Williams earns FAA and EASA certification of FJ44-4A-QPM engine August 4th, 2017

04 August 2017. The Williams International FJ44-4A-QPM engine has been awarded type certification and production certification by FAA and EASA, and production deliveries have begun. Two of these turbofan engines power the new Pilatus PC-24 Super Versatile Jet that will begin deliveries later this year. These engines are rated for normal takeoff thrust of 3435 lbf at ISA+8°C, and more than 5% added thrust is available if needed through a new Automatic Thrust Reserve feature.

These engines also boast several other new features that help to make the PC-24 quieter and more efficient. As part of an integrated propulsion module, Williams is supplying an anti-iced and noise suppressing inlet, an integral pre-cooler to condition engine bleed air and reduce drag losses, and its patented EXACT™ passive thrust vectoring exhaust nozzle technology. The PC-24 will also be the first FJ44 application to take advantage of Williams’ Quiet Power Mode™, a new proprietary feature allowing the FJ44 to provide quiet, efficient ground power, eliminating the need for a traditional APU. And the FJ44-4A-QPM is the first FJ44 model to be certified with Williams latest and most advanced health-monitoring FADEC system that will be incorporated into all models in the FJ33/FJ44 turbofan family. The engine provides the operator a class-leading TBO of 5000 hours with an on-wing inspection of the hot section at 2500 hours.

“I am grateful to the Williams team and their FAA and EASA counterparts for the cooperative work that led to this TC, and we look forward to building these engines for the exciting new Pilatus PC-24,” said Gregg Williams, Chairman, CEO, and President of Williams International.

The new FJ44-4A-QPM joins a comprehensive product line of FJ33 and FJ44 engines that cover the thrust spectrum from 1000 to 4000 pounds thrust. All feature rugged and highly efficient component technology, health-monitoring FADEC controls, and low-emissions combustor technology.

While Williams engines are already recognized for their ruggedness and reliability, the FJ44-4A-QPM engine incorporates durability improvements gleaned from 12 million hours of operation of the 5300 FJ44 engines in service. Williams International's world class product support network continues to rank first with owners and operators, due in large part to the Total Assurance Program (TAP Blue) that provides more value at lower cost than any competing engine maintenance program, and even covers Foreign Object Damage (FOD).
