The CFM56 is the world's best-selling commercial aircraft engine, and the most reliable of its generation, with dispatch reliability approaching 100%.
Covering the thrust range from 18,500 to 34,00 pounds, CFM56 engines have been an exceptional commercial success, powering many different models of both Airbus and Boeing jetliners.
18,500 to 27,300 pounds thrust: sole engine offered for the Boeing 737-600, 737-700, 737-800, 7378-900, 737-900ER and 737 BBJ commercial applications: C-40, P-8A, and AEW&C military applications
22,000 to 33,000 pounds thrust: sole engine offered for the Airbus A318, A318 Elite, A319, A319 CH, A320, and A321
The CFM56-5C, the most powerful engine in the family and the quietest engine in its thrust class. Purpose-designed for the Airbus A340-200 and A340-300 four-engine long-rang jetliners, the CFM56-5C is an economical engine developing 31,200 to 34,000 pounds of thrust (139 to 151 kN).
Specifically designed to power the Airbus A320 short/medium-range twin-engine jet at the outset, it later added the shortened A319 version of this aircraft. Developing 22,000 to 26,500 pounds of takeoff thrust (98 to 118 kN), the CFM56-5A is a proven, cost-effective advanced technology engine, derived from the CFM56-2 and CFM56-3 engines.
The CFM56-3 played a major role in the success of the CFM56 family on 100 to 200-seat single-aisle commercial jets. As the first advanced derivative of the CFM56 family, the CFM56-3 engine is perfectly tailored for the needs of the short/medium-haul Boeing 737-300, -400 and -500 aircraft (737 Classic family).
