Narrative:
Aircraft #1 on left downwind leg was sequenced to follow aircraft #2 ahead in the pattern. Aircraft #1 apparently lost his traffic and turned his base and had to 'duck and evade' (likewise for aircraft #2) to avoid collision. WX conditions were such that visibility was poor (with 'greyed-out' backgnd) and visual contact to maintain situational integrity was difficult.
Original NASA ASRS Text
Title: NMAC. PLT OF A PIPER PA28 FAILED TO KEEP THE PIPER PA34 IN SIGHT AS INSTRUCTED BY TWR AND TURNED ONTO FINAL ADJACENT TO THE PA34, CAUSING BOTH PLTS TO TAKE EVASIVE ACTION TO AVOID A COLLISION WITH THE OTHER.
Narrative: ACFT #1 ON L DOWNWIND LEG WAS SEQUENCED TO FOLLOW ACFT #2 AHEAD IN THE PATTERN. ACFT #1 APPARENTLY LOST HIS TFC AND TURNED HIS BASE AND HAD TO 'DUCK AND EVADE' (LIKEWISE FOR ACFT #2) TO AVOID COLLISION. WX CONDITIONS WERE SUCH THAT VISIBILITY WAS POOR (WITH 'GREYED-OUT' BACKGND) AND VISUAL CONTACT TO MAINTAIN SITUATIONAL INTEGRITY WAS DIFFICULT.
