Narrative:

While level at 4500', heading 246 degrees on victor 106 directly into the sun, bradley approach control instructed me to 'turn right heading 330 degrees for vectors around traffic.' while turning right from a heading of 246 degrees to heading 330 degrees, well into the right hand turn, the converging traffic appeared, taking up the majority of the windshield of the small aircraft I was flying, approximately 20-30 yds away. I took evasive action by executing a quick climbing right turn. It appeared the small transport took no evasive action in this incident. I believed the situation occurred because of the limited visibility due to the sun and because of the vector bradley approach issued me. The altimeter setting I was given was 30-59 (by bradley), the small transport was said to be VFR. I was showing a landing light at the time and I was transponder equipped with mode C. Callback conversation with reporter revealed the following: the reporter filed a near miss report with the FAA and has been advised they are contacting the other pilot. Reporter has also sent a letter requesting the results of their investigation. Reporter said he made a standard rate turn to the heading assigned by bdl as soon as it was given but did not try to talk to bdl about why they gave the vector.

Title: CLOSE PROX GA-SMA GA-SMT ON V106.

Narrative: WHILE LEVEL AT 4500', HDG 246 DEGS ON VICTOR 106 DIRECTLY INTO THE SUN, BRADLEY APCH CTL INSTRUCTED ME TO 'TURN RIGHT HDG 330 DEGS FOR VECTORS AROUND TFC.' WHILE TURNING RIGHT FROM A HDG OF 246 DEGS TO HDG 330 DEGS, WELL INTO THE RIGHT HAND TURN, THE CONVERGING TFC APPEARED, TAKING UP THE MAJORITY OF THE WINDSHIELD OF THE SMA I WAS FLYING, APPROX 20-30 YDS AWAY. I TOOK EVASIVE ACTION BY EXECUTING A QUICK CLBING RIGHT TURN. IT APPEARED THE SMT TOOK NO EVASIVE ACTION IN THIS INCIDENT. I BELIEVED THE SITUATION OCCURRED BECAUSE OF THE LIMITED VIS DUE TO THE SUN AND BECAUSE OF THE VECTOR BRADLEY APCH ISSUED ME. THE ALTIMETER SETTING I WAS GIVEN WAS 30-59 (BY BRADLEY), THE SMT WAS SAID TO BE VFR. I WAS SHOWING A LNDG LIGHT AT THE TIME AND I WAS TRANSPONDER EQUIPPED WITH MODE C. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: THE RPTR FILED A NEAR MISS RPT WITH THE FAA AND HAS BEEN ADVISED THEY ARE CONTACTING THE OTHER PLT. RPTR HAS ALSO SENT A LETTER REQUESTING THE RESULTS OF THEIR INVESTIGATION. RPTR SAID HE MADE A STANDARD RATE TURN TO THE HDG ASSIGNED BY BDL AS SOON AS IT WAS GIVEN BUT DID NOT TRY TO TALK TO BDL ABOUT WHY THEY GAVE THE VECTOR.
