That is a CRM issue more than a technical one. Who was supposed to be flying the helicopter?
It descended at over 500 fpm for 6 minutes and would have presumably continued to do so until alerted by ATC. They may have had CAS messages but that is no excuse for not scanning the instruments at least every minute or so.
If you are SPIFR then that is all the more reason to be vigilant.Automation and 4 axis autopilots are a great aid to flying but have to be monitored.
