FAA's Green Light for 737 MAX 10 Marked Imminent

The Federal Aviation Administration completed a key safety review Friday, putting Boeing (BA.N) on track to receive long-awaited 737 MAX 10 certification as soon as next week - a potential turning point for an aircraft program mired in years of regulatory setbacks.

For Boeing shareholders, FAA sign-off would unlock deliveries of the last uncertified member of the MAX family, opening a revenue stream from customers such as United Airlines that ordered the high-capacity narrowbody years ago.

Key Takeaways

• FAA completed its safety review Friday; MAX 10 approval could come next week.
• A software glitch caused a three-week delay in late September 2026.
• Certification unlocks deliveries of the last unapproved MAX variant.

Market Reaction & Context

Boeing shares fell nearly 7% on Sept. 28 when the FAA first disclosed a software bug that would delay MAX 10 certification - a sharper single-session drop than the broader S&P 500 Aerospace & Defense sub-index recorded that day. 1

The stock has tracked the certification saga closely, reflecting how central the MAX family is to Boeing's recovery narrative after its years-long safety crisis. Completion of Friday's safety review, confirmed by three sources familiar with the matter, offers investors a potential catalyst reversal. 2

What Triggered the Final Delay

On Sept. 28, FAA Administrator Bryan Bedford said the agency would not certify the MAX 10 until it assessed a software bug that Boeing itself had flagged the prior month. 2 The flaw involved a vertical navigation system that could cut off automated landing guidance if pilots needed to perform a go-around - the procedure used when an initial approach must be aborted.

Bedford was careful to distinguish the issue from the MCAS flight-control system implicated in the 2018 and 2019 MAX 8 crashes.

"The pilots remain in control of the airliner, train for these scenarios," Bedford said at the time, adding that the concern centred on "the workload component."

Bedford noted that Boeing had fixed an earlier bug in the same system but "unexpectedly introduced a new bug" in the process - a description that underscored the scrutiny regulators now apply to every software change on the MAX platform.

Certification Timeline & Commercial Stakes

The MAX 10 is the largest and last variant of the narrowbody family to await FAA sign-off. Boeing had originally planned to begin MAX 10 deliveries in 2020, a schedule dismantled first by the global MAX grounding and then by a succession of software and production issues.

The FAA certified the smaller MAX 7 in August 2026, using the most updated software version - the same version now under evaluation. 2 U.S. carriers said they were not affected by the glitch in part because they retained the option to revert to earlier software on in-service MAX models.

CEO Kelly Ortberg had signalled to investors earlier in October that approval was coming "very soon," and the completion of Friday's safety review suggests the agency reached a satisfactory conclusion on the software question. 2

Outlook

Boeing said it continues "to follow the lead of the FAA as we work through the certification process," and the FAA reiterated that "safety dictates the certification timeline." 2 If approval arrives next week as sources indicated, Boeing would move quickly to begin deliveries to carriers including United Airlines, which has publicly debated how to configure its large MAX 10 order.

The milestone would mark the formal close of the MAX certification chapter - though analysts note that Boeing still faces broader production-rate and balance-sheet challenges that certification alone will not resolve.

Conclusion

Friday's completed safety review removes the principal remaining regulatory barrier between Boeing and its most commercially significant near-term catalyst. The next test will be whether the FAA issues the formal type certificate on schedule and whether Boeing can convert that approval into deliveries fast enough to matter for its 2026 financials.
