Another Williams Turbofan Added to the Product Line October 4th, 2011

Williams announces a new and improved version of its FJ44 engine that will power Cessna’s new Citation M2 light jet. The new FJ44-1AP-21 produces 10-15% more altitude thrust (depending on conditions) and consumes less fuel at long range cruise than the previous version, 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 new FJ44-1AP-21 joins a comprehensive product line of FJ33 and FJ44 engines that covers the thrust spectrum from 1000 to 4000 pounds thrust. All feature rugged and highly efficient component technology, health-monitoring FADEC controls, and ultra low-emissions combustor technology. All of these engines are on display at Williams International’s NBAA display (booth C8116).

While Williams engines are already recognized for their ruggedness and reliability, the FJ44-1AP-21 engine incorporates durability improvements gleaned from 7 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 large part to  the Total Assurance Program (TAP) that provides more value at lower cost than any competing engine maintenance program. The Cessna-Williams TAP Advantage engine maintenance program is available for the new M2.
