Title: Pitot plumbing
Kid #2 helped me put the r/h wing on the wing stand. Once that was done, I went back to the L/H wing and worked on plumbing for pitot and AOA. I don't like the idea of that nylon tubing with its heavy press-on fittings just flopping around where in connects to the 3/16"alum. tube coming off the pitot tube. Seems like it might be hard on the pitot hard lines, plus its right under the aileron push tube so I definitely don't want stuff flopping around in there. Also people have told me that they've had a lot of trouble with those fittings leaking and it would sure be nice to have easy access during pitot/static checks. To that end, I've broken my own rule about less fittings is better. I fabricated and installed a 24" length of 1/4" AN tube from the pitot bay to the inbd inspection bay for both the pitot and AOA. The plan is to connect the pitot lines via a union, then on the other end transitioning to the nylon where its easy to get to. Will see how this works during system wring out, but worst case scenario is that if it leaks I can go back to plan A and run nylon all the way to the pitot bay.
