I began closing up my left wing aileron this evening and after I triumphantly set all 45 rivets that secure the upper skin to the spar, I flipped the aileron over to install the bottom skin and found that I had missed setting some of the rivets that hold the nose skin to the ribs. Specifically, the five AN426 rivets that hold the skin to the outboard and inboard ribs on the bottom. I had apparently set the ones on the middle rib but missed the outboard and inboard.
There is no way I can access these to set these nose rivets short of drilling out all 45 top skin rivets and the 9 pulled rivets that hold the spar to the nose ribs.
I am trying to decide whether there is an acceptable pulled rivet that can be placed in the spaces I have missed. I know the forward most two rib rivets on the top nose skin are pulled rivets (I pulled those already) and wonder if the MK-319-BS rivets used there can also be used on the bottoms inboard and outboard ribs. From what I have found on those rivets, they have a shear strength of 258 lbf and a tensile strength of 292 lbf (source: http://fasteners.oemfast.com/item/all-categories/pop-open-end-rivets/md319bs). The shear number is comparable favorably to an AN426AD3 rivet but I think the tensile strength falls short?
Any ideas? I really don't want to have to drill out all these rivets if it's not necessary.
