GEnx-1B engine receives FAA certification

The GEnx-1B engine for the Boeing 787 Dreamliner received airworthiness engine certification from the U.S. Federal Aviation Administration. The FAR (Federal Aviation Regulation) 33 certification follows an extensive two-year ground- and flight-test program that involved eight engines and two flight-test programs on GE’s 747 flying test bed. During its development and certification program, the GEnx ran 4,800 cycles and more than 3,600 hours.

With more than 1,100 engines sold to date, the GEnx is the fastest-selling engine in GE’s history. Based on the proven architecture of the GE90, the GEnx will succeed GE’s CF6 engine. Compared to the CF6, the GEnx will offer 15% improved fuel efficiency, which translates into 15% less CO2. It is designed to stay on wing 30% longer than the CF6, while using 30% fewer parts, greatly reducing maintenance.
