Revision 1 to section 7 (rudder) has a change on page 07-11. In the added step 5 and Figure 1 it has you final drill #33 the aft-most 6 holes in R-903 - the rudder tip rib. The current holes which I have already final drilled and dimpled per the plans are #40 to match the skin and the rivet call outs on page 7-12, figure 2.
So...what gives? The rivet callout is for a 426AD-3-3 which is a little small for a #33 hole. What did all you smart people do here?
Also, what did you use to get inside the aft part of that tip rib to squeeze those rivets? That's a mighty tight fit!
