Here is an extreme closeup of the leading edge of the wing where the normals are bad. Notice that some of the faces have two or even three normals poking out. That is because the normals from the top of the wing are good, but some of the normals from the bottom of the wing are pointing up (going through the inside first) and then coming out the top. Notice the blue dots on some of the faces. Those are where the normal is starting inside instead of outside. I think part of what is confusing you is that the selection color makes everything kind of look brown like the bottom of the wing is colored.
