On the Quickbuild RV-7/7A Fuse you still have to install the AN470AD4 Rivets in the upper right and left corners of the F-705 bulkhead assembly because of the differences between the tip-up and sliding canopy. Because Van's has assembled most of the metalwork in this area (including the skin) riveting the F-705F top channel to the F-705D & F-705E side channel/doubler is quite difficult. After a misdrill on a rivet removal I now have a hole thats way too big for a AD4 rivet.
Because of the tightness of the area, I would really prefer to open the hole to 5/32 and use a NAS623 structural screw instead of the rivet, because there just is not the room for easy riveting here. Is this a big no-no? Would I have to worry about Steel/Aluminum Corrosion if I did?
