Chris:

It is a sad time for you I'm sure, and I am only going on with this because I think it is important when something fails for those involved to understand how and why.

If the center ribs had been "glued together" you would now see torn wood all over that center rib. It would look like that small clunk behind the joiner. I'm not disputing the fact that you put glue in the ribs, but for some reason, the glue did not "glue" the two ribs together. It could be that something kept them from touching each other during the gluing process. (Joiner too long?) Or perhaps you used 5 minute epoxy and it set up before you got the wings together. (That's what it looks like.)

That is a critical joint and whoever assembled your Lancair was not careful to make it a strong joint.

I'll bet in the future your wing joints will be extra strong.
