That wasn't a spin test; they don't normally spin test multiengine airplanes. It was a side slip test, I believe in '93. Several things went wrong on that deal.
The original Canadair Challenger business jet also crashed, at Mojave during certification, aft CG flight test... I remember that well as I stopped into Mojave that morning to get gas; about an hour before it crashed.
