I wonder what exactly went on there.
1. Did he physically try to feather the RH engine?
2. If yes, did something prevent the governor from actually feathering the prop & what could plausibly have prevented this? Did the RPM overspeed condition somehow confuse the FADEC?
3. If no, perhaps the engine was generating reduced power and somehow he thought he could bring it back to life? (although this would definitely have been a straight identify-verify-feather case, given the altitude)
Also the Diamond Service Centre didn't exactly come out well in this incident, given that they declared the engine fit for service 2 days before...
