The strength of a NAS 1097 is easily found. And where would you used 2" rivet spacing? Are you a structural engineer?

........2" spacing when attaching a stiffener to a fuse skin; on a doubler for an inspection plate are two examples...... with a NAS1097, no I'd not personally use those for these cases, at least not repeatedly. To get out of a jam, yeah one or two. Pretty much 99% of the time however, I use -3 1097s for nutplate installs....

Being from the part 121 world when building my 7 those big head rivets looked clunky to me. Oh well, I'm a firm believer in doing what a much more qualified person than me engineered. Substitutions should not be taken lightly in primary structure areas.
Funny thing is that when at Braniff confronted with a non routine repair we would often use our experience to formulate a repair then call engineering who would do a structural analysis and approve the repair and draft drawings to match it. The engineers at Braniff were much more available in those days, at Northrop they hid, and you had to know the secret knock to get into their lair.
