Made a few inquiries on BOE05...
ZA005 is in San Bernardino conducting testing to demonstrate the performance of engine improvements provided by General Electric.
GE’s second package of upgrades for the 787’s GEnx-1B engine was certificated by the FAA on April 12. That’s engine-only certification.
This week’s San Bernardino flight tests are working toward the certification of the upgraded engine and plane together.
