This is because the author of the ac3d-export script made a conscious decision not to export 2 sided Blender surfaces as 2 sided .ac surfaces. The reason is that all the surfaces in Blender are 2 sided by default and this would result in either a lot of work for modelers or something close to a doubling of the polygon count for a model. The solution for modelers is to simply duplicate the surface that you want to be two sided and then flip normals. Personally, I almost never do this since zero thickness surfaces just don't occur in real life. I also use shrink/fatten on one of the surfaces to give the object some thickness.
