Narrative:

While on final to runway 17, an small aircraft X transmitted his position over unicom to be on downwind to runway 17. When I was unable to locate an aircraft in this area, I did make visual contact with an aircraft located just east of runway 17 at midfield and approximately 500-600' AGL with a west heading. I lost sight of this aircraft for a brief time because of ground clutter. I was unable to get a response on unicom. This aircraft never came back into sight until we were at the same altitude and on a collision course. The small aircraft X never saw us. We were lucky someone was flying outside as well as inside. The small aircraft X never saw us, made a touch and go and departed.

Narrative: WHILE ON FINAL TO RWY 17, AN SMA X TRANSMITTED HIS POS OVER UNICOM TO BE ON DOWNWIND TO RWY 17. WHEN I WAS UNABLE TO LOCATE AN ACFT IN THIS AREA, I DID MAKE VISUAL CONTACT WITH AN ACFT LOCATED JUST E OF RWY 17 AT MIDFIELD AND APPROX 500-600' AGL WITH A W HDG. I LOST SIGHT OF THIS ACFT FOR A BRIEF TIME BECAUSE OF GND CLUTTER. I WAS UNABLE TO GET A RESPONSE ON UNICOM. THIS ACFT NEVER CAME BACK INTO SIGHT UNTIL WE WERE AT THE SAME ALT AND ON A COLLISION COURSE. THE SMA X NEVER SAW US. WE WERE LUCKY SOMEONE WAS FLYING OUTSIDE AS WELL AS INSIDE.
