Doc control issues - warning about Ailerons
My paper plans drawing 14-5 is dated 7/24/14 and marked as Revision 1. It incorrectly calls out 4 rivets in those locations, as pointed out by the OP. The PDF plans, also labelled as revision 1, have a date of 12/31/03 marked on them, but correctly call out 8 rivets.
An even more amusing documentation control issue may be waiting for you in section 21 - Ailerons. Here, the entire section is a problem. My paper plans are marked "Revision 0" and dated 24 July '14. The parts I have (kit #41581) do not match the drawings. There is no steel bracket, for instance. The PDF plans for section 21 are marked "Revision 1" but the date is, interestingly, 24 Jul '12 - so according to the dates, the revision levels are counting backwards! However, the parts I have in the kit do indeed match the PDF plans.
I concluded that the date on my print set drawings is wrong, and that around 2012 after changing the Aileron design for the RV-14, Van's decided to update the RV-10 kit with the same design (since the 10/14 Ailerons are identical) but in so doing made a mess of the documentation control.
