Yesterday I was returning from my weekend trip when I almost had a head on collision at my home airport. I received the ASOS and it said winds were calm so I was planning on landing rwy 18. I cancelled my IFR flight with approach when I had the field in sight which was about 8 miles out. They told me to squawk VFR and that no traffic was in the area because I mentioned having trouble seeing because I was flying into the setting sun. I radioed for traffic and advisorys over the airports CTAF and got nothing. I proceeded to make a 5 mile, 3 mile, and short final call with no response to any of them. As I was crossing the threshold I saw a plane about 30-50ft higher flying at me and they continued overtop of me. I keyed the mic and said are you kidding me. I wasn't scared and didn't need to make any crazy aircraft control inputs because he was high enough and I was too low. I landed uneventfully and as I was taxing in he made a call he was turning downwind. I refrained from much conversation but I said I'm glad he is making radio calls now. He swore he was making calls and had a passenger to prove it. After landing I went and talked to the airport fuel operator who sits in a shack that monitors the CTAF. He said that he had left for coffee but he heard my short final call and my are you kidding me comment. I said thanks, and proceeded out to the fella to explain the importance of using the radio. I told him that the monitor heard me and either his radio wasn't on the correct freq or it wasn't on. Him and his passenger were a little shaken but didn't want to except any responsibility. So I then said I will make sure in the future to do an extensive runway check for aircraft and enter midfield downwind which will allow for better visibility with the setting sun. I asked that he double check his radios and left. While he wouldn't acknowledge any problems I hope he eventually understands how close this was and puts his ego aside. My point is that I'm happy to be alive and there are ways to make sure I keep myself out of this scenario again even if someone isn't talking on the radio. I know its not a requirement so like I said above keep a look out for that guy that might inadvertently do some airshow displays with you! I know I learned a valuable lesson I just hope the kid flying the other plane puts it in his tool bag as well! Be safe out there!
