One of those papers clearly says that the SR20 was tested, made an application for spin resistant certification, and failed to get it.
I have no idea about a spin-resistant certification, but I do know about JAA testing of the Cirrus SR20 Equivalent Level of Safety to satisfy the JAR 23.221 certification for spin recovery. See this
web page to download a copy of the report published by JAA. The ultimate conclusion of the spin testing was that the ELOS criteria was satisfied. Interestingly, both the FAA and JAA acknowledge that the majority of general aviation pilots do not receive spin training as it is no longer required for pilot certification.
So, one can pine away for more pilot skills or acknowledge that additional safety innovations help the average pilot. We need ways to attract more pilots to keep general aviation alive.
