Narrative:

At about H10 pm my student and I departed newton runway 17 for multiple lndgs. After our second touch-and-go, we heard ny report entering left downwind for 17 at newton. Both planes completed 1 trip around the pattern with Y in the front. We were departing the pattern to the west. My student reported that we were 4 mi to the west of the airport and inbound for landing on runway 17. At this time another plane, Z, reported 8 mi north. Z reported a 'long final' for runway 17. I saw Y just taking off runway 17. At this time Z reported that he was on a 3 mi final and did not have us in sight. I knew that Y was behind us at this time because I saw them turn left crosswind as we turned left downwind. My student had reported when we turned left base when I noticed that my student had not allowed for enough spacing between us and Z who was now on about a 1 mi final. At this time I took control of the plane and extended 20 degrees of flaps and did some shallow s- turns to provide the necessary spacing. When we were at about 500 ft AGL and on about a 1/2 mi final, Y overtook us and passed above and to our left. I estimate that Y was closer than 200 ft away, and we encountered a short period of turbulence from the propwash and wingtip vortices. I immediately reported that we were on a 1/2 mi final and Y also reported a 1/2 mi final. I decided that we should abandon the landing and perform a go around. I announced our intentions. Z announced that he had cleared runway 17. Y continued with the approach and did a touch-and-go. I announced that we were doing a climbing right 270 degree turn to re-cross midfield and enter the left downwind for runway 17. Today, I discussed this event with the chief instructor as to what should be done about this incident. I realize that the FARS do not mandate that pilots report their position and intentions in the traffic pattern at a non-twred airport, however, the basic responsibility of 'see and avoid' applies at all times, in addition, far 91.111 (G) applies to this situation.

Title: THERE WERE 3 SMA ACFT IN A NIGHT TOUCH-AND-GO PATTERN. 2 HAD AN NMAC.

Narrative: AT ABOUT H10 PM MY STUDENT AND I DEPARTED NEWTON RWY 17 FOR MULTIPLE LNDGS. AFTER OUR SECOND TOUCH-AND-GO, WE HEARD NY RPT ENTERING L DOWNWIND FOR 17 AT NEWTON. BOTH PLANES COMPLETED 1 TRIP AROUND THE PATTERN WITH Y IN THE FRONT. WE WERE DEPARTING THE PATTERN TO THE W. MY STUDENT RPTED THAT WE WERE 4 MI TO THE W OF THE ARPT AND INBOUND FOR LNDG ON RWY 17. AT THIS TIME ANOTHER PLANE, Z, RPTED 8 MI N. Z RPTED A 'LONG FINAL' FOR RWY 17. I SAW Y JUST TAKING OFF RWY 17. AT THIS TIME Z RPTED THAT HE WAS ON A 3 MI FINAL AND DID NOT HAVE US IN SIGHT. I KNEW THAT Y WAS BEHIND US AT THIS TIME BECAUSE I SAW THEM TURN L XWIND AS WE TURNED L DOWNWIND. MY STUDENT HAD RPTED WHEN WE TURNED L BASE WHEN I NOTICED THAT MY STUDENT HAD NOT ALLOWED FOR ENOUGH SPACING BTWN US AND Z WHO WAS NOW ON ABOUT A 1 MI FINAL. AT THIS TIME I TOOK CTL OF THE PLANE AND EXTENDED 20 DEGS OF FLAPS AND DID SOME SHALLOW S- TURNS TO PROVIDE THE NECESSARY SPACING. WHEN WE WERE AT ABOUT 500 FT AGL AND ON ABOUT A 1/2 MI FINAL, Y OVERTOOK US AND PASSED ABOVE AND TO OUR L. I ESTIMATE THAT Y WAS CLOSER THAN 200 FT AWAY, AND WE ENCOUNTERED A SHORT PERIOD OF TURB FROM THE PROPWASH AND WINGTIP VORTICES. I IMMEDIATELY RPTED THAT WE WERE ON A 1/2 MI FINAL AND Y ALSO RPTED A 1/2 MI FINAL. I DECIDED THAT WE SHOULD ABANDON THE LNDG AND PERFORM A GAR. I ANNOUNCED OUR INTENTIONS. Z ANNOUNCED THAT HE HAD CLRED RWY 17. Y CONTINUED WITH THE APCH AND DID A TOUCH-AND-GO. I ANNOUNCED THAT WE WERE DOING A CLBING R 270 DEG TURN TO RE-CROSS MIDFIELD AND ENTER THE L DOWNWIND FOR RWY 17. TODAY, I DISCUSSED THIS EVENT WITH THE CHIEF INSTRUCTOR AS TO WHAT SHOULD BE DONE ABOUT THIS INCIDENT. I REALIZE THAT THE FARS DO NOT MANDATE THAT PLTS RPT THEIR POS AND INTENTIONS IN THE TFC PATTERN AT A NON-TWRED ARPT, HOWEVER, THE BASIC RESPONSIBILITY OF 'SEE AND AVOID' APPLIES AT ALL TIMES, IN ADDITION, FAR 91.111 (G) APPLIES TO THIS SITUATION.
