Boeing MAX 10 Certification Nears, 777X 2027 Target Holds

737 MAX 10 Certification Nears

Boeing CEO Kelly Ortberg stated this week that the 737 MAX 10 is on the verge of receiving certification from the US Federal Aviation Administration (FAA). Speaking at Morgan Stanley's Laguna Conference on Wednesday, 17 September 2026, Ortberg indicated that only three deliverables remained for the FAA review as of Thursday, 18 September 2026.

He confirmed that all flight testing for the largest 737 MAX variant is complete, with the remaining work primarily focused on the extensive documentation phase required by the regulator. Ortberg also noted that the European Union Aviation Safety Agency (EASA) conducted a flight assessment of the MAX 10 during the previous week and provided positive feedback on the aircraft. Boeing has already commenced manufacturing the initial production models of the MAX 10 at its facilities in Washington.

Backlog and Past Delays

The 737 MAX 10 variant represents approximately 30 per cent of Boeing's current order backlog, highlighting its importance to the manufacturer's future deliveries.

The target certification date for the MAX 10 has been postponed several times over the past six years, primarily due to persistent supply chain challenges, the broader repercussions of the 2018–19 MAX grounding crisis, and technical issues related to the model's anti-ice system.

Despite these setbacks, Ortberg observed a notable acceleration in the certification process over the last two years, suggesting that the programme is now in its final stages. The completion of flight tests marks a significant milestone in this progression.

777X Progress and ETOPS Challenge

Ortberg also provided an update on the 777X programme, another of Boeing's delayed widebody jets, confirming that flight testing for the type is continuing. However, the aircraft has not yet secured its Extended-range Twin-engine Operations Performance Standards (ETOPS) certification, which is crucial for long-haul operations over water or remote areas.

The delay stems from a mid-seal issue identified within the aircraft's GE engines. Ortberg explained that General Electric (GE) is actively working on a resolution but requires additional testing beyond what was initially planned to complete the certification plan for the engine component. This additional testing may extend into next year, 2027, potentially pushing back the full ETOPS authorisation.

Implications for Asian Operators

Despite the ongoing ETOPS certification challenges and the possibility of further testing into 2027, Boeing maintains its expectation to commence deliveries of the 777X in 2027. Ortberg addressed media reports suggesting that some buyers have concerns about the 777X's technology potentially being outdated.

He clarified that there has been no change to the initial number of ordered units and that any such concerns are being managed through direct contract discussions with individual clients.

For Asian carriers, the imminent certification of the 737 MAX 10 is significant, as many airlines in the region have substantial orders for this variant, crucial for expanding their short-to-medium haul networks.

Similarly, the continued progress of the 777X offers clarity for long-haul operators like Singapore Airlines and Cathay Pacific, who rely on its range and capacity for intercontinental routes. The firm 2027 delivery target, despite engine issues, allows these airlines to finalise their operational planning for the coming years.
