Electrical

October 25, 2005

Tonight, I stopped by to carry on with wrapping things up in the Electrical department. First up was to wire the Nav antenna cable out to the wing root. This was pretty straight forward. See how much different the colour of the cable is! The lighter stuff seems to have faded, and the darker one hasn’t since it’s always been in a drawer. I still need to secure all these wires correctly. Currently, they’re temporarily tie wrapped into place.

Next task was to figure out the AOA flap switch mounting. Now this was a head scratcher. I really wanted it inthe centre of the plane, because I didn’t want wires running to the outside areas in any visible places. My baggage floors are already in, so I can’t go drilling new holes across the ribs under the floor. Eventually, I figured out that mounting the switch directly on the flap weldment would work out the best. Here, you can see how I mounted it with some No. 4-40 screws. I put an AN3 bolt in the rib in the tunnel which is adjustable for height to get the switch to actuate exactly where it needed to be. I also bent the end of the switch arm to make sure it always rides up over the bolt head. Seems to work a treat! Simple and effective.

Here’s another shot.
