I have read AC-43 and they suggest a doubler tied into the aircraft structure for supporting antennas, or at least that is how I read it. To tie a doubler between floor ribs in the -8 this would entail riveting out already installed rivets to make a doubler to tie between the two floor ribs. Now for the most part drilling out a rivet is fairly easy but there are the few times if can become a mess. Do I really need to do this or would a doubler just riveted to the floor do the job just fine. My thought is a rectangle 2 inches larger than the area the antenna base takes up with two bends to form a stiffening flange.
I am not sure drilling out rivets in the floor ribs is a good idea. Thanks for any help. If you have done it the way I suggest and are flying please let me know how it has worked out and if you would do anything differently.
