GE Aviation (General Electric, IW500/6) has expanded its TrueChoice™ FlightHour agreement for engine maintenance, repair and overhaul with Southwest Airlines to include the CFM56-7B engines powering 83 SWA Boeing 737-700 and 737-800 aircraft. This means that GE has over 1,400 CFM56-7B engines operated by Southwest covered with MRO services.
The specific terms of the new agreement were not released.
The CFM56 series of high-bypass turbofan aircraft engines are a product of CFM International, the joint venture of GE Aviation and Snecma, in which each of the partners manufactures particular components and assembles the final articles, and services the engines of a commonly held design.
GE Aviation produces the high-pressure compressor, combustor, and high-pressure turbine, and Snecma manufactures the fan, gearbox, exhaust and the low-pressure turbine. The engines are available in four design variants. Reportedly, the CFM56 is one of the most common turbofan aircraft engines in the world.
