GE9X engine

GE Aviation announced its GE9X engine, world’s largest jet engine, has been certified by the U.S. Federal Aviation Administration (FAA) authorities, a key milestone in its journey to power the new twin-engine Boeing 777X family.

The FAR (Federal Aviation Regulation) Part 33 certification involved eight test engines. This certification achievement culminates GE Aviation’s renewal of its commercial jet engine portfolio, including the GEnx for the Boeing 787 Dreamliner and the CFM LEAP engine.



The GE9X test engines completed just under 5,000 hours and 8,000 cycles for certification.

John Slattery, president and CEO of GE Aviation, said:

“It takes the world’s best talent in jet propulsion to create a game-changing product like the GE9X engine. There is no substitute that can achieve the combination of size, power and fuel efficiency of the GE9X. This engine will deliver unsurpassed value and reliability to our airline customers. I want to congratulate the entire GE9X team and thank Boeing, our partners and suppliers for the collaboration on this incredible achievement.”



Bill Fitzgerald, vice president and general manager of Commercial Engines Operation for GE Aviation, said:

“Just as the GE90 pioneered new technology for commercial aircraft engines more than 25 years ago on the Boeing 777, the GE9X sets the new standard for engine performance and efficiency thanks to the incorporation of GE’s most advanced technologies developed over the last decade.”
