Narrative:

My student and myself were perfecting lndgs and takeoffs. We takeoff from N81 at approximately xapm, stayed in pattern. We announced our intensions throughout pattern. Spoke to a pilot doing a VOR app to airport. Advising him that we were in the pattern and position and intentions, I advised my stuednt to be aware of landing position, (runway 03 active with wind directly down the runway) try to land near or on the #3 looking at the centerline he did as I recommended. Our wheels were just touching down, when I saw another aircraft (twin) just about to touch down on runway 21. I instructed my student to move onto the grass between the runway and taxiway quickly, which he did. The twin flew by us (he had a good tail win). I got on (122.7) the radio asking what his intentions were. A helicopter pilot over head mentioned on 122.7 that the twin was broadcasting on 122.8 not our unicom frequency. I switched over to 122.8 and asked the same question! What I received was back talk and belligerence. He felt that there was no need for upsetment 'we weren't that close to cause problem'. He had no landing lights on, not on the correct frequency for our airport. If we didn't move to the right and get off the runway two planes would have collided. He went to fuel pump and left the airport. Didn't announce his departure, did not fly a standard departure form an uncontrolled fld, but did use his taxi landing lights. We continued to fly the pattern with more vigilance, making sure no traffic was on runway 21. Later that day two other pilots mentioned that they heard him announce entering the pattern on a base leg and turning final, not realizing that he was not on the correct frequency. Callback conversation with reporter revealed the following information: reporter states that her student did not react when asked to leave the runway and taxi onto the grass. Instrument took over and got the aircraft as far off as it was safe. Other aircraft passed at high speed since he had a tail wind and rolled to the end of the runway before stopping. In 30 years of flying this was the most scary incident instructor has experienced and the other pilot did not think it was too bad. Apparently the twin comanche pilot made a straight in approach or a slight base leg and that contributed to their lack of sighting the aircraft. The twin comanche is registered to a corporation. Airport has super unicom which gives automated information regarding active runway and current conditions, but it is on the CTAF frequency. So second pilot would not have received it on his frequency.

Title: FLT INSTRUCTOR WITH STUDENT ON TOUCH DOWN AT A NON TWR ARPT, SIGHTS A PA30 ON TOUCH DOWN OPPOSITE DIRECTION. THE BE24R TAXIES TO THE GRASS BETWEEN RWY AND TXWY TO AVOID COLLISION. SECOND ACFT WAS ON WRONG FREQ.

Narrative: MY STUDENT AND MYSELF WERE PERFECTING LNDGS AND TKOFS. WE TKOF FROM N81 AT APPROX XAPM, STAYED IN PATTERN. WE ANNOUNCED OUR INTENSIONS THROUGHOUT PATTERN. SPOKE TO A PLT DOING A VOR APP TO ARPT. ADVISING HIM THAT WE WERE IN THE PATTERN AND POSITION AND INTENTIONS, I ADVISED MY STUEDNT TO BE AWARE OF LNDG POS, (RWY 03 ACTIVE WITH WIND DIRECTLY DOWN THE RWY) TRY TO LAND NEAR OR ON THE #3 LOOKING AT THE CTRLINE HE DID AS I RECOMMENDED. OUR WHEELS WERE JUST TOUCHING DOWN, WHEN I SAW ANOTHER ACFT (TWIN) JUST ABOUT TO TOUCH DOWN ON RWY 21. I INSTRUCTED MY STUDENT TO MOVE ONTO THE GRASS BETWEEN THE RWY AND TXWY QUICKLY, WHICH HE DID. THE TWIN FLEW BY US (HE HAD A GOOD TAIL WIN). I GOT ON (122.7) THE RADIO ASKING WHAT HIS INTENTIONS WERE. A HELICOPTER PLT OVER HEAD MENTIONED ON 122.7 THAT THE TWIN WAS BROADCASTING ON 122.8 NOT OUR UNICOM FREQUENCY. I SWITCHED OVER TO 122.8 AND ASKED THE SAME QUESTION! WHAT I RECEIVED WAS BACK TALK AND BELLIGERENCE. HE FELT THAT THERE WAS NO NEED FOR UPSETMENT 'WE WEREN'T THAT CLOSE TO CAUSE PROB'. HE HAD NO LNDG LIGHTS ON, NOT ON THE CORRECT FREQUENCY FOR OUR ARPT. IF WE DIDN'T MOVE TO THE R AND GET OFF THE RWY TWO PLANES WOULD HAVE COLLIDED. HE WENT TO FUEL PUMP AND LEFT THE ARPT. DIDN'T ANNOUNCE HIS DEP, DID NOT FLY A STD DEP FORM AN UNCONTROLLED FLD, BUT DID USE HIS TAXI LNDG LIGHTS. WE CONTINUED TO FLY THE PATTERN WITH MORE VIGILANCE, MAKING SURE NO TFC WAS ON RWY 21. LATER THAT DAY TWO OTHER PLTS MENTIONED THAT THEY HEARD HIM ANNOUNCE ENTERING THE PATTERN ON A BASE LEG AND TURNING FINAL, NOT REALIZING THAT HE WAS NOT ON THE CORRECT FREQ. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT HER STUDENT DID NOT REACT WHEN ASKED TO LEAVE THE RWY AND TAXI ONTO THE GRASS. INSTR TOOK OVER AND GOT THE ACFT AS FAR OFF AS IT WAS SAFE. OTHER ACFT PASSED AT HIGH SPEED SINCE HE HAD A TAIL WIND AND ROLLED TO THE END OF THE RWY BEFORE STOPPING. IN 30 YEARS OF FLYING THIS WAS THE MOST SCARY INCIDENT INSTRUCTOR HAS EXPERIENCED AND THE OTHER PLT DID NOT THINK IT WAS TOO BAD. APPARENTLY THE TWIN COMANCHE PLT MADE A STRAIGHT IN APCH OR A SLIGHT BASE LEG AND THAT CONTRIBUTED TO THEIR LACK OF SIGHTING THE ACFT. THE TWIN COMANCHE IS REGISTERED TO A CORPORATION. ARPT HAS SUPER UNICOM WHICH GIVES AUTOMATED INFO REGARDING ACTIVE RWY AND CURRENT CONDITIONS, BUT IT IS ON THE CTAF FREQ. SO SECOND PLT WOULD NOT HAVE RECEIVED IT ON HIS FREQ.
