I just stumbled across this thread, but randomly happened to be looking at the NTSB website at the same time (was watching Air Crash Investigation) and decided to look up fatal crashes in the Cirrus SR20.
What I found was quite interesting was that there is not a single fatal crash (other than a test flight in 1999) that the NTSB did not determine was caused by pilot error.
In short, 1 out of the 19 recorded fatal accidents was not simply pilot error and that was a test flight, so arguably should not be taken into account in the same way.
