An interesting report.
In summary: It talks of the spin charecteristics not being fully tested as required for JAA certification WITHOUT the CAPS system being fitted.
I do note the one comment in the report:
It must be assumed that the SR20 has some unrecoverable characteristics. In the SR20 proper execution of recovery control movements is necessary to affect recovery, and aircraft may become unrecoverable with incorrect control inputs.
I also note the remedy suggested by Cirrus:
Proposed Procedure. Cirrus has reached strong conclusion that any spin recovery guidance in the AFM distracts pilot from immediately activating CAPS system when the aircraft has departed controlled flight. Cirrus is removing existing references to spin recovery in its current AFM. The clear AFM procedure will be to activate CAPS system in the event that control is lost. The new proposed procedure can be found in Appendix 4.
