Yup, that's on my sheet 23 too. Mine are dated the same. Thing is, that my sheet 21 and 22 (of the same date) show only one row of rivets (and different rivet spacing in other areas). And my plane seems to have been built in accordance to these sheets 21 and 22, and thus in contradiction with sheet 23. My question was basically: was the builder a renegade moron who cut corners? Answer: no, he just stuck to sheets 21 and 22 (or perhaps an older version of the plans).

I don't feel the need to rebuild half of my fuselage now. There are more aircraft flying around with a single row of rivets there, and they are not falling out of the sky left and right.

Still, it is interesting how conflicting versions of something this fundamental have found their way in the same set of drawings, dated on the same day.

The front area of the seat pan has integral steps. On my plane I misinterpreted that detail and cut the seat pan so that the steps are separate pieces. (EDIT - the steps are supposed to be separate, see other postings below, so I accidentally got it right!) This is the area on Dwg 24 that shows this.

The drawing indicates that the spar bulkhead flange goes from side to side. It doesn't, at least on the RV-3B. Here's that area on my plane. The photo was taken prior to adding the steps.

On both pictures, forward is to the left and top is the right side of the plane.

Incidentally, the rudder cable runs directly over the forward outboard screw on the steps. Bit of a pain there.

Just something to be aware of so that you don't need separate parts for the steps.

Dave, I think the steps are separate, my interpretation of the plans is that the seat pan is 025 2024-T3 and fixed with LP 4-3 pulled rivets and the steps are 062 6061-T3 with 3/4x3/4x1/8 angle supports. The steps are fixed with screws and nut plates, 10 per side removable.
At least that's how I did mine, I could be wrong...

On my -3B, the main floor pan skin is riveted on, and the remainder is closed out by three removable sections. Two smaller reinforced step sections to the sides, and a central cover over the stick.

I don’t think there are any two -3’s alike in this area - I built a two-piece close out that covers most of the stick opening and also provides the steps.

Default Manual Trim Cable Routing

It seems as if the manual trim cable should enter the cockpit above the rudder cable. That wasn't obvious to me and I arranged to have it enter below. Now things are clearer. My fuselage is slightly lighter with some additional cable holes in the seat and baggage bulkheads.

Keep the manual trim cable above the rudder cable.
