My reference to the bonding issues was partly an awareness point, as other posters have also mentioned. However, in addition, even a bonded aircraft which is in good condition may need to be repaired one day. The AA1 and AA5 designs were born of Jim Bede amateur build designs, which were intended to be quick and simple to build and maintain. That simplicity can turn itself back around decades later into costly complexity, if the maintenance facility is not set up for that kind of work. Simply satisfy yourself that were the aircraft to be damaged, getting it fixed is easily accomplished - denting a leading edge is easy, replacing several whole wing panels can be more that expected in cost, time, and parts.
