Common on, if you are going to take part in the discussion you have to READ the posts before. I have set out what spin testing the JAA / EASA / FAA have done. The testing clearly was not as comprehensive as for an aircraft cleared for intentional spinning but it would seem it was no less comprehensive that many aircraft that are not approved for spinning and dont have a chute.
Irrelevant. The Cirrus wasn't tested for, demonstrated for, or certified for spins, or spin recovery. You should also do some reading, and you'll find that the post upon which you're commenting wasn't made in reply to your statement, but that of IO540. Again, contrary to his assertion that as there is no evidence the aircraft will not recover from a spin, I again offer that there is no evidence that it will.

From your post:

Test Matrix. A limited investigation of the SR20 spin behavior has been completed and results are contained in Cirrus Design reports 12419, title, and 15568, title. The incipient spin and recovery characteristics were examined during more than 60 total spin entries covering the following configurations.
What it doesn't tell you is that each incipient entry, not a spin, was done with a spin recovery chute...something the owner or renter doesn't have (but has a CAPS brs parachute system in lieu thereof). There is no evidence that the airplane will recover from a spin.

Not recently parked next to one of those, that I recall. Is it one of the old Cessna twins? ME planes don't have any spin recovery requirements.
No, it's a little bigger with more power, is more stable, and is flown by substantially higher qualified crews...with three airman watching, flying, monitoring, and a much more advanced autopilot. Never the less, contrary to your assertion that a stall won't happen anywhere else other than a base to final turn...that airplane was stalled and rolled over to the vertical with a 30,000' loss, while in cruise over the Pacific ocean. It can happen...though what that has to do with parked airplanes or airplanes not airborne, as you've introduced, is anybody's guess.

We see that several of the deployments by owners of the Cirrus have occured when they placed themselves in positions to experience upsets in flight, leading to departing controlled flight...one of the reasons that Cirrus advertises their system for use. It seems that a stall and even a spin might also be entered by a light airplane pilot in a CAPS equipped cirrus while in cruise flight...imagine that. The example is relevant after all.
