WIX-T07 tail mount issues

[Bryan Cotton]

I have submitted this to tech support, but am sharing anyway.

With my stabilators clecoed in position in the back, they appear to fit nicely. So I slide my WIX-T09-04 lower attach angle in place, after I radius it for the bend in the hockey stick:


I use a red sharpie to mark where the hole will go for the AN4-17A bolt, using the 3/32" pilot in my lower attach angle. I have the machined angle parts. I have also drawn a blue line colinear with the row of rivets that go through the WIX-F22-02 aft shear web and WIX-F22-06 angle. The rivets are nicely centered on the angle. The red line, which marks the hole I will bore through the longeron is forward of the row of rivets by 3/16".


Here is a picture under the WIX-F22-06 angle. If the 1/4" hole is forward of the rivet line by 3/16" I will have poor edge distance, just over 1D:


Anybody else seen this?

I had the same issue, and ended up putting a 1/8" x 1" spacer between the hockey stick and lower attach angle, which put the lower attach angle into a better position for the bolt holes. This was approved by Kerry at Sonex.

I remade my F22-06 angle with a long flange.

New one is in the back.
