With piston engines, single-engine planes are safer than light twins. With twice the engines, you are twice as likely to have an engine failure, and when you do, the plane is less controllable. My old flight instructor used to say that having a light twin merely allowed you to crash somewhat closer to the airport than in a single-enine aircraft.
I don't know whether that statistic will carry over to a single engine vs. twin engine light jet. Turbine engines are incredibly reliable, so it's probably a moot point. Weather and pilot error will bring down many more of these little jets than engine failures.

Which is the company that makes parachutes for airplanes. Can one be rigged to this plane?
