Mysterious holes in QB wings--inboard rib
I'm about to install the wings, but there are a series of holes in a diagonal pattern in the inboard rib in the aft most part--maybe 14 or so but I don't have it in front of me right now. It REALLY looks like a bracket goes there, but I have scoured the plans looking for some instructions and can't find any. I find it hard to believe that Van's would go through the trouble of putting those holes there without a reason. Did I miss something? If so, can you provide any direction?
