Narrative:

We were descending from 7500 ft MSL on a heading of 110 degree through 6500 ft. A rising column of warm air briefly slowed our descent rate. The copilot and I were briefly talking about the airplane to each other. I turned my head back to forward and initiated a left turn during the descent. Immediately, I saw the right wing tip strobe light of an small aircraft. The small aircraft passed from my left to right on an approximately heading of 200 degree. There was no indication that he saw us. Our strobe lights were on also. I was monitoring green bay approach for traffic at that time. I next contacted green bay approach explained what happened and received a transponder code for flight following while in their airspace.

Title: 2 SMAS HAD A NMAC IN VMC.

Narrative: WE WERE DSNDING FROM 7500 FT MSL ON A HDG OF 110 DEG THROUGH 6500 FT. A RISING COLUMN OF WARM AIR BRIEFLY SLOWED OUR DSCNT RATE. THE COPLT AND I WERE BRIEFLY TALKING ABOUT THE AIRPLANE TO EACH OTHER. I TURNED MY HEAD BACK TO FORWARD AND INITIATED A L TURN DURING THE DSCNT. IMMEDIATELY, I SAW THE R WING TIP STROBE LIGHT OF AN SMA. THE SMA PASSED FROM MY L TO R ON AN APPROX HDG OF 200 DEG. THERE WAS NO INDICATION THAT HE SAW US. OUR STROBE LIGHTS WERE ON ALSO. I WAS MONITORING GREEN BAY APCH FOR TFC AT THAT TIME. I NEXT CONTACTED GREEN BAY APCH EXPLAINED WHAT HAPPENED AND RECEIVED A TRANSPONDER CODE FOR FLT FOLLOWING WHILE IN THEIR AIRSPACE.
