Dynon AOA Retrofit?

[Rolly9]

Has anyone removed the Van's Al pitot tube and installed the Dynon AOA? How did you handle the hole where the AN fittings came through?

I had the same problem. Here's what I did:

(from memory--forgive the lack of AN numbers.)

First, I 'plugged' the hole with one standard washer (diameter just fits), then on the inside, I used a large 'bearing' washer. On the outside, I used a Tinnerman counterunk washer.

Then I bolted everything together with a flathead screw and nut.

This plugs the hole and gives a nice finished exterior appearance.

If this is not clear, I could take some photos, but I think if you play with it, you'll see what I mean.

Good luck!
