I believe that part of the certification process to allow an aircraft to be certified for intentional spinning, is that it will recover itself within a reasonable time, with no pilot input, assuming C&G and W&B limits are correct.
A 172 is certified in the Utility cat, though for someone like me, 6'1" weighing a good few Kg, I calculated I can only carry about 10 Gals of fuel :-) (or a very small passenger)
