FAA OKs Williams FJ33-5A Turbofan
Since the new FJ33 engine has been selected to power the Cirrus SF50 Vision and Flaris LAR1, it also includes sensor suite redundancy.

Williams International received FAA Part 33 type approval yesterday for its new FJ33-5A engine. The turbofan employs aerodynamic and structural enhancements similar to those developed for the previously certified FJ44-3AP and -4A engines, giving the FJ33-5A more than 2,000 pounds of thrust, high fuel economy and a thrust-to-weight ratio greater than 6:1.
