I can’t see how you can blame the aircraft . The first accident was caused by the student being chock a block full of Fentanyl and the second by a relatively low time pilot putting on a crazy flying display.
There have supposedly been a number of them do the same all over the world. Would have to assume that our regulators have looked into those. It’s bordering on unprecedented action and short of the MU2 limitations, there are very few aircraft out there with handling limitations placed upon them. Jabiru of course, had engine limitations, not handling. Will be interesting to see where it leads.
