Builders,
We recently noticed that several important rivet holes may be missing on your wing skins.
Please see the photo for the layout of the rivets.
They are in the leading edge skin at the inboard end. These must be on top and bottom of both wings. Please verify if your skins have these holes, and if not you must add them. If you are using flush rivets and have already riveted you wings completely it will be impossible to counter sink the spar and dimple skins. You will need to use protruding head rivets for these holes.
If you have any questions, please contact us.
