Icarus International supports a variety of the airline industry’s most widely used engine types. Our expertise and growing service capacity for the GE CF6-80C2 and CF6-50 series, Pratt & Whitney’s JT9D-7 and PW4000 series, the International Aero Engines V2500, CFM International's Engines CFM56-3, CFM56-5 and CFM56-7 is structured around our vision to become the preferred component supplier for the operators of these engines.


The CFM56-3 Engines is manufactured by CFM International, a 50-50 joint company between GE and SNECMA. The engine is designed for Boeing 737 second-generation: 300/400/500 aircraft. It is derived from the -2, the original CFM engine.

This super-reliable turbofan is in service all over the world nearly 4,500 strong. The engine/airframe combo 737 entered revenue service in 1984 and quickly became one of the best-selling ever.

Today, CFM offers upgrade kits for the CFM56-3, which extends life and reduces maintenance on this compact lightweight workhorse.

The CF6-80C2 emerged from CF-6080A engine featuring higher thrust and more efficient slightly larger fan. This engine has thrust ratings from 52,500-lb to 63,500-lb and entered commercial service in 1985. This high-bypass turbofan engine combines a proven core with the latest technical innovations to offer the highest reliability, longest life, and lowest fuel burn in its thrust class. Technologies from a variety of research and development programs (including the GE/NASA Energy Efficient Engine program) have been incorporated into the CF6-80C2 design, such as advanced cooling techniques to improve overall efficiency, advanced clearance control, and aerodynamic modifications of blades and vanes.

CF6* technology advances, such as a low emissions combustor and advanced high pressure turbine, maximize customer value in the 21st century. The engine entered revenue service in October 1985 and has consistently demonstrated the lowest specific fuel consumption of any large commercial transport engine in its thrust class. Currently certified on 14 wide-body aircraft models and with 16 ratings, the CF6-80C2 has received FAA 180-minute Extended Range Operations (ETOPS) approval for A300, A310, 747, and 767 aircraft, offering route structuring flexibility and added economic benefits.

This engine variant was launched in 1969 to power the long range McDonnell Douglas DC-10-30, and was derived from the earlier CF6-6. Later the engine was selected to power the new Airbus A300 and Boeing 747. The CF6-50 is a high-bypass turbofan engines rated at 46,000-54,000 pound thrust.

In late 1969, the CF6-50 was selected to power the then new Airbus A300. Air France became the launch customer for the A300 by ordering six aircraft in 1971. In 1975, KLM became the first airline to order the Boeing 747 powered by the CF6-50. This led further developments to the CF6 family such as the CF6-80. The CF6-50 also powered the Boeing YC-14 USAF AMST transport prototype.

For more than 40 years, the CF6 engine family has established an impressive operational record. CF6 engines have compiled nearly 400 million flight hours since they first entered commercial revenue service in 1971. Certified to power more than 13 different aircraft types, the CF6 has accumulated over 100 million flight cycles in service.

JT9D Model History

Pratt &Whitney’s JT9D high-bypass ratio engine was first produced in 1970 to power the newer wide-body aircraft entering service with the airline industry. This engine series introduced many innovations in structural and material design technologies and made advancements in aerodynamics that improved fuel efficiency and engine reliability.

With later models having the capacity to generate up to 56,000 pounds of thrust, the JT9D series has a proven service record as the workhorse for early variants of the Boeing 747 throughout the 1970’s (3A – 7Q), and then a model was introduced (7R4D) for the Boeing 767 in 1982.

Another model (59A) was introduced in 1984 to power the Airbus A300 and A310, and a final model (20J) was produced in 1987 to power the McDonell Douglas DC-10.

Production of this model ended in 1990, the same year it reached 100 million flight hours.



The PW4000 engine series is a high-thrust model produced by Pratt & Whitney designed to power large aircraft such as the Boeing 767 and the Airbus A300/A310. Approved for 180-minute Extended Range Twin Engine Operations (ETOPS) routes, the PW4000 has completed more than 10 million intercontinental and trans-oceanic flights with 38 different airlines worldwide.

The latest advancements in service-proven technologies contribute to the superior fuel economy and reliability of the PW4000, from which it has earned a reputation for excellent performance retention, long in-service time, and low maintenance costs. Currently available with 94-inch, 100-inch, and 112-inch fans that generate from 52,000 to 98,000 pounds of thrust, Pratt & Whitney is developing improved engine-core technology for this series to meet future performance and reliability standards for the next generation of aircraft.
