Vans refers to the mil-spec. MIL-R-47196A for riveting
guidelines. The FAA AC43.13's section on riveting spec is different.
Which is correct? Both?
Example for an 1/8" AN470-4: FAA says the shop head should
Be 1.5 the diameter min. And the min height as .5 the diam.
This is 3/16"(.1875) min diam of the shop head and 1/16" (.0625) for the min. height. (No max height)
Mil spec for the same rivet: shop head min diam: .163 and the height of
Min .050. And max .070
The mil spec is Army and DOT spec and different from FAA spec.
Why does Vans refer to the mil spec vs. FAA spec. Won't the DAR inspector
Be using FAA spec?
