Aileron Control Systems - Section 23

These are the bell crank to aileron push rods. Already powder coated by Vans, the threaded ends get drilled and installed with 2 long AN470D4-11 rivets sequentially squeezed to keep them from bending over.

The flap attachment arms shown with the bushings squeezed into place. This was accomplished with a C clamp and a socket on the back side. Ingenious and shown "how to do" this in the plans

Jury tubes after the jigging process ann drilling, ready for priming

This tubes are for the ailerons from the torque tube assembly to the aileron belcrank

All these tubes are being readied for priming the interior with AKZO. We tape one end, pour in the primer, let it sit for a minute or two, the pour it back in to the mixing cup.

Required supplies during the priming process

Allowing the push tubes to drain the primer into the trash. Most of it has already been drained back into the paint cup.

Torque tubes and push rods after completion

We still need to paint the ends of these push tubes the next time we pull out the primer

Today we installed and rigged the wing push rods. Vans sends a jig with the kit to lock the aileron bell crank and then you adjust the pushrods to set measurements noted in the plans. Nice, efficient and accurate, how can you beat that.

This is a shot of the aileron bell crank with the pushrods attached, torqued and marked with inspection lacquer.

This view is the pushrod that attaches to the aileron, with the length set during the rigging process while the aileron was in place. We tied it off to keep the pushrod from moving around.
