The Williams International FJ44-4A-QPM turbofan, which powers the new Pilatus PC-24 twinjet, has received type and production certification from both the FAA and EASA. Production deliveries of the engines to Pilatus Aircraft have begun, Williams said. PC-24 certification is expected by year-end, according to Pilatus.

 


These engines are each rated for 3,435 pounds of normal takeoff thrust at ISA+8, and more than 5 percent added thrust is available, if needed, through a new automatic thrust reserve feature, the company noted. Other new features of the FJ44-4A-QPM include an anti-ice and noise-suppressing inlet; integral pre-cooler to condition engine bleed air and reduce drag losses; and passive thrust-vectoring exhaust nozzle technology.

 


The PC-24 will also be the first FJ44 application to take advantage of Williams’s “Quiet Power Mode,” which allows the engine to provide “quiet, efficient ground power,” eliminating the need for a traditional APU. In addition, the FJ44-4A-QPM is the first FJ44 model to be certified with Williams's “latest and most advanced” Fadec that will be incorporated into all models in the FJ33/FJ44 turbofan family. Engine TBO is 5,000 hours, with an on-wing hot-section inspection at 2,500 hours.
