Boeing 737-10 Certified By The FAA

The Federal Aviation Administration, after more than half a decade, has approved the Boeing 737-10 and issued the necessary certification.

FAA certification means Boeing has removed the final roadblock in its long programme to bring the aircraft into scheduled passenger service after years of delays.

The FAA announced on 20 October 2026 that it had issued an amended type certificate for the 737-10 after confirming compliance with applicable design requirements and that all safety requirements had been met.

The high-capacity model of the 737 MAX family was the last remaining variant of the series, which first entered service nine years ago with the 737-8, to still receive FAA certification.

The pandemic, quality control problems, software and systems issues, and FAA certification delays made the jet an example of a new era of commercial aircraft approvals and tighter process control.

Boeing 737-10 finally cleared for delivery and passenger flights

According to the FAA, the 737-10 certification followed years of reviews and a test-flight programme covering thousands of hours. Only after those years of review could the agency determine the jet was safe to certify and enter commercial service.

The agency said the 737-10 must also incorporate safety improvements linked to the Aircraft Certification, Safety and Accountability Act and recommendations from the National Transportation Safety Board over time.

The changes include updates to the flight control systems and the angle-of-attack sensor, the central focus of the certification overhaul after two fatal accidents involving the 737-8 in 2018 and 2019 that led to global groundings and prolonged approval of the remaining variants, like the 737-10.

Largest 737 MAX to finally debut

The 737-10 is the longest variant in the 737 MAX family, positioned above all other variants, including the 737-9, with a fuselage stretch designed to accommodate up to 230 passengers in a single-class configuration and offer a denser layout option.

While final configurations will vary across the 737-10 at service entry, the single-aisle is part of a shift by passenger airlines to prioritize capacity on their single-aisles this decade and move more passengers per flight into congested hubs.

The entry into service, while vital for Boeing to clear the remaining hurdles on the MAX programme and begin scaling production and delivering jets after years of delays, is also significant for airlines that have been awaiting FAA certification.

Boeing has been selling the 737-10 for a considerable period, and delivery windows in contracts first established with airlines have ultimately not been met. Airlines that committed heavily to the jet have been forced to keep older, less efficient jets, raising fuel and maintenance costs.

The delayed 737-10 debut has also, in the worst case, pushed airlines to reconsider their orders for the type and instead look to Airbus and the certified, more readily available A321neo for future single-aisle operations.

Delays and a lack of innovation on the 737 MAX, like the A321XLR, have ultimately cost Boeing unrecoverable market share, even with certification. However, clearing the hurdle that kept the jet from debuting and securing potential future orders is pivotal to the manufacturer’s rebuild.

What happens now?

The FAA’s decision to certify the 737-10 means Boeing can begin handing the largest MAX member over to airlines once the acceptance process is complete and production and installations are finalised.

Ultimately, while deliveries will not commence overnight for the type, similar to the 737-7, which received its certification at the beginning of August, it removes the largest source of uncertainty for the planemakers and airlines that had ordered the type but couldn’t finalise an entry-into-service plan.

Several airlines, including United and WestJet, will now begin preparing to take delivery of the high-capacity variant and integrate the model into their operations as soon as possible.
