Turbofan engine engines sit at the cutting edge of technology and can last for up to 10,000 engine flight cycles (EFC). Only a select group of countries can design and manufacture jet engines (the US, UK, France, Russia, and China). Still, even fewer are making jet engines for Airbus and Boeing commercial airliners. All Airbus and Boeing commercial aircraft are fitted with General Electric, Pratt & Whitney, or Rolls-Royce engines.
