GE Aviation announced today its GE9X 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 nine test engines.
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 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.
