NMAC BTWN A VFR DEP BE23 AND A LNDG STEARMAN AT A NON TWR ARPT AT OCF; FL.

Narrative

I WAS DEPARTING OCF; A NON TWRED ARPT. UPON ENG START; AND WHILE COMPLETING MY POST START CHKLIST; I MONITORED THE CTAF. THERE WAS A CESSNA IN THE PATTERN IN CLOSED TFC. THERE WAS A PIPER AZTEC THAT STARTED UP AT ABOUT THE SAME TIME. THE AWOS INDICATED THE PREFERRED RWY WAS RWY 36. I TAXIED TO THE RUN-UP AREA OF RWY 36 WITH THE AZTEC FOLLOWING. WHEN AT THE RWY 36 RUN-UP AREA; THE WINDSOCK INDICATED THAT THE WIND HAD SWITCHED AND THE PREFERRED RWY WAS NOW RWY 18. I TURNED AROUND ON THE TXWY AND PROCEEDED TO RWY 18 AND THE AZTEC DID LIKEWISE. DURING TAXI; I CONTINUOUSLY MONITORED THE CTAF AND WATCHED THE DOWNWIND FOR TFC. THE ONLY ACFT IN THE PATTERN THAT I SAW AND HEARD WAS THE CESSNA IN CLOSED TFC. I COMPLETED MY RUN-UP; ANNOUNCED TAKING RWY 18 ON THE CTAF; AND CHKED THE PORTION OF THE DOWNWIND. I COULD SEE THE BASE LEG AND FINAL FOR TFC. SEEING AND HEARING NO OTHER TFC; I CROSSED THE HOLD SHORT LINE AND WHILE STILL LOOKING AT FINAL; I TOOK RWY 18. I DID NOT STOP ON THE RWY; BUT RATHER CONTINUED MY ROLL AND ACCELERATED ON THE CTRLINE OF RWY 18. I ROTATED AND AT ABOUT 50 FT AGL; I LOOKED TO MY R (W) AND SAW A BOEING STEARMAN OFF MY R WING ABOUT 75 FT AWAY. THE STEARMAN WAS PARALLELING THE RWY AND APPEARED TO BE IN LEVEL FLT AFTER SEVERAL SECONDS; THE STEARMAN TURNED W AND DISAPPEARED FROM MY SIGHT. I CALLED THE AZTEC AND ASKED WHERE THE STEARMAN CAME FROM AND THE AZTEC PLT COULD NOT TELL ME. THE STEARMAN WAS NOT TALKING ON THE RADIO; ASSUMING HE HAD A RADIO. I DO NOT KNOW HOW THIS COULD HAVE BEEN AVOIDED BY ME. I MONITORED THE CTAF; CHKED THE DOWNWIND; BASE AND FINAL FOR TFC BEFORE TAKING THE RWY. IT IS OBVIOUS THAT SOMETHING WAS NOT DONE RIGHT OR THIS EVENT WOULD HAVE NEVER HAPPENED. I BELIEVE IT IS POOR JUDGEMENT TO OPERATE ANY ACFT WITHOUT RADIO EQUIP OR FAIL TO MONITOR THAT EQUIP. I UNDERSTAND THAT RADIOS ARE NOT REQUIRED AT A NON TWRED ARPT AND THERE ARE MANY ACFT THAT ARE NOT RADIO EQUIPPED. THESE ACFT NEED TO STAY AWAY FROM BUSY ARPTS AND AIRSPACE. I DO NOT SEE HOW I COULD HAVE FAILED TO SEE THE STEARMAN IF HE HAD FLOWN A CONVENTIONAL DOWNWIND; BASE AND FINAL. MY ACTION OF TAKING THE RWY WHEN THERE WAS AN ACFT IN THE PATTERN SOMEWHERE AND UNKNOWN TO ME AND THE STEARMAN'S ACTION OF FLYING TO A BUSY NON TWRED ARPT WITHOUT A RADIO AND APPARENTLY FLYING UNCONVENTIONAL PATTERN WERE FACTORS.
