I'm working on Section 10 of my empennage kit (rear fuselage). On page 10-7 it refers to optional #27 dimples for a couple holes. I spent half an hour scouring the plans to figure out what this option is.
I think I found it on page 10-32. You apparently just replace the kit provided round head AN526-632R8 screws with optional AN507-632R8 flush screws as shown below.
My question-
Why are these screws optional??? Why would I not want flush screws? I thought Vans would always opt for a flush screw (and flush rivets) if possible.
