MLG HAS NMAC WITH VFR SMA TFC.

Narrative

MLG X NBOUND ON VECTORS TO ILS RWY 6 AT BDL DSNDING FROM 10000; AND AN SMA Y VFR WBOUND CLBING TO 6500. SMA Y WAS TOLD THAT 'UPON REACHING 6500 FT' TO 'RPT PRIOR TO CHANGING ALT.' WHEN ACFT WERE APPROX 10 MI APART; TFC WAS EXCHANGED. SMA Y WAS MISRPTED TO MLG X AS BEING AN SMA YA TYPE. SMA Y RPTED MLG X IN SIGHT. MLG X WAS STILL LOOKING FOR THE TFC. AT THIS POINT THE DATA TAGS OVERLAPPED AND WERE BASICALLY UNREADABLE. (NO EXCUSE FOR THIS I WASN'T BUSY ENOUGH TO INSURE THAT THEY DIDN'T.) MLG X THEN SHOUTED 'IS IT AN SMA Y?' I REPLIED THAT IT MIGHT BE. HE SHOULD BE PASSING BENEATH HIM AT THAT TIME (DATA TAGS UNREADABLE). MLG X THEN RPTED THAT THE TFC HAD JUST OVERFLOWN HIM. WHEN DATA TAGS SEPARATED THE SMA Y WAS 1/2 MI BEHIND AND 100 FT ABOVE MLG X. WHEN QUESTIONED THE SMA Y PLT STATED HE WAS TRYING TO AVOID MLG X WAKE TURB. THE PROBLEM HERE WAS THAT THE PLT DID NOT RPT CHANGING HIS ALT AND THAT I ALLOWED THE DATA TAGS TO OVERLAP AND THEREFORE DID NOT SEE THE SMA Y CLBING THROUGH HIS SUPPOSED CRUISING ALT. HOPEFULLY A LESSON LEARNED ON BOTH PARTS. ALSO: WHEN PASSING TFC; ENSURE THAT YOU KNOW THE CORRECT ACFT TYPE IF AVAILABLE. SUPPLEMENTAL INFO FROM ACN 209977: MLG WAS THEN CLRED FROM 7000 THROUGH MY ALT TO 5000 AND A TURN INTO ME. I HAD LEVELED AT 6500 AND WAS KEEPING VISUAL SEPARATION FROM THE TFC. MLG WAS ADVISED OF AN SMA Y ACFT AT MY POS. THE CAPT THEN ASKED IF BDL ATC WAS PICKING UP AN SMA X; HIGH WING NOT AN SMA Y; LOW WING THAT WAS HIGHER THAN HIMSELF. AT THIS TIME I ALREADY STARTED EVASIVE ACTION TO AVOID THE JET AND HIS WAKE TURB BY CLBING AND A L TURN TO 7000. ATC TOLD MLG JET TO LOOK FOR AN SMA Y WHEN I WAS AN SMA X AND TURNED HIM R AND DSNDED HIM THROUGH MY ALT AND AT ME. I WAS BUSY FLYING AND CALMING MY PAX DOWN AND GAINED 500 FT BTWN ALL THAT TO NOTIFY ATC. COM BTWN THE CTLR AND MLG WAS NOT GOOD AND I FAILED TO NOTIFY ATC OF MY EVASIVE ACTION TO AVOID THE JET. ATC SHOULD HAVE NOT TURNED THE JET UNTIL I WAS IN SIGHT BY THE JET OR GIVE ME A VECTOR AROUND HIM OR VICE VERSA. I ACTED ON SEE AND AVOID.
