Default Is this a problem?

I just pulled one of the wings off "Dusty" and the rear spar has been misdrilled. The attach point where it attaches to the fuse has a small hole next to it. See pic. Anybody know how I could fix this or is it a problem?

I would refer that to the Van's engineering department for evaluation, when it comes to primary structure what "the brain trust" thinks doesn't really matter.

Been there done that. Vans answer is it should be fixed. It really isn't as bad as it seems though. Only 2 doublers need to be replaced. Total job took me about 15 hours

Why are there so many sanding scratches and other marks on the part? Did they grind/file/sand on it too?

After finding something like that you should look over the entire structure very carefully.

The deeper gouges might be from trial fitting into an equally poorly finished spar pass through. The lighter sort of mangled looking lines around the hole are mill marks. These spars where made from raw bar stock. I spent days sanding and polishing out these mill marks before I primed and assembled them. Honestly, not sure if it makes that big of a difference but....

Default Hole

[IMG][/IMG] I encountered the same problem on my -4. I emailed Vans and included the photos. Their response was replace the rear carry through spar and the attach point on the wing. This is unacceptable. I believe they told me you needed 5/16" clearance around the hole. It's an easy fix. The downside is you have to redo the wing sweep and incidence.

Could the bolt hole not be enlarged to include the smaller pilot hole and use a larger bolt?
It wouldn't be easy to but would be easier than replacing the rear spar carrythrough.
