Williams International Receives FAA Certification For FJ44-3AP Turbofan

Engine To Power The PiperJet Altaire, Nextant 400XT

The FAA has issued a Part 33 type certificate to Williams International for its new FJ44-3AP engine, an improved version of its FJ44-3A. State-of-the-art aerodynamics and structural enhancements have led what the company says is a new benchmark in thrust-to-weight ratio and fuel economy. Thrust was increased 8% to more than 3000 pounds, while weight was reduced 3%. The market-leading performance of the FJ44-3AP engine has already won it three new applications - the Nextant 400XT, the Hawker 200, and the PiperJet Altaire.

"I want to thank the FAA for their strong support in achieving this milestone," said Gregg Williams, Chairman, President & CEO of Williams International. "I am also very proud of our team for developing significant improvements to what was already a very good engine. The outstanding performance of the FJ44-3AP engine will lead to many new and improved airplanes."

"The FJ44-3AP is also the first to receive FAA certification of a new proprietary feature we developed," Williams added, "that converts into thrust the energy typically wasted pre-cooling engine bleed air for use in aircraft anti-icing systems. This feature, which enables much better performance in icing conditions, will be offered on Williams' other commercial engines."

The FJ44-3AP joins a comprehensive product line of FJ33 and FJ44 engines that covers the thrust spectrum from 1000 to 3600 pounds thrust. All have rugged and efficient wide-sweep fans, health-monitoring FADEC controls, and low-emissions combustor technology.

While Williams engines are already recognized for their ruggedness and reliability, the FJ44-3AP engine incorporates durability improvements gleaned from over 6 million hours of operation of the 4000 FJ44 engines in service. Williams International's world class product support network continues to rank first in annual surveys of owners and operators, due in part to Williams' Total Assurance Program (TAP) that provides more value at lower cost than any competing engine maintenance program.
