Narrative:

I hadn't flown my ultralight (based at chandler airport) in about 9 months. I flew east from chandler to the east end of the valley and skirted my way around williams on my way east. I wanted to land at williams with my ultralight since the last time I landed there had been 24 yrs earlier when I graduated from williams AFB. I knew the military base had been closed for 1 1/2 yrs. I also checked a frequency chart at chandler airport, and it listed williams municipal as uncontrolled with a unicom (122.4). My mistake was not looking further to the other side of the frequency chart. There I would have found williams gateway which is what the old williams AFB is now called. The williams municipal uncontrolled field refers to the williams airport at williams in northern arizona. A name change for one or the other might help in the future. I should have asked and not assumed about williams AFB being still shut down. When I flew past the airport and when I came back again there was absolutely no activity whatsoever on the ramp or in the air nor was there any lights from the tower. I did 2 touch and goes to the center runway, flew past the tower, and then returned to chandler airport. Upon landing the airport manager told me my transgressions and to call williams gateway tower which I did to explain myself, apologize, and promise never to do it again.
