December 1, 2010 – Another component in the left leading edge I wanted to get to is the stall warning vane. This is a little vane that sticks out of the leading edge of the left wing that floats and makes a switch in the event of  a stall. It seems like not a lot of people have these installed, but I see no reason not to go ahead and install a simple piece of insurance. The left leading edge skin came drilled and cut out for it anyway, so I figured I may as well do it.

Since the skin had cutouts already, doing some of this work was pretty simple.

There’s an access panel on which I needed to drill the holes to #40. It will need to be dimpled and have nutplates installed.

I then had to cut out the slot that the vane will stick through. There were two small holes in the leading edge that I just had to enlarge, then cut out the material in between.

The rib that the switch attaches to goes right inside the leading edge. I put it in place and drilled the rivet holes to #40. I’ll dimple this rib and paint it when I do the rest of the leading edge ribs, and then I’ll install the guts of this thing later on.

This first picture is just the little rib that holds the switch, and the second picture shows the access panel with the rib towards the front.
