I have a typical sail cloth over aluminum tube structure ultralight that has quite a bit of "slop" in all the bolted members. AC43.13 stipulates much closer fit than this structure exhibits. But I've been told several conflicting things about bolt clearances on part 103 or similar structure LSA. i have no prior experience with this type of aircraft structure. All my previous Plane projects have been in wood with 4130 bolt on fittings etc. or helping others with their all aluminum monocoque structures. Any one that can give me the scoop on proper safe bolt hole clearances in such structures, I would be very appreciative.
