Human Factors
During a VFR training flight; while using published Right Traffic pattern with 45 degree entry. Student & I made the standard self-announce calls at all prescribed locations (45; downwind; base & final. We heard and saw NO other aircraft in the pattern until we were approximately 700 Ft in altitude and 1/4 mile from touchdown on final approach to Runway.A Mooney aircraft suddenly appeared from behind; and on our left; overtaking us and turning in front of us; lining up for landing. As instructor; I took control of aircraft; made several calls to this aircraft and stated the traffic pattern for runway is RIGHT TRAFFIC. I received no response and I initiated a 'go-around' climbing and making an abrupt right turn evasive action to avoid potential collision.At the same time I heard another person on a ground portable radio advise; 'You guys nearly had a mid-air; I'll get his numbers.' My student and I departed the traffic pattern to the east and made a second VFR approach to an uneventful full stop landing. At the fuel pumps; when we landed; I saw the same Mooney aircraft (with only one occupant; the pilot) shutting down to obtain fuel. The Aero Club Chief Flight Instructor; (who had also witnessed this incident) was engaged in conversation with the pilot concerning his near fatal mistake.He later told me that the Mooney had attempted to make a landing on runway 15 (wrong runway for current winds 310 degrees / 14G20 Knots). When the Mooney could not complete the landing he added some power; made a RIGHT 90 degree turn toward the west placing himself directly over the housing area at a low altitude and then made another turn; this time to the left approximately 270 degrees which placed him in DIRECT collision course with me on short final to runway 33. During further discussion (which I also heard) He learned that the pilot was NOT on the proper CTAF frequency. He apparently thought the frequency was 122.9. The proper CTAF frequency is 122.725. During more conversation; he & I learned that the pilot had NOT done any pre-flight planning and therefore was not aware of the published right traffic pattern Runway.In my opinion; the pilot of the Mooney needs some refresher training and I recommend contact by FAA Investigator to determine if his pilot skills and knowledge have deteriorated to a point; that he needs a complete retest.
PA-28 Instructor pilot on short final is surprised by a M-20 overtaking from the left and landing ahead of him. A go around is initiated. After landing it was learned that the M20 pilot had attempted to land downwind on Runway 15 then went around; performing a 90/270 to come into conflict with the reporter. The wrong CTAF was also being used by the M20 pilot.
