Narrative:

While doing touch-and-go working ('towards tailwheel endorsement') with CFI, entered left downwind runway 15. A cessna (forgot call sign) announced right downwind runway 15. Lna is left traffic. The cessna announced right base, I announced left base. He announced final but was a long way out (2 mi approximately). My instructor was initiated and put the plane on final (1/4 mi out at most -- piper cubs turn on a dime). I announced final (no electrical system and I had the handheld radio). The cessna pilot said to the effect 'wait, I am on final' to which I said 'well, we are no factor for you' (which we weren't) plus 'you are causing problems by not flying l-hand traffic.' btw unicom told the cessna on his initial call that runway 15 was 'active, l-hand traffic.' we both landed without a problem. I was caught between a rock and a hard place. If it had been up to me I would have dropped in and turned final behind the errant cessna. But, the CFI had taken the controls and I didn't think it worth wrestling over. Although in violation of 91.113(G), we were not a factor for the cessna, so I just announced our position. My comment on the radio regarding the cessna flying r-hand traffic was inappropriate. In the future I will 1) avoid temptation to tell other pilots their errors on unicom no matter how tempting, and 2) not turn in front of someone on final -- even if there is plenty of room to do so. Too risky! 3) remember what mom always said: 'two wrongs, don't make a right!'

Title: A PIPER CUB CFI CUTS OFF A CESSNA ON FINAL BECAUSE THE CESSNA HAD ENTERED THE TFC PATTERN FROM THE WRONG SIDE, R TFC VERSUS L TFC.

Narrative: WHILE DOING TOUCH-AND-GO WORKING ('TOWARDS TAILWHEEL ENDORSEMENT') WITH CFI, ENTERED L DOWNWIND RWY 15. A CESSNA (FORGOT CALL SIGN) ANNOUNCED R DOWNWIND RWY 15. LNA IS L TFC. THE CESSNA ANNOUNCED R BASE, I ANNOUNCED L BASE. HE ANNOUNCED FINAL BUT WAS A LONG WAY OUT (2 MI APPROX). MY INSTRUCTOR WAS INITIATED AND PUT THE PLANE ON FINAL (1/4 MI OUT AT MOST -- PIPER CUBS TURN ON A DIME). I ANNOUNCED FINAL (NO ELECTRICAL SYS AND I HAD THE HANDHELD RADIO). THE CESSNA PLT SAID TO THE EFFECT 'WAIT, I AM ON FINAL' TO WHICH I SAID 'WELL, WE ARE NO FACTOR FOR YOU' (WHICH WE WEREN'T) PLUS 'YOU ARE CAUSING PROBS BY NOT FLYING L-HAND TFC.' BTW UNICOM TOLD THE CESSNA ON HIS INITIAL CALL THAT RWY 15 WAS 'ACTIVE, L-HAND TFC.' WE BOTH LANDED WITHOUT A PROB. I WAS CAUGHT BTWN A ROCK AND A HARD PLACE. IF IT HAD BEEN UP TO ME I WOULD HAVE DROPPED IN AND TURNED FINAL BEHIND THE ERRANT CESSNA. BUT, THE CFI HAD TAKEN THE CTLS AND I DIDN'T THINK IT WORTH WRESTLING OVER. ALTHOUGH IN VIOLATION OF 91.113(G), WE WERE NOT A FACTOR FOR THE CESSNA, SO I JUST ANNOUNCED OUR POS. MY COMMENT ON THE RADIO REGARDING THE CESSNA FLYING R-HAND TFC WAS INAPPROPRIATE. IN THE FUTURE I WILL 1) AVOID TEMPTATION TO TELL OTHER PLTS THEIR ERRORS ON UNICOM NO MATTER HOW TEMPTING, AND 2) NOT TURN IN FRONT OF SOMEONE ON FINAL -- EVEN IF THERE IS PLENTY OF ROOM TO DO SO. TOO RISKY! 3) REMEMBER WHAT MOM ALWAYS SAID: 'TWO WRONGS, DON'T MAKE A RIGHT!'
