Since I’m putting Section 19 on “pause” until I get a pitot tube.....guess what? I started Section 20.
This first step in this section is to prepare the W-1021B Flap Gap Stiffeners. The Stiffeners come in one piece (shown below).....
and has to be separated into two individual Stiffeners as shown in the plans excerpt below.
After all the cutting, trimming, and sanding......here are the two individual Stiffeners. The four #40 holes on each Stiffeners were then final-drilled and dimpled and the edge work was completed.
Pictured below are the W-00011-L & -R Aileron Gap Fairings (the two shorter Fairings) and the W-00010-L & -R Flap Gap Fairings (the two longer Fairings). All four of these pieces needed the following work:
1. Deburr all the holes (#30’s and #40’s)
2.Dimple all the #40 holes
3. Dimple the six most inboard #30 holes on the Flap Gap Fairings
4. Clean the edges
All four steps listed above have been completed and they are ready for Alumiprep, Alodine, and Akzo Primer.
