Narrative:

At the aransas county airport I was in the touch and go pattern. I called turning crosswind on runway 27. After turning downwind, the radio traffic was heavy with several aircraft checking in with position reports. Several experimental aircraft were checking in with bad radios. There was, I would estimate, about 4- 5 aircraft coming in to land at the same time while I was in the touch and go pattern. One aircraft joined the downwind leg behind me and the experimental aircraft were some distance away and another aircraft kept calling long final into rockport. I never saw the aircraft on long final and as far as I know, the aircraft did not join the pattern as per the aim at uncontrolled airports. I checked the traffic turning base from downwind and didn't see any, so I called the turn. Seems like the C172 on long final made another call, but with all of the radio traffic I didn't really pick up the call. I then called 'aircraft on long final say your position' and didn't get a response. So I turned from base to final, then the student in the front seat saw a shadow on the ground and then I saw the aircraft on short final. I estimate his altitude at about 100-150 ft and my altitude at about 400-500 ft. I then flew through the extended centerline and flew the aircraft up the left side of the runway 27 to keep the landing traffic in sight. Runway 27 is right hand traffic. Contributing factors: 1) radio traffic, everyone reporting position, and bad radios causing other aircraft to tune out the radios. 2) mix of high wing and low wing aircraft, makes it hard to see each other. 3) long final. Callback conversation with reporter revealed the following information: reporter states that the C172 pilot told him 'you need to call the FSDO' when reporter made the go around. When he landed he made an attempt to talk to the other pilot but he was taxiing back to depart. ATC at corpus christi contacted reporter and said the airport manager had called in response to a complaint. When reporter described the incident ATC indicated it would go no further. There are occasionally problems in the area with aircraft from an aeronautical club practicing at rkp and the airport manager wanted to check out this incident. The D-45 is a certified version of the T34B mentor which is military and not certified.

Title: D-45 (MENTOR) WITH INSTRUCTOR AND STUDENT ABOARD HAS NMAC WITH A C172 MAKING A STRAIGHT IN APCH AT A NON TWR ARPT. THE MENTOR MAKES A GAR.

Narrative: AT THE ARANSAS COUNTY ARPT I WAS IN THE TOUCH AND GO PATTERN. I CALLED TURNING XWIND ON RWY 27. AFTER TURNING DOWNWIND, THE RADIO TFC WAS HVY WITH SEVERAL ACFT CHKING IN WITH POS RPTS. SEVERAL EXPERIMENTAL ACFT WERE CHKING IN WITH BAD RADIOS. THERE WAS, I WOULD ESTIMATE, ABOUT 4- 5 ACFT COMING IN TO LAND AT THE SAME TIME WHILE I WAS IN THE TOUCH AND GO PATTERN. ONE ACFT JOINED THE DOWNWIND LEG BEHIND ME AND THE EXPERIMENTAL ACFT WERE SOME DISTANCE AWAY AND ANOTHER ACFT KEPT CALLING LONG FINAL INTO ROCKPORT. I NEVER SAW THE ACFT ON LONG FINAL AND AS FAR AS I KNOW, THE ACFT DID NOT JOIN THE PATTERN AS PER THE AIM AT UNCTLED ARPTS. I CHKED THE TFC TURNING BASE FROM DOWNWIND AND DIDN'T SEE ANY, SO I CALLED THE TURN. SEEMS LIKE THE C172 ON LONG FINAL MADE ANOTHER CALL, BUT WITH ALL OF THE RADIO TFC I DIDN'T REALLY PICK UP THE CALL. I THEN CALLED 'ACFT ON LONG FINAL SAY YOUR POS' AND DIDN'T GET A RESPONSE. SO I TURNED FROM BASE TO FINAL, THEN THE STUDENT IN THE FRONT SEAT SAW A SHADOW ON THE GND AND THEN I SAW THE ACFT ON SHORT FINAL. I ESTIMATE HIS ALT AT ABOUT 100-150 FT AND MY ALT AT ABOUT 400-500 FT. I THEN FLEW THROUGH THE EXTENDED CTRLINE AND FLEW THE ACFT UP THE L SIDE OF THE RWY 27 TO KEEP THE LNDG TFC IN SIGHT. RWY 27 IS R HAND TFC. CONTRIBUTING FACTORS: 1) RADIO TFC, EVERYONE RPTING POS, AND BAD RADIOS CAUSING OTHER ACFT TO TUNE OUT THE RADIOS. 2) MIX OF HIGH WING AND LOW WING ACFT, MAKES IT HARD TO SEE EACH OTHER. 3) LONG FINAL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT THE C172 PLT TOLD HIM 'YOU NEED TO CALL THE FSDO' WHEN RPTR MADE THE GAR. WHEN HE LANDED HE MADE AN ATTEMPT TO TALK TO THE OTHER PLT BUT HE WAS TAXIING BACK TO DEPART. ATC AT CORPUS CHRISTI CONTACTED RPTR AND SAID THE ARPT MGR HAD CALLED IN RESPONSE TO A COMPLAINT. WHEN RPTR DESCRIBED THE INCIDENT ATC INDICATED IT WOULD GO NO FURTHER. THERE ARE OCCASIONALLY PROBS IN THE AREA WITH ACFT FROM AN AERO CLUB PRACTICING AT RKP AND THE ARPT MGR WANTED TO CHK OUT THIS INCIDENT. THE D-45 IS A CERTIFIED VERSION OF THE T34B MENTOR WHICH IS MIL AND NOT CERTIFIED.
