Before You Start

Special/New Tools/Supplies

• You will need to build some wooden support braces (see page 8-7, step 5).

Notes

• Step 5: The manufactured head of the rivets attaching the doubler to the rear spar go onto the spar side to reduce the likelihood of interference with the elevator leading edge.

• Step 3: The 1 21/32 lower flange width dimension is to be applied at the 1 inch line, not at 2 inches, the raw angle size.

• Step 1: Place the manufactured heads of the rivets common to the doubler and the spar on the spar. This ensures the rivet orientation is consistent with the instructions later on page 8-13, figure 1.

Also recall the general rule: Manufactured head on the thicker material.

• Step 3: only cut back the two corners on the front edge of the nose rib, not the entire edge because then you will violate the edge distance for the foremost rivet. See also this FB thread.
• Step 4: Very likely that the nose rib that came with a recent kit already has the holes in the web that step 4 calls out for making

• Please read the notes in figure 1, they spell out that all the manufactured heads are on the outside (rear) of the spar. This helps with avoiding elevator leading edge binding.
