1) The DA40 is not spin certified, or so my AFM states in chapter 2.9, operating limitations.
3) The 40 might have been the G1000 release platform, but what I've experienced first hand and subsequently read on this forum suggests the package has been little improved since Diamond's adoption.
But I too find an aircraft's propensity to fly, while hemorrhaging airspeed no less, a fine aerodynamic quality.
And I too hope Diamond Canada's new management has the vision enough to release a DA40 version 2.0.
To be particular needs be, a few were, in general the DA 40 has been spin tested, and the DA20 was spin certified (http://www.diamondaircraft.com/aircraft/da20/). "In fact, there is a model of the DA 40 that is approved for intentional spinning. That is the DA 40 F model (with carb IO-360). The approval requires a jettisonable canopy as well. As I recall it there were only a couple of these configurations that were actually sold and both of them are in China." The Cessna 172 has not been certified either.
spin certification is generally reserved for acrobatic aircraft.
Here is the OEM video of the spin testing. the demonstration for Normal category aircraft shows the spin being entered in one turn and recovery in one term, including video text overlay for emphasis:
in contrast to the Cirrus: "certification standards clearly say you need to do it in one turn. The test pilot conducted spin after spin in that condition trying to improve the technique to get the recovery down to that one turn.
Question: What happened?
CIRRUS Engineer: He made some progress. He got it down to one-and-a-half turns. Then on the 30th attempt, the spin was entered into with a greater yaw rate and it entered an unrecoverable spin. Fortunately the test pilot was wearing a parachute and he successfully bailed out. What this means is that even test pilots will find the condition that a plane will not recover from – the cliff – and sometimes it comes down to how fast the plane initially slices into the rotation with the yaw rate."

Ergo their parachute.
