Genghis, I created a thread in the Tech Log forum some months back, regarding the spin characteristics of the Cirrus SR20 and SR22. Basically, these aircraft are certified to a new FAA philosophy regarding spins, in that spin avoidance is emphasized at low altitude, rather than traditional spin recovery at higher altitudes. So these aircraft (along with other recently certified GA aircraft) are NOT certified to the same spin recovery standard that your father's airplane was. These new aircraft are not even tested for spin recovery (actually due to their design, they CANNOT be spin tested, as they have no designed in ability to recover).
Here's the link to the thread, and I hope the informative links within still work.
Cirrus SR20/22 - Was this a bad idea?
