The V2500 and CFM56 are similar competing families of narrowbody commercial engines, with thrust depending on the specific engine model.

The CFM International CFM56, which was also designated as the F108 when operating on U.S. military variants, is an extensively used high-bypass turbofan engine originally designed by CFM ...

One notable example is the CFM56 family of engines, which is the most popular turbofan in aviation history. So, who makes this engine, and why is it present on so many planes?

The Federal Aviation Administration on Wednesday ordered inspections of the type of engine that exploded Tuesday on Southwest Airlines flight 1380.

CFM56-5Bs power Airbus A320-family aircraft and CFM56-7Bs power Boeing 737NGs. The order applies to 210 engines on US aircraft, the FAA says.

The over 30,000 CFM56 engines are under the wings of on thousands of airliners, but it's unclear exactly how many fake parts were installed.

The CFM LEAP engine family delivers 15 to 20 percent lower fuel consumption and CO 2 emissions, as well as a significant improvement in noise, compared to previous generation engines.

It's unclear how many fake parts may have been installed or how many aircraft might be affected. The CFM56, the world's best-selling jet engine, is on thousands of planes.

However, CFM's CFM56 powers the legacy Airbus A320 family and Boeing 737 airplane. GE's narrowbody aftermarket services revenue will migrate, over time, from the CFM56 engine to the LEAP.
