Airspace Structure; Procedure
On right downwind for Runway 13 a Piper Seneca that had departed after us flew about 100 FT over us. We noticed the traffic at the last second and pitched down to avoid a collision. The Piper had turned early from the upwind leg during their departure to the south and that put them on a collision course with our aircraft flying downwind. We did not receive any traffic alerts from Tower. When I asked Tower why we didn't receive any alert he said that the radar track showed them passing behind us.
A DA20 instructor pilot and his student in the traffic pattern experienced an NMAC with a Piper Seneca that had taken off after them but passed overhead 100 FT while on downwind.
