The Diamond is not bizjet, it’s a light piston twin with FADECs. I’d love the details on that bizjet event. The GE Passports and RR Pearl engines (Global Express 7500 and 6500, respectively) should meet FAR 33 and 25 specs. They both operate the same as other Part 25 FADECs , off a PMA after start. Those engines did the new high thrust, high altitude shutdown tests.
