Boeing CEO Kelly Ortberg said the 777-9 certification programme is behind schedule, increasing the risk of further delays to the long‑delayed 777X programme and customer deliveries. Test aircraft haven’t revealed new technical faults, but Ortberg warned there remains a “mountain of work” to finish certification.

Briefing
Certification slippage increases near‑term delivery uncertainty for airlines awaiting 777-9s and compounds a programme already years behind its original timeline; see earlier coverage of the 777X’s certification trajectory (near‑certification expectations).
The remaining workload includes extended ground campaigns — notably the 63‑day brake test campaign that prolonged the 777X test programme — which directly feed regulator approval timelines.
Any additional delay will squeeze OEM delivery cadence and airline fleet plans at a time of volatile monthly output; Boeing’s recent delivery swings illustrate limited buffer capacity for absorbing schedule slips.
