For the RV 7-9 fuselagae plans, drawing 19. for the rivets from F-601A-2 to F-601L-1 to WD-602-1, the callout is for AD436D4-6 rivets. What are these? Or is this just a typo, and they meant AD426 like everywhere else?
PRK, Just read my pre-plan book that was current as of 24 april 2007 and that drawing called for the AN 426d rivets. so yes yours is an older set witha typo!!
And I'm still amazed at how often the callout is too short. On the firewall there are tonnes of 3-3.5 that really should be 3-4s. I suspect sometimes for back-riveting they call for shorter rivets, because in my experience it's easier to cleat a rivet over badly when back-riveting. Anyway, i've found most of the callouts on the firewall are too short.. but some of them I've used the specified rivets anyway, because it was too difficult to back-rivet the longer ones without bending them.
