Page 21-04 - left and right seat rib assemblies
On page 21-04, I have to create these two seat rib assemblies using LP4-3 rivets. That does not seem right given that the rivets will be going through four parts - F-1215 (the seat rib), F-1017C-L, F-1017C-R (the seat belt attach lugs), and F-1216 (the seat belt attach lug support.) Seems to me it should be LP4-4's. I looked and there is no plan revision. Does this strike anybody else as odd or wrong?
