Boeing 737 MAX 10 Wins FAA Certification, Clearing the Largest MAX for Delivery

The wait is over. On Tuesday the FAA certified the Boeing 737 MAX 10, the largest member of the MAX family and the last variant still waiting for permission to carry passengers.

The Federal Aviation Administration issued certification for Boeing's 737 MAX-10 on Tuesday, Oct. 20, at a ceremony in Everett, Washington, after years of extensive review. The FAA issued an amended type certificate, confirming the aircraft complies with all applicable design and safety requirements, and an updated Production Limitation Record, which authorizes aircraft production. With production approved, Boeing said deliveries will begin in the coming months, and the aircraft can be delivered to domestic and foreign carriers.

Transportation Secretary Sean Duffy framed the grant as both a safety decision and an industrial one. After extensive safety reviews including thousands of hours of test flights, Duffy said the FAA team was ready to approve the aircraft for sale, calling it a major win for American manufacturing. FAA Administrator Bryan Bedford said the decision followed a thorough review of the aircraft's design and safety requirements, and added that the agency will continue to hold Boeing to the highest safety standards as production of the MAX-10 begins.

The safety changes the FAA required before it would sign

This was not a routine sign-off on a stretched version of an existing jet. Before granting approval, the FAA required the MAX-10 to incorporate improvements addressing the Aircraft Certification, Safety, and Accountability Act and National Transportation Safety Board recommendations, including updates to the flight-control system with an enhanced angle-of-attack sensor. Boeing said the 737-10 is the first commercial airplane certified to the full extent of that 2020 law, which mandated enhanced documentation of safety assessments and human-factors evaluations.

The enhanced angle-of-attack system matters because faulty readings from that sensor were central to the sequence of events in both fatal MAX accidents in 2018 and 2019. The new system uses monitoring software to identify sensor behaviour that does not match expected conditions and can prevent erroneous data from reaching other systems, while pilots receive an alert identifying the affected sensor and gain a switch to silence an erroneous stick-shaker warning. Boeing said the enhanced system will become standard across the MAX family, and Flightradar24 reported it will also be available as a retrofit for aircraft already in service. Testing also covered an updated engine anti-ice system, which will likewise extend across the fleet through production and retrofits.

A test programme measured in thousands of hours

The certification programme behind the grant was unusually long for a derivative jet. Boeing said the campaign included nearly 1,000 total test flights, more than 2,000 flight hours and 1,000 ground test hours, backed by tens of thousands of pages of documentation. Flightradar24, tallying the programme through its final planned certification flight in July, counted 976 flights, more than 2,060 flight hours and about 1,040 ground test hours across three aircraft. The jet itself first flew more than five years ago and had originally been due in service in 2020, so the grant closes a delay that left the largest MAX in limbo while its smaller siblings were already flying passengers.

That history includes a sharper setback only last month in TickerGrove's own coverage, when certification slipped again over a software issue. Tuesday's grant is the distinct event that resolves that thread: the approval has now been issued, not merely approached, and the remaining question is delivery execution rather than regulatory permission.

What airlines are actually getting

The 737-10 typically accommodates 185 to 210 passengers in a two-class configuration, up to a maximum of 230, with range of up to 3,100 nautical miles. Boeing claims the lowest per-seat costs of any single-aisle airplane in service and 365 nautical miles more range than competitors without auxiliary fuel tanks — both company claims, presented as Boeing's case rather than an independent finding — and points to a 20% reduction in fuel use and carbon dioxide emissions from its technology. Stephanie Pope, president and chief executive of Boeing Commercial Airplanes, said completing certification clears the path to deliver an airplane offering greater capacity, longer range and the best seat economics in its class. Chris Payne, who runs the 737 development programmes, credited a disciplined, methodical flight-test campaign.

The commercial stake is large. More than 30 customers have ordered 1,555 of the 737-10, which Boeing said is more than 30% of the MAX programme's current order book. Across the family, customers have placed 7,350 orders, with nearly 2,500 delivered through the end of September 2026. Canadian carrier WestJet is currently scheduled to be the launch customer, and United, Delta, American, Ryanair and Alaska also hold orders. Flightradar24 reported airline expectations of aircraft entering fleets beginning in early 2027, which sits alongside Boeing's own vaguer promise of deliveries in the coming months.

Why the A321neo still looms over the celebration

Certification removes Boeing's biggest excuse in the large single-aisle contest, but it does not rewind the years airlines spent planning around the delay. Flightradar24 noted that United, among others, turned to the Airbus A321neo for transcontinental needs during the long wait, and the 737-10 now enters service against an established competitor rather than an empty field. The MAX-10 gives Boeing a larger offering in a market where carriers have increasingly sought more capacity from single-aisle jets, yet every delivery slot from here is a contest Boeing must win on execution — production pace, reliability and airline confidence — not on paper specifications alone.

What to watch, and what is still unknown

The next tests arrive quickly. Boeing reports third-quarter earnings on Oct. 27, where investors will press for a firm first-delivery timetable and a production ramp plan now that both the 737-7 — certified earlier this year, in August — and the 737-10 have cleared the FAA. What remains unknown is precise: Boeing has not named an exact first-delivery date, per-airline delivery schedules have not been published, and the pace at which completed aircraft and new production move to carriers is still to be demonstrated. The certification itself, though, is no longer a forecast. It is a granted amended type certificate, a production record updated to match, and a family finally complete on paper — with deliveries now the only proof left to supply.
