Narrative:

I was approaching an uncontrolled airport from the south. I began calling unicom approximately 8-10 mi out for landing runway and traffic. After repeated calls I received no replies from either unicom or traffic in the area. I could hear traffic at other airports considerable distances away. I elected to fly over the field above pattern altitude to check landing direction and traffic. I called overhead the airport, turning downwind, base and final for a low pass. At no time did I hear any other traffic call in the pattern or any call from unicom. Passing down the right (east) edge of the runway, I saw a grey C-150 going the opposite direction (south) sidestepped west of the runway. The wind was light, but the windsock was hanging south of the pole indicating a north landing. I was going north the C-150 was going south. After we both landed, I found that the C-150 was a student pilot and was using the south landing pattern because with light and variable winds the field local knowledge is to land and takeoff south because it's a more convenient taxi. The student said that he heard my calls but didn't see me before we both turned opposite finals. The instructor and office guy said that they didn't hear any of my calls. But when I made a test call it was loud and clear. Had the operator manned the unicom this would not have happened. Had the student made some more emphatic calls or any calls at all I would have known he was there.

Title: NMAC OCCURRED WHEN 2 ACFT APCHED THE RWY FROM OPPOSITE DIRECTIONS AT AN UNCTLED ARPT.

Narrative: I WAS APCHING AN UNCTLED ARPT FROM THE S. I BEGAN CALLING UNICOM APPROX 8-10 MI OUT FOR LNDG RWY AND TFC. AFTER REPEATED CALLS I RECEIVED NO REPLIES FROM EITHER UNICOM OR TFC IN THE AREA. I COULD HEAR TFC AT OTHER ARPTS CONSIDERABLE DISTANCES AWAY. I ELECTED TO FLY OVER THE FIELD ABOVE PATTERN ALT TO CHK LNDG DIRECTION AND TFC. I CALLED OVERHEAD THE ARPT, TURNING DOWNWIND, BASE AND FINAL FOR A LOW PASS. AT NO TIME DID I HEAR ANY OTHER TFC CALL IN THE PATTERN OR ANY CALL FROM UNICOM. PASSING DOWN THE R (E) EDGE OF THE RWY, I SAW A GREY C-150 GOING THE OPPOSITE DIRECTION (S) SIDESTEPPED W OF THE RWY. THE WIND WAS LIGHT, BUT THE WINDSOCK WAS HANGING S OF THE POLE INDICATING A N LNDG. I WAS GOING N THE C-150 WAS GOING S. AFTER WE BOTH LANDED, I FOUND THAT THE C-150 WAS A STUDENT PLT AND WAS USING THE S LNDG PATTERN BECAUSE WITH LIGHT AND VARIABLE WINDS THE FIELD LCL KNOWLEDGE IS TO LAND AND TKOF S BECAUSE IT'S A MORE CONVENIENT TAXI. THE STUDENT SAID THAT HE HEARD MY CALLS BUT DIDN'T SEE ME BEFORE WE BOTH TURNED OPPOSITE FINALS. THE INSTRUCTOR AND OFFICE GUY SAID THAT THEY DIDN'T HEAR ANY OF MY CALLS. BUT WHEN I MADE A TEST CALL IT WAS LOUD AND CLR. HAD THE OPERATOR MANNED THE UNICOM THIS WOULD NOT HAVE HAPPENED. HAD THE STUDENT MADE SOME MORE EMPHATIC CALLS OR ANY CALLS AT ALL I WOULD HAVE KNOWN HE WAS THERE.
