Narrative:

I was traveling from south to north and had made a radio statement that I would be overflying the airport on the west end of the runway 24 at 1100 ft. There was no response on the radio, and I assumed this was due to them being busy at something else. Upon reaching the runway, I observed a plane rotating for takeoff. I still did not consider this a problem, because the plane should have no trouble passing under me. When I tried to make another statement on the radio, I realized that my transmit select switch was on the wrong radio. When I came upon the proper frequency, I was in contact with an angry, cursing pilot, who vowed to have me violated. He said that he had to lower the nose of his aircraft to avoid a collision. I was distraction by my passenger, and failed to make certain that I was on the proper radio, but I did not feel that I was in violation of any particular rule by not making radio contact at an uncontrolled field. I never felt threatened and took no corrective actions. The other pilot said he had to reduce his rate of climb. I was at 900 ft AGL. The other pilot called and complained to my employer. He stated that he did not see me until the last few seconds, because he was on an instrument flight plan, and he was 'on the gauges.' I feel this situation could have been prevented if I had been more certain about my radio procedures and if the other pilot had been more observant to the outside on a takeoff under VFR conditions at an uncontrolled field. I am still unable to find any far that I violated, but it was an undesirable situation, and a near midair collision report has been filed by the other pilot. All of this occurred around XA30 over ili on sep/fri/03.

Title: PVT ACFT HAS NMAC AT NON TWRED ARPT.

Narrative: I WAS TRAVELING FROM S TO N AND HAD MADE A RADIO STATEMENT THAT I WOULD BE OVERFLYING THE ARPT ON THE W END OF THE RWY 24 AT 1100 FT. THERE WAS NO RESPONSE ON THE RADIO, AND I ASSUMED THIS WAS DUE TO THEM BEING BUSY AT SOMETHING ELSE. UPON REACHING THE RWY, I OBSERVED A PLANE ROTATING FOR TKOF. I STILL DID NOT CONSIDER THIS A PROB, BECAUSE THE PLANE SHOULD HAVE NO TROUBLE PASSING UNDER ME. WHEN I TRIED TO MAKE ANOTHER STATEMENT ON THE RADIO, I REALIZED THAT MY XMIT SELECT SWITCH WAS ON THE WRONG RADIO. WHEN I CAME UPON THE PROPER FREQ, I WAS IN CONTACT WITH AN ANGRY, CURSING PLT, WHO VOWED TO HAVE ME VIOLATED. HE SAID THAT HE HAD TO LOWER THE NOSE OF HIS ACFT TO AVOID A COLLISION. I WAS DISTR BY MY PAX, AND FAILED TO MAKE CERTAIN THAT I WAS ON THE PROPER RADIO, BUT I DID NOT FEEL THAT I WAS IN VIOLATION OF ANY PARTICULAR RULE BY NOT MAKING RADIO CONTACT AT AN UNCTLED FIELD. I NEVER FELT THREATENED AND TOOK NO CORRECTIVE ACTIONS. THE OTHER PLT SAID HE HAD TO REDUCE HIS RATE OF CLB. I WAS AT 900 FT AGL. THE OTHER PLT CALLED AND COMPLAINED TO MY EMPLOYER. HE STATED THAT HE DID NOT SEE ME UNTIL THE LAST FEW SECONDS, BECAUSE HE WAS ON AN INST FLT PLAN, AND HE WAS 'ON THE GAUGES.' I FEEL THIS SIT COULD HAVE BEEN PREVENTED IF I HAD BEEN MORE CERTAIN ABOUT MY RADIO PROCS AND IF THE OTHER PLT HAD BEEN MORE OBSERVANT TO THE OUTSIDE ON A TKOF UNDER VFR CONDITIONS AT AN UNCTLED FIELD. I AM STILL UNABLE TO FIND ANY FAR THAT I VIOLATED, BUT IT WAS AN UNDESIRABLE SIT, AND A NMAC RPT HAS BEEN FILED BY THE OTHER PLT. ALL OF THIS OCCURRED AROUND XA30 OVER ILI ON SEP/FRI/03.
