I’m not qualified to critique the spin recovery in the POH but I feel like when you’ve significantly exceeded the aircraft’s stated performance as was done here then the POH pretty much goes out the window.
Perhaps there are plenty of GA aircraft that could have done what was done here and not had an accident outcome. The decision to do it in this particular type though is evidently flawed. That they had decided to do it earlier at a low altitude over a mate‘s house as well.....
