I made a stupid mistake today while countersinking the W-00002 wing inboard top skin that sits on top of the wing walk doublers on page 16-02. There are three rows of holes that I countersunk rather than dimpled as shown below. The top or forward row attaches to the main wing spar. The holes in the wing spar where the top skin attaches are countersunk. The middle row of holes attaches to the W-00009B J-Stiffener underneath which are supposed to get dimpled in a later step. The bottom (aft) row of holes attaches to the rear spar which is also dimpled.
This mistake stings even though I'm way overdue for a mistake. I'm guessing I could forgo the dimpling on the J-Stiffener and all would be good for the middle row of countersunk holes that I screwed up. I could then "un-dimple" the rear spar holes and that would be OK as well. But, the main spar under the top row of holes is countersunk. No way to "fix" that.
So, do I need to replace this top skin? And yes, I plan to ask Vans but it will be hard to sleep on this one until I can get in touch with them next week. Just curious what you folks think.
