Narrative:

I was flying VFR en route. I was utilizing the current low altitude en route commercial chart dated may/xa/04. My route carried me over columbus west point (golden triangle regional) airport. On the chart commercial side, there is no mention of control tower frequency. Also on the chart it lists the CTAF as 122.8. As I approached the airport approximately 5 mi out, I was calling my position on 122.8. As I crossed midfield, the unicom said there is a tower and gave me the frequency. I then called the tower and he advised me that I had blown through his airspace without calling for clearance. This is the first time that I have found that the CTAF listed on face of the chart isn't accurate.
