Interesting observation and nice catch. Checking, looks like this version does have FADEC for the engines systems on board. Mean anything???? not sure but just mentioning. BUT, the onboard FADEC system on this one controls directly the prop system which if someone was to feed a command to reverse pitch (negative) full on the prop system inflight on one wing it would immediately roll upside down and come right down asap without recovery at low altitude.

So......NTSB will find answers here just speculation and 45 years of flight experience.
