Regarding the big F-16, my biggest concern is about the elevator system.

Here is a picture of the brass tube gluing area:



As you can see, the gluing of the elevator frame and load ribs is mostly dry. The whole fuselage section is flexible in this area.
I would strongly recommend every one to open up the speedbrake pods and re-do the brass tube and formers gluing.
I am additionally reinforcing this area of the fuselage with some carbon tapes and rows as well.

I also strongly recommend the owners of this big F-16 do drill the elevator at the rotation tube location and slide/glue in anti-rotation pins, as the gluing method of this tube has been very concerning in the past.
