE MADE A LOOSE TURN TRYING TO INCREASE SPACING. HE THINKS THIS WOULD NOT HAVE HAPPENED IF THE CTLR HAD POINTED OUT THE MDT ON FINAL FOR THE L RWY. RPTR SELDOM FLIES TO CTL. MDT WAS INTERCEPTING 36L FINAL.
