PVT PLT OF SMA APCHS AND LANDS WRONG RWY.

Narrative

I WAS LNDG AT THE OHIO STATE ARPT ON OCT/XX/94 AT OPPORTUNITY XX30 PM IN THE AFTERNOON. I HAD CONTACTED THE TWR AND WAS GIVEN THE USUAL INSTRUCTIONS TO PROCEED TO THE INTXN OF THE SCIOTO RIVER AND THE OUTERBELT I-270; AND TO CONTACT THE TWR AGAIN WHEN REACHING THIS POINT. AND; FOR THE FIRST TIME EVER WHEN LNDG AT OSU; I WAS GIVEN A SQUAWK CODE WHICH DID CAUSE SOME CONFUSION OR I WAS NOT EXPECTING THIS. AFTER REACHING THE INTXN OF THE RIVER AND OUTERBELT I AGAIN CONTACTED THE TWR AND WAS ADVISED TO LAND ON WHAT I THOUGHT WAS RWY 9R WHICH IS THE PRIMARY RWY AT OSU. WITH WHAT I THOUGHT TO BE A CLRNC TO LAND; I PROCEEDED TO RWY 9R IN THE USUAL MANNER. I DO NOT RECALL ANY OTHER COM FROM THE TWR UNTIL I WAS ON VERY SHORT FINAL; AT THIS TIME I NOTICED THE SHADOW OF A PLANE WHICH WAS FLYING OVER THE TOP OF ME. I AM NOT SURE IT WAS CONSIDERED TO BE A NEAR MISS AS IT APPEARED THAT THERE WAS 200-300 FT BTWN THE 2 ACFT. ALSO AT THIS TIME THE TWR CAME BACK AND TOLD ME THAT I HAD BEEN CLRED FOR RWY 9L AND NOT RWY 9R. I LANDED WITHOUT INCIDENT; THE OTHER ACFT MADE A GAR AND ALSO LANDED WITHOUT ANY PROB. UPON SWITCHING TO THE GND FREQ; I WAS ADVISED TO CONTACT THE TWR BY PHONE WHICH I IMMEDIATELY DID. AT THIS POINT I AM STILL CONFUSED ABOUT WHAT HAPPENED. I HAVE MADE MANY LNDGS AT OSU AND UNDERSTAND THE TYPE OF TFC THAT REGULARLY INTO AND OUT OF THIS ARPT. I FEEL THAT I WAS MONITORING THE TWR FREQ IN THE USUAL MANNER AND TRYING TO UNDERSTAND WHAT WAS OCCURRING WITH OTHER TFC THAT DAY; ALTHOUGH I DO NOT RECALL HEARING COM WITH THE OTHER ACCESS INVOLVED IN THIS INCIDENT. IF I WAS GIVEN CLRNC IN RWY 9L; I MUST HAVE MISTAKEN THE CLRNC TO BE FOR RWY 9R WHICH IS THE USUAL PROC. HOW I MISUNDERSTOOD THE TWR INSTRUCTION IS SOMETHING I AM UNABLE TO EXPLAIN. THE ATIS RPT INDICATED RWY 9R IN USE; POSSIBLE AT THIS POINT. I JUST BECAME PROGRAMMED FOR THIS RWY.
