I final-drilled the wing root fairing stiffeners:

I had hoped to use the TCW tech fittings for the fuel line exit hole, but detected that it'll cause interference with the lower wing fairing root support, so another solution will be needed (which may mean trimming both the fitting and the root support a bit):

I also trimmed the flap pushrods to the desired length, but that takes some tuning after the wings are on, so I can't finish it yet.
With this, the rest of the section has to wait until I'm ready to attach the wings, much later.
Total wing attachment time: 4.5h
