Use this oneGE Aviation announced that its GE9X engine has been certified by the US Federal Aviation Administration (FAA) authorities. 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.

“It takes the world’s best talent in jet propulsion to create a game-changing product like the GE9X engine,” said John Slattery, president and CEO of GE Aviation. “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.”

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

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

The GE9X engine is designed to achieve 10 percent lower specific fuel consumption (SFC) compared to the GE90-115B and five percent better SFC than any other engine in its class. The engine will also operate with less smog-causing emissions than any other engine in its class.

GE’s focus remains working with Boeing to complete the 777X flight test programme and entry into service. Eight GE9X test engines and two test spares have been produced and delivered to Seattle for Boeing’s four 777X test airplanes. Several GE9X production engines have been assembled, and GE Aviation is in the process of completing factory acceptance tests. GE Aviation is currently conducting 3,000 cycles of additional ground testing on the GE9X engine to support Extended Operations (ETOPS) approval. The GE9X team is also conducting maturation testing to help GE engineers prepare to support the engine in service. GE has received orders and commitments for more than 600 GE9X engines.
