Williams to Power New Pilatus PC-24, as Two Other Williams Turbofans Receive FAA Certification and Begin Production May 21st, 2013

Certification and Begin Production Geneva, Switzerland, EBACE, Tuesday, May 21, 2013. Williams International is pleased to confirm that the newly announced Pilatus PC-24 is powered by twin FJ44-4A turbofan engines. These engines are rated for normal takeoff thrust of 3435 lbf at ISA+8 deg 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. The engine provides the operator a class-leading TBO of 5000 hours with an on-wing inspection of the hot section at 2500 hours.

“We are thrilled with Pilatus’s selection of Williams as the propulsion supplier for their exciting new PC-24, and proud of our proven FJ44-4 engine and its recent enhancements,” said Gregg Williams, Chairman, CEO, and President of Williams International.

Production has recently begun of two other new Williams turbofan engines – the FJ44-1AP-21 and the FJ44-4A-32 – that earned FAA certification on 17 May 2013 and 13 March 2013 respectively.

The FJ44-1AP-21 that powers Cessna’s new Citation M2 light jet produces 10-15% more altitude thrust (depending on conditions) and consumes several percent less fuel at long range cruise than the preceding FJ44-1AP, enabling the M2 to climb quickly and cruise fast and far. The engine also provides significantly higher thrust at hot and high takeoff conditions and an increase in the time between overhaul (TBO) from 3500 to 4000 hours.

The FJ44-4A-32, now entering production for the Hawker 400XPR, is a variant of the FJ44-4A engine that powers the Cessna CJ4 as well as the newly announced Pilatus PC-24. A pair of FJ44 engines rated to 3230 pounds thrust produce 470 pounds more thrust than the engines they replace, enabling the 400XP to climb to 37,000 feet 8 minutes faster than the 400XP. And the FJ44’s far superior fuel economy, together with winglets, extend the range 43% from 1,360 to 1,950 nm.

The new FJ44-1AP-21 and FJ44-4A-32 join 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, FJ44-1AP-21 and FJ44-4A-32 engines incorporate durability improvements gleaned from 8 million hours of operation of the 4400 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) that provides more value at lower cost than any competing engine maintenance program.
