Beg to differ with you, but the only pull type rivet that the FAA bans in structural work is the old pop rivet. The Cherry Max rivet can be used as a straight substitute for a solid rivet provided it is not used in certain areas (ie. landing gear attach fittings, control mounts, wing and empennage attach fittings etc). If you want to read it for your self, go to http://faa.gov/ then type in AC43.13-1B on the search block, when that comes up, go to Chapter 4, then to section 4 and then to Para 4-53. You should find out more about riveting there than you really wanted to know.
