The accident record clearly shows that most inadvertent spins occur at such a low altitude that recovery would be unlikely even if proper spin recovery inputs are completed. Modern flight training has moved to stall recognition and recovery because if the airplane doesn't stall it can't spin. If it does stall and proper stall recovery techniques will ensure yaw is prevented and again a spin can't occur.
Bottom line for the spin to develop you have to be stupid times 3
1) The aircraft got into slow flight and you did nothing
2) The airplane stalled and you did not recover
3) With the airplane stalled not only did you not recover but you let uncontrolled yaw develop resulting in a spin entry
If you are that clueless do you really think spin training is going to save the day for you ?
