Narrative:

I had been in the traffic pattern for almost 1 hour with a student, practicing touch-and-go lndgs. We had been making radio calls on each leg of the pattern, per standard procedure. We were also hearing calls from other aircraft, including the other aircraft involved, but very rarely did he transmit anything. As we turned onto final for our last landing of the day, the P51 came swooping over the top of us, no more than 100 ft away. We could hear his engine noise over our own noise and the headsets we were wearing. A few seconds after he flew over, we encountered his wake turbulence, which resulted in violent, sudden banks of at least 45 degrees in each direction, along with nose down pitch changes. At no time did the other airplane call downwind, base, or final. He continued his landing and so did we, landing in the first 500 ft or so of the runway, while he was farther down the end (the runway is 4000 ft long). After his landing, instead of using the parallel taxiway, he proceeded to back-taxi while we were still on the runway, with no available turnoff between the two of us. Despite our efforts to move as far to the right of the runway as possible, his left wingtip struck our left wing, resulting in a small dent and scratched paint. Some witnesses on the ground reported that they had not heard our calls, so we examined the radio and found that there was a condition which may have resulted in the xmissions not getting through all the time. We had no way of knowing this in the air, because we were receiving and the radio sounded normal when transmitting.

Title: C150 PLT HAD AN NMAC ON FINAL AND A GND CONFLICT WITH SAME ACFT WHILE TAXIING.

Narrative: I HAD BEEN IN THE TFC PATTERN FOR ALMOST 1 HR WITH A STUDENT, PRACTICING TOUCH-AND-GO LNDGS. WE HAD BEEN MAKING RADIO CALLS ON EACH LEG OF THE PATTERN, PER STANDARD PROC. WE WERE ALSO HEARING CALLS FROM OTHER ACFT, INCLUDING THE OTHER ACFT INVOLVED, BUT VERY RARELY DID HE XMIT ANYTHING. AS WE TURNED ONTO FINAL FOR OUR LAST LNDG OF THE DAY, THE P51 CAME SWOOPING OVER THE TOP OF US, NO MORE THAN 100 FT AWAY. WE COULD HEAR HIS ENG NOISE OVER OUR OWN NOISE AND THE HEADSETS WE WERE WEARING. A FEW SECONDS AFTER HE FLEW OVER, WE ENCOUNTERED HIS WAKE TURB, WHICH RESULTED IN VIOLENT, SUDDEN BANKS OF AT LEAST 45 DEGS IN EACH DIRECTION, ALONG WITH NOSE DOWN PITCH CHANGES. AT NO TIME DID THE OTHER AIRPLANE CALL DOWNWIND, BASE, OR FINAL. HE CONTINUED HIS LNDG AND SO DID WE, LNDG IN THE FIRST 500 FT OR SO OF THE RWY, WHILE HE WAS FARTHER DOWN THE END (THE RWY IS 4000 FT LONG). AFTER HIS LNDG, INSTEAD OF USING THE PARALLEL TXWY, HE PROCEEDED TO BACK-TAXI WHILE WE WERE STILL ON THE RWY, WITH NO AVAILABLE TURNOFF BTWN THE TWO OF US. DESPITE OUR EFFORTS TO MOVE AS FAR TO THE R OF THE RWY AS POSSIBLE, HIS L WINGTIP STRUCK OUR L WING, RESULTING IN A SMALL DENT AND SCRATCHED PAINT. SOME WITNESSES ON THE GND RPTED THAT THEY HAD NOT HEARD OUR CALLS, SO WE EXAMINED THE RADIO AND FOUND THAT THERE WAS A CONDITION WHICH MAY HAVE RESULTED IN THE XMISSIONS NOT GETTING THROUGH ALL THE TIME. WE HAD NO WAY OF KNOWING THIS IN THE AIR, BECAUSE WE WERE RECEIVING AND THE RADIO SOUNDED NORMAL WHEN XMITTING.
