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....
