The attachment of the vertical stabilizer on the 7 is different (different horizontal stabilizer and spar)

Thanks Stephen I will remove that post, or state disregard, because I was mistaken.

Since it's a simple part and the elongated holes are for intial assembly only.

I would make my own replacement part from the same thickness material and just have plain round holes for the bolts.

Is there a possiblity that the bolts were not fully torqued?

Default slots?

Slots are not preferred at loads points for this very reason. A better design would be line drilled. OK, now the decision for me, make a replacement part or just add a washer? Vans may consider a Service Bulletin for this finding. Did someone copy Vans?

That may have been in the older kit (RV7) mine which was built in 2009, the attach point was not pre-drailled and was to be drilled by builder.

If you make a new part it would be easy to incorporate a rather obvious load path improvement...straighten the left edge:



Is the left edge in the photo rounded and smoothed, or square-edged with an "as delivered" finish?

The most likely cause of overload is ground handling. Folks tend to use the leading edge of the VS as a handle.
