Speaking of complicated, I have direct knowledge of this one, and it's a lot more complicated than you realize. Just know that the manufacturer declaring it's unairworthy has nothing to do with anything, other than them not getting their way. I'll leave it at that.

As I said before, things are ALWAYS more complicated than they seem. But your assertion that the manufacturer's opinion on airworthiness is completely irrelevant is, simply, bizarre. Do you realize that the FAA could declare the glider unairworthy based on that opinion alone? This is not hypothetical - it happened to the Blanik L13. Unless you are willing to provide more information I will stick with my origin assessment.
