Narrative:
Descending into ogg, put on vectors to ILS runway 2, descend to 3500', given intercept heading, then cleared for the approach. Nearing the localizer, several altitude clearance changes were made in rapid succession, and traffic was called at 11 O'clock, which we sighted and reported in sight. We also reported airport in sight. We were then cleared for a visibility approach. We turned left of course to avoid clouds which were on the localizer course. We then spotted an small aircraft at 12 O'clock, 1/4 mi, 100' above us. We turned left and descended to avoid a collision. The small plane was under radar control at the time and had been advised to remain east of the approach course, and had been given a heading of 090 degrees. Instead, he was dead center on the localizer and G/south. Due to his proximity to the clouds on final, had we continued to intercept the ILS, we probably would have collided.

Title: ACR MAKING A VISUAL APCH TO ARPT CAME IN CLOSE PROX TO AN SMA ON FINAL APCH.
Narrative: DSNDING INTO OGG, PUT ON VECTORS TO ILS RWY 2, DSND TO 3500', GIVEN INTERCEPT HDG, THEN CLRED FOR THE APCH. NEARING THE LOC, SEVERAL ALT CLRNC CHANGES WERE MADE IN RAPID SUCCESSION, AND TFC WAS CALLED AT 11 O'CLOCK, WHICH WE SIGHTED AND RPTED IN SIGHT. WE ALSO RPTED ARPT IN SIGHT. WE WERE THEN CLRED FOR A VIS APCH. WE TURNED LEFT OF COURSE TO AVOID CLOUDS WHICH WERE ON THE LOC COURSE. WE THEN SPOTTED AN SMA AT 12 O'CLOCK, 1/4 MI, 100' ABOVE US. WE TURNED LEFT AND DSNDED TO AVOID A COLLISION. THE SMALL PLANE WAS UNDER RADAR CTL AT THE TIME AND HAD BEEN ADVISED TO REMAIN E OF THE APCH COURSE, AND HAD BEEN GIVEN A HDG OF 090 DEGS. INSTEAD, HE WAS DEAD CENTER ON THE LOC AND G/S. DUE TO HIS PROX TO THE CLOUDS ON FINAL, HAD WE CONTINUED TO INTERCEPT THE ILS, WE PROBABLY WOULD HAVE COLLIDED.
