Narrative:

Upon leaving the terminal tie-down area; I made the call on unicom stating my taxi intentions. While doing run-up on the taxiway near the approach end of runway 35; I monitored the unicom frequency and checked ASOS one more time. I also noted an aircraft in the pattern that apparently was not making calls or did not have a radio. It seemed logical; being a small crop duster type; that the plane did not have a radio and was not responding in any way. I failed to make a communication check to see if I was being heard. I then imputed the mcallister FSS and the center frequencys on communication #2. I looked around the pattern the best I could while facing east in a high wing airplane. I waited for the plane I had seen earlier to come into view on base; assuming he had not departed the pattern. A few moments later; I spotted the small plane where I had anticipated. I then called on the unicom my intentions to takeoff after the aircraft on base. When the plane touched down; I called a taxi to takeoff position and holding for departing traffic (he was doing touch-and-goes and was very slow; so I wanted to give him ample time). Approximately 10 seconds after I turned to face down the center of the runway; what I think was a beech bonanza flew over my aircraft for landing about at the 1000 ft markers of the runway. I fussed with the radios; my microphone cables and checked the frequency again. All was good and correct. I immediately called for a communication check. Hearing a very quiet response; I turned up the radio to hear an aircraft which had been taxiing to take off as well say that the departing aircraft had no radio. I said I heard nothing of an approaching plane; and could not see anyone else in the pattern. What must have been the landing aircraft radioed in response; 'I called all position.' in a somewhat quiet voice. This incident clearly would have been avoided if I had the radio turned up to a higher level. I would have been aware of the issue if I had done a communication check. I also may have noted an 'right' in the radio frequency window during any reception of another aircraft's calls. I also had made the assumption that the volume setting I had used for ASOS was adequate for unicom air traffic. It also bothers me that the aircraft landed at all. The aircraft was not on short final; and I simply could not see him. He could see me (or at least should have). The landing plane came in at 80 KTS or so; meaning he was at least 3/4 mi at my call that I was going to taxi to position.

Title: BONANZA LANDS OVER A C172 AT PNC.

Narrative: UPON LEAVING THE TERMINAL TIE-DOWN AREA; I MADE THE CALL ON UNICOM STATING MY TAXI INTENTIONS. WHILE DOING RUN-UP ON THE TXWY NEAR THE APCH END OF RWY 35; I MONITORED THE UNICOM FREQ AND CHKED ASOS ONE MORE TIME. I ALSO NOTED AN ACFT IN THE PATTERN THAT APPARENTLY WAS NOT MAKING CALLS OR DID NOT HAVE A RADIO. IT SEEMED LOGICAL; BEING A SMALL CROP DUSTER TYPE; THAT THE PLANE DID NOT HAVE A RADIO AND WAS NOT RESPONDING IN ANY WAY. I FAILED TO MAKE A COM CHK TO SEE IF I WAS BEING HEARD. I THEN IMPUTED THE MCALLISTER FSS AND THE CTR FREQS ON COM #2. I LOOKED AROUND THE PATTERN THE BEST I COULD WHILE FACING E IN A HIGH WING AIRPLANE. I WAITED FOR THE PLANE I HAD SEEN EARLIER TO COME INTO VIEW ON BASE; ASSUMING HE HAD NOT DEPARTED THE PATTERN. A FEW MOMENTS LATER; I SPOTTED THE SMALL PLANE WHERE I HAD ANTICIPATED. I THEN CALLED ON THE UNICOM MY INTENTIONS TO TKOF AFTER THE ACFT ON BASE. WHEN THE PLANE TOUCHED DOWN; I CALLED A TAXI TO TKOF POS AND HOLDING FOR DEPARTING TFC (HE WAS DOING TOUCH-AND-GOES AND WAS VERY SLOW; SO I WANTED TO GIVE HIM AMPLE TIME). APPROX 10 SECONDS AFTER I TURNED TO FACE DOWN THE CTR OF THE RWY; WHAT I THINK WAS A BEECH BONANZA FLEW OVER MY ACFT FOR LNDG ABOUT AT THE 1000 FT MARKERS OF THE RWY. I FUSSED WITH THE RADIOS; MY MIKE CABLES AND CHKED THE FREQ AGAIN. ALL WAS GOOD AND CORRECT. I IMMEDIATELY CALLED FOR A COM CHK. HEARING A VERY QUIET RESPONSE; I TURNED UP THE RADIO TO HEAR AN ACFT WHICH HAD BEEN TAXIING TO TAKE OFF AS WELL SAY THAT THE DEPARTING ACFT HAD NO RADIO. I SAID I HEARD NOTHING OF AN APCHING PLANE; AND COULD NOT SEE ANYONE ELSE IN THE PATTERN. WHAT MUST HAVE BEEN THE LNDG ACFT RADIOED IN RESPONSE; 'I CALLED ALL POS.' IN A SOMEWHAT QUIET VOICE. THIS INCIDENT CLRLY WOULD HAVE BEEN AVOIDED IF I HAD THE RADIO TURNED UP TO A HIGHER LEVEL. I WOULD HAVE BEEN AWARE OF THE ISSUE IF I HAD DONE A COM CHK. I ALSO MAY HAVE NOTED AN 'R' IN THE RADIO FREQ WINDOW DURING ANY RECEPTION OF ANOTHER ACFT'S CALLS. I ALSO HAD MADE THE ASSUMPTION THAT THE VOLUME SETTING I HAD USED FOR ASOS WAS ADEQUATE FOR UNICOM AIR TFC. IT ALSO BOTHERS ME THAT THE ACFT LANDED AT ALL. THE ACFT WAS NOT ON SHORT FINAL; AND I SIMPLY COULD NOT SEE HIM. HE COULD SEE ME (OR AT LEAST SHOULD HAVE). THE LNDG PLANE CAME IN AT 80 KTS OR SO; MEANING HE WAS AT LEAST 3/4 MI AT MY CALL THAT I WAS GOING TO TAXI TO POS.
