Agreed. The only commonality is the engine manufacturer and its regulator (Pratt & Whitney / FAA). Obvious lack of confidence.
The trend for countries to ban overflight on safety grounds for aircraft not on their own register started with the 737Max. It was a big step from the past, where under ICAO rules there was automatic acceptance of aircraft registered in other countries. Importation was a different story, with validation required.
FAA really needs to get things back in order.
