Narrative:

I had entered the pattern and was on downwind for runway 31. There were several other aircraft in the pattern and I heard 2 planes calling final, one extended. I continued in the pattern looking for traffic and told my kids (passenger) to watch for other airplanes. As I approached the base leg, I heard a plane call short final. I idented that plane, high wing, and looked for a second plane. I did not see one and thought I missed the first one on final, due to the amount of time going by. I called base and then called final. As I leveled off on final, I heard a piper arrow come over the radio and say 'nice job cherokee, I was already on final!' I landed and taxied to my parking spot. A piper arrow taxied in near me a few mins later. I approached the pilot and asked if I had cut him off on final. He told me that I had and he was forced to take evasive action. He asked if I had heard him on final and said that he had called the pattern as he came in. I apologized and told him that I had heard the 2 planes on final and thought he was the second one. I did not see another plane on final, so I turned base and then final. He told me that he was slightly below me and I had turned final right in front of him. He said that he was probably in my blind spot under the wing as I turned and he was forced to turn right and descend quickly. I told him that I never saw him or heard him until he called out 'nice job.' I apologized again, shook hands and we parted ways. I was telling my kids to help me watch for other planes and was distraction. If the other pilot had not said anything, I would not have known anything had happened. The other plane was apparently in the blind spot of my right wing. To help minimize problems, I could have called on CTAF to verify that the plane I saw on short final was in fact the second plane on final, or I could have dipped my right wing slightly while on base to ensure nothing was under me or in the blind spot as I turned onto final.

Title: A PA28 SINGLE PLT CUT OFF ANOTHER PA28 ON FINAL FOR RWY 31 AT WDR.

Narrative: I HAD ENTERED THE PATTERN AND WAS ON DOWNWIND FOR RWY 31. THERE WERE SEVERAL OTHER ACFT IN THE PATTERN AND I HEARD 2 PLANES CALLING FINAL, ONE EXTENDED. I CONTINUED IN THE PATTERN LOOKING FOR TFC AND TOLD MY KIDS (PAX) TO WATCH FOR OTHER AIRPLANES. AS I APCHED THE BASE LEG, I HEARD A PLANE CALL SHORT FINAL. I IDENTED THAT PLANE, HIGH WING, AND LOOKED FOR A SECOND PLANE. I DID NOT SEE ONE AND THOUGHT I MISSED THE FIRST ONE ON FINAL, DUE TO THE AMOUNT OF TIME GOING BY. I CALLED BASE AND THEN CALLED FINAL. AS I LEVELED OFF ON FINAL, I HEARD A PIPER ARROW COME OVER THE RADIO AND SAY 'NICE JOB CHEROKEE, I WAS ALREADY ON FINAL!' I LANDED AND TAXIED TO MY PARKING SPOT. A PIPER ARROW TAXIED IN NEAR ME A FEW MINS LATER. I APCHED THE PLT AND ASKED IF I HAD CUT HIM OFF ON FINAL. HE TOLD ME THAT I HAD AND HE WAS FORCED TO TAKE EVASIVE ACTION. HE ASKED IF I HAD HEARD HIM ON FINAL AND SAID THAT HE HAD CALLED THE PATTERN AS HE CAME IN. I APOLOGIZED AND TOLD HIM THAT I HAD HEARD THE 2 PLANES ON FINAL AND THOUGHT HE WAS THE SECOND ONE. I DID NOT SEE ANOTHER PLANE ON FINAL, SO I TURNED BASE AND THEN FINAL. HE TOLD ME THAT HE WAS SLIGHTLY BELOW ME AND I HAD TURNED FINAL RIGHT IN FRONT OF HIM. HE SAID THAT HE WAS PROBABLY IN MY BLIND SPOT UNDER THE WING AS I TURNED AND HE WAS FORCED TO TURN R AND DSND QUICKLY. I TOLD HIM THAT I NEVER SAW HIM OR HEARD HIM UNTIL HE CALLED OUT 'NICE JOB.' I APOLOGIZED AGAIN, SHOOK HANDS AND WE PARTED WAYS. I WAS TELLING MY KIDS TO HELP ME WATCH FOR OTHER PLANES AND WAS DISTR. IF THE OTHER PLT HAD NOT SAID ANYTHING, I WOULD NOT HAVE KNOWN ANYTHING HAD HAPPENED. THE OTHER PLANE WAS APPARENTLY IN THE BLIND SPOT OF MY R WING. TO HELP MINIMIZE PROBS, I COULD HAVE CALLED ON CTAF TO VERIFY THAT THE PLANE I SAW ON SHORT FINAL WAS IN FACT THE SECOND PLANE ON FINAL, OR I COULD HAVE DIPPED MY R WING SLIGHTLY WHILE ON BASE TO ENSURE NOTHING WAS UNDER ME OR IN THE BLIND SPOT AS I TURNED ONTO FINAL.
