Narrative:

Me and my student was on a 1 mi final for runway 2 at the john C tune airport at 500 ft AGL and v-tail bonanza cut me in from a base at about 50 ft above from us and land front of us. Never talked on a radio; never responded to our call. I could not get a tail number and that bonanza is not base at john C tune airport. They just left after that incident. It was so close that scared my student and we had to turn right to avoid that aircraft. Since we were flying a C172; so I did not see that bonanza because they were higher altitude than we were and; of course; they were not talking on a radio so it was a total surprise. As a CFI; I think radio calls should be mandatory at any class east and G airport. I am very frustrated about the many pilots does not know about the regulations and a procedures at the non-control airport. I as a CFI have a responsibility to make a GA safe and I'm doing my best to educate a student but some already a pilot does not comply with a procedure is very discouraging.

Narrative: ME AND MY STUDENT WAS ON A 1 MI FINAL FOR RWY 2 AT THE JOHN C TUNE ARPT AT 500 FT AGL AND V-TAIL BONANZA CUT ME IN FROM A BASE AT ABOUT 50 FT ABOVE FROM US AND LAND FRONT OF US. NEVER TALKED ON A RADIO; NEVER RESPONDED TO OUR CALL. I COULD NOT GET A TAIL NUMBER AND THAT BONANZA IS NOT BASE AT JOHN C TUNE ARPT. THEY JUST LEFT AFTER THAT INCIDENT. IT WAS SO CLOSE THAT SCARED MY STUDENT AND WE HAD TO TURN R TO AVOID THAT ACFT. SINCE WE WERE FLYING A C172; SO I DID NOT SEE THAT BONANZA BECAUSE THEY WERE HIGHER ALT THAN WE WERE AND; OF COURSE; THEY WERE NOT TALKING ON A RADIO SO IT WAS A TOTAL SURPRISE. AS A CFI; I THINK RADIO CALLS SHOULD BE MANDATORY AT ANY CLASS E AND G ARPT. I AM VERY FRUSTRATED ABOUT THE MANY PLTS DOES NOT KNOW ABOUT THE REGS AND A PROCS AT THE NON-CTL ARPT. I AS A CFI HAVE A RESPONSIBILITY TO MAKE A GA SAFE AND I'M DOING MY BEST TO EDUCATE A STUDENT BUT SOME ALREADY A PLT DOES NOT COMPLY WITH A PROC IS VERY DISCOURAGING.
