Narrative:

In an small aircraft X I was doing a second and final touch-and-go followed by straight out departure at danbury airport runway 17. As #4 I lost my traffic, a white small aircraft Y on downwind (6 total in pattern) and then picked up an small aircraft Y (white) on base. I followed this traffic which turned out to be the wrong traffic and found myself too close to it and in turning final not far away from the next aircraft on final. In doing my touch- and-go I barely touched down and did an immediate climb out, maximum rate, to open up space. In doing so, I lost sight of my traffic ahead due to high angle of climb. I out-climbed my traffic, small aircraft Z, picked him up underneath me by 150-200 ft, turning crosswind as I proceeded out of air traffic area.

Original NASA ASRS Text

Title: NMAC IN TFC PATTERN.

Narrative: IN AN SMA X I WAS DOING A SECOND AND FINAL TOUCH-AND-GO FOLLOWED BY STRAIGHT OUT DEP AT DANBURY ARPT RWY 17. AS #4 I LOST MY TFC, A WHITE SMA Y ON DOWNWIND (6 TOTAL IN PATTERN) AND THEN PICKED UP AN SMA Y (WHITE) ON BASE. I FOLLOWED THIS TFC WHICH TURNED OUT TO BE THE WRONG TFC AND FOUND MYSELF TOO CLOSE TO IT AND IN TURNING FINAL NOT FAR AWAY FROM THE NEXT ACFT ON FINAL. IN DOING MY TOUCH- AND-GO I BARELY TOUCHED DOWN AND DID AN IMMEDIATE CLBOUT, MAX RATE, TO OPEN UP SPACE. IN DOING SO, I LOST SIGHT OF MY TFC AHEAD DUE TO HIGH ANGLE OF CLB. I OUT-CLBED MY TFC, SMA Z, PICKED HIM UP UNDERNEATH ME BY 150-200 FT, TURNING XWIND AS I PROCEEDED OUT OF ATA.
