Boeing 737-10 Wins FAA Certification as Largest 737 MAX Moves Toward Airline Deliveries

The 230-seat narrowbody cleared extensive safety reviews after nearly 1,000 test flights, completing the certification lineup for Boeing’s single-aisle family.

KEY TAKEAWAYS

• The FAA certified the Boeing 737-10 on October 20, 2026, clearing the largest MAX variant to move toward customer deliveries.
• The certification effort involved nearly 1,000 flights and more than 2,000 flight-test hours alongside extensive safety and design reviews.
• The aircraft seats up to 230 passengers and has a manufacturer-stated range of 3,100 nautical miles.
• Boeing reports 1,555 orders for the 737-10 from more than 30 customers.

The largest member of the Boeing 737 MAX family has secured US regulatory approval, giving airlines a new high-capacity single-aisle option after years of development and intensive safety scrutiny. The Federal Aviation Administration (FAA) certified the 737-10 on October 20, 2026, clearing Boeing to move toward deliveries, although the precise timing of entry into airline service will depend on individual operators and any other applicable regulatory approvals.

The decision closes a major chapter in the manufacturer’s MAX certification programme. With a maximum configuration of 230 seats and a typical two-class layout of 185 to 210 seats, the aircraft is aimed at airlines seeking additional capacity on busy short- and medium-haul routes without moving to a widebody aircraft. Boeing quotes a range of up to 3,100 nautical miles (5,740 kilometres) and describes the jet as offering the lowest cost per seat among single-aisle aircraft in service—an economic claim made by the manufacturer, rather than an independently established ranking.

Certification follows an extensive flight and safety review

The programme involved nearly 1,000 test flights, more than 2,000 flight hours and about 1,000 ground-test hours, supported by design reviews, human-factors assessments and substantial technical documentation submitted to regulators. Boeing’s July flight-test update gave the more precise figures of 976 flights, over 2,060 flight hours and roughly 1,040 ground-test hours.

Boeing says the 737-10 is its first commercial aircraft certified against the full requirements of the US Aircraft Certification, Safety, and Accountability Act of 2020, which strengthened expectations for documentation, human-factors analysis and safety evaluations. The approval is particularly consequential given the broader scrutiny of the 737 MAX programme following the fatal 737 MAX 8 crashes in 2018 and 2019 and the subsequent Alaska Airlines 737-9 door-plug incident in 2024.

A central technical change is an enhanced angle-of-attack system intended to reduce pilot workload when sensor-related failures occur. Boeing says the feature will become standard across the family, including through updates to other MAX variants.

“Completing the certification program clears the path for us to deliver a Boeing airplane that will set a new standard in commercial aviation,” said Stephanie Pope, president and CEO of Boeing Commercial Airplanes. The company is positioning the model around seat economics, added capacity and commonality with other 737 MAX aircraft.

Airlines gain another capacity option

Boeing reports that more than 30 customers have ordered 1,555 examples of the 737-10, accounting for more than 30% of the programme’s current order book. Across the 737 MAX family, the manufacturer reports 7,350 orders and nearly 2,500 deliveries through September 2026. These are company-reported programme figures, not forecasts of how quickly individual airlines will receive aircraft.

The 737-10 joins the smaller 737-7, which received FAA certification in August 2026, along with the 737-8, higher-density 737-8-200 and 737-9. Boeing lists the 737-7 at 135–160 seats and up to 3,800 nautical miles, the 737-8 at 160–180 seats and up to 3,500 nautical miles, and the 737-9 at 175–195 seats and up to 3,300 nautical miles, all using typical two-class seating figures except where otherwise indicated.

For operators, the larger jet can offer more seats while retaining the cockpit, maintenance and parts commonality of the 737 MAX family. That may prove attractive on high-demand routes, although actual operating economics depend on airline layout, utilisation, route length and fuel prices. Boeing also attributes a 20% reduction in fuel use and carbon dioxide emissions to technology improvements across the MAX family; that comparison should not be read as a route-specific performance guarantee.

Chris Payne, vice president and general manager of 737 Airplane Development Programs, credited the flight-test team with validating aircraft systems through a disciplined testing campaign. The certification represents regulatory approval of the design, not a guarantee of delivery dates or a substitute for continued production oversight and airline operational preparations.

With FAA approval now in place, attention turns to production, customer handovers and the start of scheduled 737-10 passenger operations. Further manufacturer information is available at Boeing’s website and in its certification announcement.
