The PW500 turbofan engine family is the engine of choice for light to mid-size jets in the highly demanding fractional jet ownership market thanks to its outstanding reliability, durability, and operating economics. The PW500 family is comprised of 3 engine series and 7 models, ranging from 2,900 to 4,500 pounds thrust, with more than 2,500 engines produced having accumulated over 5.7 million flight hours. Success of the PW500 in the fractional ownership and general business jet markets stems from its impressive durability, with overhaul intervals that have escalated beyond 10,000 hours together with an impressive reliability track record, all complemented by comprehensive maintenance cost guarantee plans. PW500 engines continue to incorporate the latest advanced technologies to maintain their market leadership. Furthermore, the latest Full-Authority Digital Engine Control (FADEC) in many of the PW500 models provides reduced pilot workload and advanced engine health monitoring/diagnostics, assuring a high standard in aircraft dispatch availability.

Operators of PW500 engines are supported by P&WC’s industry-leading global customer support. This includes over 30 P&WC-owned and designated service facilities around the world, more than 100 field support representatives on all major continents, a 24/7 Customer First Centre for rapid expert support, the most advanced diagnostic capabilities for this market and the largest pool of P&WC rental and exchange engines in the industry.

PW500 engines incorporate the latest advanced technologies in the drive to exceed our customers’ expectations in performance, reliability, durability, fuel consumption and environmental friendliness. Seven PW500 models have been produced ranging in thrust from 2,900 to 4,500 pounds. The PW500 is a two-spool engine with a three-stage high pressure compressor driven by a single stage, cooled high pressure turbine and a two-stage low pressure turbine driving a robust, efficient fan. The PW535 and PW545 Series incorporate an added compressor boost stage driven by the fan. A high efficiency reverse-flow combustor provides low emissions and fuel consumption. An advanced exhaust mixer further contributes to the engine family’s low fuel burn and noise. Furthermore, the latest Full-Authority Digital Engine Control (FADEC) in many of the PW500 models provides reduced pilot workload and advanced engine health monitoring / diagnostics, assuring a high standard in aircraft dispatch availability.

The result is a durable, compact, light weight design that powers the majority of fractional business jet operators.
