Narrative

FLYING TO SANFORD ARPT I RPTED 7 MI OUT TO THE NE. SANFORD TWR INSTRUCTED ME TO RPT OVER OSTEEN BRIDGE (ABOUT 3 MI NE) FOR A L BASE FOR RWY 9L. DID SO OVER OSTEEN. I WAS THEN TOLD TO LOOK OUT FOR A SEMINOLE WHICH WAS ON XWIND AND INSTRUCTED TO FOLLOW HIM. I REPLIED THAT I HAD THE SEMINOLE IN SIGHT AND THAT I WOULD FOLLOW HIM. TWR THEN STARTED CALLING UP ALL PLANES IN THE PATTERN FOR RWY 9L AND ASKING THEM TO CONFIRM THEIR RELATIVE POS IN THE PATTERN. FOR SOME REASON TWR ASSUMED THAT I WAS STILL OVER OSTEEN BRIDGE AND I CORRECTED HIM AND TOLD HIM THAT I WAS ABEAM THE TWR. TWR RESPONDED BY HAVING ALL THE PLANES IN THE PATTERN FOR RWY 9L PERFORM A R 360 DEG TURN. THE SEMINOLE I WAS FOLLOWING WAS TOLD TO FOLLOW ME AND I WAS INSTRUCTED TO FOLLOW THE CESSNA AHEAD. HERE IS WHERE THE CONFUSION ON MY PART STARTED; SINCE THE ONLY CESSNA I COULD SEE WAS ON SHORT FINAL FOR RWY 9L. NEVERTHELESS I REPLIED AND COMPLIED BY TURNING BASE FOR RWY 9L. BY THIS TIME THE HVY (B767) WHICH WAS ALSO ON FINAL FOR RWY 9L BECAME VISIBLE (IN MY ESTIMATE HE WAS ON A 10 MI FINAL). THE SEMINOLE FOLLOWING ME WAS SO KIND TO QUERY TWR ABOUT MY TURNING BASE. WITH A SLIGHTLY HIGH PITCHED VOICE TWR TOLD ME TO TURN N NOW AND TO REJOIN THE PATTERN MID-FIELD DOWNWIND. HAVING TURNED N I WAS NOW ON A COLLISION COURSE WITH THE SEMINOLE WHICH WAS STILL FLYING WESTBOUND. THE SEMINOLE AVOIDED ME BY TURNING NW; I CONTINUED OUT FOR A FEW MINS AND THEN PROCEEDED EASTWARD TO REJOIN THE PATTERN MID-FIELD. THE TWR INSTRUCTED ME THEN TO FOLLOW THE SEMINOLE OFF MY L WING; 5 MI AWAY. I REPLIED THAT I WAS FLYING E AND THAT THERE WAS NO SEMINOLE OFF MY L WING. THE TWR CAME BACK TO ME AND TOLD ME TO REJOIN THE PATTERN ON THE DOWNWIND FOR RWY 9L. I LANDED SAFELY.
