Wired Up Pitot Heater, Preping Left Wing for Closing – 4.5 hrs

Friday Nov 25, 2011

A long time ago I “finished” the wings without riveting the bottom skins because I was uncertain which EFIS I was going to install and which autopilot servos I would use, one of which installs in the wing. Well the time has come to mate the wings to the fuselage and the bottom skins need to be on for that so I need to wrap up the wing wiring and close’em up.

So today I finalized my planning for wiring in the wings and ordered wire and connectors from SteinAir for the Dynon autopilot servo. That will take a few days to arrive but in the mean time I could work on the left wing and the pitot heater wiring which I also left incomplete last winter. Here is what I came up with for routing. I installed a 3-pin Molex connector for the heater module and ran those wires down the wing to the root. I also looped the heater wires around and tagged them down to a rib using tie bases. It is pretty clean and there is plenty of clearance to the bellcrank.

Here is a view from the top so you can see the wiring routing better.

This next photo is the pitot tube and the plumbing routing.

I also decided to dimple all the holes in the bulkheads for the upper aft skins which I probably should have done weeks ago. So I took the upper skins off again.

And while I had such good access I finished installing the clips for the static line routing. These are now riveted in place. I left about 6 extra inches of static line tube to make sure I don’t come up short later.

And for fun I decided to cleco on the ribs that support the instrument panel. This is just checking things out. They will come back off again tonight.
