And just to add some clarity around this 'spin certification' issue, Cessna 180s, 182s, 185s, 206s are not spin approved, but they meet the spin stability certification requirements. They are NOT approved for intentional spins. The C150, 152, 172 are spin approved, but only in the utility category, they are training aircraft. BTW, the Cessna Skycatcher is NOT approved for intentional spins.
So we are not talking about spin approved aircraft here in the general sense we are just talking about GA aircraft that are required to meet certain inherent spin stability requirements for ordinary GA certification. That is the ability to recover from a spin in a specified number of rotations, again NOT spin approved aircraft.
It appears the Cirrus circumvented the stability requirements by adding a supplementary CAPs which became mandatory for ordinary GA certification.
Now if I have got that wrong, someone please correct me.
