From Rich Stowell's book Stall/Spin Awareness, chapter 18
(re Cirrus and similar)
The Cirrus is not approved for spins, and has not been tested or certified for spin recovery characteristics. The only approved and demonstrated method of spin recovery is activation of the Cirrus Airframe Parachute System (CAPS). [..]
While the stall characteristics of the SR20 make accidental entry into a spin extremely unlikely, it is possible.
Paraphrasing further from that chapter 18: while standard certification requirements of single engine airplanes require spin certification and demonstrated spin recoverability from early stages of spin, these requirements were waved for the Cirrus and instead the Cirrus was certified based on the availability of the parachute system, allowing it an "Equivalent Level of Safety (ELOS") rather than fulfilling the standard certification requirements.
From the information up-thread is appears a spin was entered (by whatever cause), the parachute was not pulled (for whatever cause or reason), and the resulting traces sadly appear consistant with a continued unrecovered spin.
Quoted information is from 2007 and new insights may have been gained since, if so it would be interesting to know of. Other than that probably little more to expect until the report comes out.
