Wing Attach Fitting Welded In Wrong Spot

That is pretty typical of welded design. Adding a fillet in that areawould add no material strength and in fact could reduce the strength of thefitting by thinning the area in the bend.EAA’s welding handbook is excellent at explaining the engineering ofjoint design aimed at the homebuilder

Ah, I see what you're saying. A valid concern and I would have wondered the same thing, but the plans actually specify welding only across the top and bottom of the fitting before forming and welding the strap over it.

The plans are the correct way to weld the fitting. While welding all the way around a fitting seems like the strongest from a logical standpoint, it may end up being weaker than a couple of properly located welds.

Great progress Tony!
