Arthur,
The Cirrus Jet is designed with the Williams FJ33 engine, a very similar design to the more ubiquitous FJ44 engine that other notable light jet designs are certified with. In the roughly 1500 hours I have logged in aircraft with that engine, I have experienced two separate engine-related events in flight, in two different aircraft – a complete FADEC disruption in cruise flight and a total powerplant failure.
It will be interesting to see what can be gleaned from the engine data and the reason for the powerplant’s loss of thrust once the investigation is complete.
