A lot of planes are riveted. I almost bothered to figured the strength of the joint, and I'm sure it's fine, but that's what VW thought when it replaced bolts in the ring gears of their five speed transmissions to save a few bucks, and then watched their trannys come unglued one at a time when the rivets failed. My 16V Scirroco was one of them, and I had to weld up the trans case after one of those rivets punched a hole in it. That involved a total teardown of the transmission, so it made an impression on me. The "cure" was bolts and nuts. Call it personal preference if you will, but mine are welded 4130. By the same token, RR's aileron pushrod is something like quarter inch aluminum rod threaded on both ends for heim joints, but then it's only about 4" long....
