The following is a fatal accident in the USA after a likely SAS cut following loss of SA.

I do however struggle to see how SAS CUT in good VMC could reach the point of barrel rolling the aircraft. And I have seen some very spirited attempts to mis-handle the aircraft!

Well that's exactly what it was (https://aerossurance.com/helicopters...ne-overspeeds/). That makes by my reckoning five accidents on EC135 due to inadvertent pressing of the SAS DCPL button in flight and then loss of control. (G-IWRC, G-SPAU, YR-CPC, N62UP). Interestingly with an AFCS fitted, only one emergency (AHRS failure followed by second AHRS fail) actually involves touching that switch at all. All the others are only applicable to non AFCS aircraft (although this is not highlighted in the Airbus FRC). Ironic that a switch that is only used in a very improbable emergency should be a major cause of 5.

Definitely an emergency that needs training (preferably in a sim!)
