Narrative

AS I APCHED JVL TO LAND I WAS ADVISED BY THE TWR THAT I WAS 4TH BEHIND SMA Z. I AM NOT THAT FAMILIAR WITH ALL Z MODELS AND ASSUMED THAT THE SMA Z WAS A TWIN. JUST AS I WAS ABOUT TO TURN ON FINAL; I HEARD THE TWR TALK TO AN SMT Y AND REALIZED THAT THIS WAS THE ACFT THAT I WAS FOLLOWING. I CALLED THE TWR AS I TURNED FINAL TO TELL THEM THAT I HAD BEEN FOLLOWING THE SMT AND DID NOT HAVE THE SMA Z IN SIGHT. AT THIS TIME I FINALLY SAW THE SMA Z ABOVE AND AHEAD OF ME. HE HAD BEEN ON A R BASE AND I WAS ON A L BASE SO WE WERE BOTH TRYING TO FOLLOW THE SMT Y. THE TWR ADVISED THE SMA Z TO TURN TO AVOID ME AND I CONTINUED ON FINAL AND LANDED. I THINK THAT I WILL TRY TO FAMILIARIZE MYSELF WITH MORE OF THE Z MODELS TO AVOID SUCH CONFUSION IN THE FUTURE. I ALSO FEEL THAT IF THE TWR HAD ADVISED TO FOLLOW A 'SINGLE ENG Z' RATHER THAN A PARTICULAR MODEL; I WOULD HAVE REALIZED MY MISTAKE SOONER AND WOULD HAVE BEEN LOOKING FOR THE CORRECT PLANE. I DO NOT FEEL THAT WE WERE CLOSE ENOUGH TO BE IN DANGER; BUT I AM SURE THERE WAS SOME FRUSTRATION/IRRITATION ON THE PART OF THE OTHER PLT.
