THE RPTR WAS VECTORED TO A FINAL AT 5000 FT FOR AN ILS APCH. THE CTLR DEEMED THE POS TOO HIGH AND TOO CLOSE TO INTERCEPT THE ILS FROM ABOVE. THE CTLR WANTED TO RETURN THE PLT OUTBOUND FOR A VECTOR TO THE ILS AT A PROPER ALT AND DISTANCE. THE PLT STARTED TO DSND SAYING HE COULD MAKE IT. THE CTLR SAID HE WAS NOT CLRED FOR THE APCH AND RETURN TO 5000 FT; THE PLT HAD DEVIATED FROM HIS ASSIGNED ALT AND COMPROMISED SEPARATION FROM ANOTHER ACFT. THE PLT COMPLIED.

Narrative

IN IMC I WAS ON A RADAR VECTOR FOR THE ILS RWY 12 SMX. THE DOWNWIND TOOK ME SW OF THE FINAL APCH COURSE. THE CTLR TURNED ME TO 360 DEGS FOR BASE AND THEN TO 090 DEGS TO INTERCEPT AND REQUESTED I 'RPT ESTABLISHED.' AT THIS TIME HE DID NOT OFFER LOWER ALT NOR DID HE ALERT ME TO OTHER TFC. AS I HAD BEEN 'SLAM DUNKED' ON THIS APCH SEVERAL TIMES BEFORE WITH A SW DOWNWIND I ASSUMED IT HAD TO DO WITH R2516 TO THE SW. THE LOC STARTED TO CTR WHEN I WAS ONLY 2 MI FROM THE OM AND 3000 FT ABOVE GS INTERCEPT. WHEN I RPTED ESTABLISHED; IT WAS IN MY MIND I WAS CLRED FOR THE APCH AND STARTED TO DSND. AS I PASSED 4600 FT (APPROX) THE CTLR TOLD ME TO TURN R AS I WAS 'TOO CLOSE IN TO MAKE THE APCH FROM THAT POS.' THE CTLR NEVER SAID ANYTHING ABOUT CONFLICTING TFC. I TOLD THE CTLR I COULD MAKE THE APCH FROM THIS POS (7.2 APPROX) BUT BY THE TIME HE RESPONDED I REALIZED IT WAS TOO LATE AND I WAS IN TOO CLOSE. THE CTLR THEN TOLD ME MY ASSIGNED ALT 'IS AND WAS 5000 FT' AND TO TURN R TO REINTERCEPT. I IMMEDIATELY CLBED TO 5000 FT AND TURNED R. AT THIS TIME I TOLD THE CTLR I WOULD BE IN THE SAME POS AS BEFORE. IT WAS AT THIS TIME HE TOLD ME OF A TFC CONFLICT; CLRED ME FOR THE APCH AND TOLD ME OF A POSSIBLE PLTDEV. ALTHOUGH I CLRLY SHOULD NOT HAVE DSNDED FROM 5000 FT WITHOUT VERIFYING I WAS CLRED FOR THE APCH (I THOUGHT I WAS) I FEEL THE CTLR SHOULD HAVE EXTENDED THE DOWNWIND TO PROVIDE MORE SEPARATION RATHER THAN HOLD ME HIGH; PASS THE TFC UNDERNEATH AND THEN TRY TO 'SLAM DUNK' ME. I ALSO FEEL THE CTLR SHOULD HAVE TOLD ME OF THE TFC CONFLICT AND WHY HE WAS HOLDING ME AT 5000 FT. IT SHOULD HAVE BEEN CLR TO THE CTLR LONG BEFORE THIS INCIDENT OCCURRED THAT THE APCH WOULD NOT WORK FROM THAT ALT WITH THE TFC HE HAD IN FRONT OF ME THAT HE DID NOT TELL ME ABOUT. BOTH THE PLT AND THE CTLR CAUSE THIS INCIDENT TO DEVELOP BECAUSE OF MISCOM; A LACK OF INFO PROVIDED TO THE PLT AND ANTICIPATION OF CTLR ACTION BY THE PLT.
