I only had a few minutes at the hangar. I was picking up some tools I needed to work on some things at the EAA Chapter 54 clubhouse in Lake Elmo where I've just started a term as the "housing coordinator", an odd name for "janitor."
I looked around for the parts in the AOA kit and, yep, there they were right on the workbench. The discovery came just as I read that Van's has shipped $12 worth of the parts I'd just found. Just great! THAT order you fill right away but two single-lug platenuts are a bridge to far?
Anyway it turns out one of those parts -- a drill template ($3.50 at Van's!) - isn't needed as the hole is already drilled in the root rib (and every other rib) for the Angle of Attack. By the way, the instructions say to enlarge the hole using a step drill to 15/32" with nary an idea that there is NO 15/32" spot on a step drill. I'm sure the extra 1/32" won't be a problem.
A hard plastic piece needs to be cut and the soft plastic tubing is inserted into it 3/8". Then RTV is placed around the connection to seal it. So I did that.
Then I went to Lake Elmo
