Boeing to Build New 737 MAX 10 at Largest Factory in the World

SEATTLE- American Aerospace Giant Boeing will revive operations at its iconic Everett factory by building the 737 MAX 10, the largest model in its 737 narrow-body series.

The production shift from Renton (RNT) to Everett (PAE) aims to ease capacity strain and position Boeing for future growth in single-aisle aircraft manufacturing, according to the Seattle Times.

Boeing 737 MAX 10 Production

Boeing is preparing to establish a fourth 737 production line in Everett, Washington, dedicating it exclusively to the 737 MAX 10.

This aircraft, the longest and most technically complex in the 737 MAX series, features unique design changes, including a modified, extendable landing gear to prevent tail strikes during ground operations.

The Everett facility, once home to the 747 and 787 Dreamliner programs, will now gain a renewed mission. This decision comes after Boeing moved 787 production to Charleston (CHS) and concluded the 747 line.

By assigning the 737 MAX 10 to Everett, Boeing can continue high-volume assembly of the more common 737 variants at its Renton plant.

The new assembly line is expected to be located east of the massive Everett structure, near where Boeing currently assembles the 767 freighter and KC-46 military tanker.

Before production at Everett can begin, Boeing must address its current output limitations in Renton, which is capped at 38 aircraft per month by the Federal Aviation Administration (FAA).

The company is working to demonstrate to regulators that its processes are safe and compliant, especially following a high-profile incident involving an Alaska Airlines (AS) 737 MAX 9.

Once Boeing satisfies FAA requirements, it plans to gradually ramp up Renton’s production rates to 42 jets per month, then 47. This expansion, although not bound to a public deadline, is anticipated to reach full pace by 2026.

Certification Status of MAX 10 and MAX 7

A critical hurdle remains: certification of the 737 MAX 10 and its sibling model, the 737 MAX 7. Boeing expects FAA approval for both aircraft by the end of this year. Without certification, neither variant can be delivered to customers or produced at scale.

The MAX 10 program has faced delays due to regulatory scrutiny and design modifications. By moving its assembly to Everett, Boeing aims to streamline production while meeting future airline demand for longer, more efficient narrow-body jets.

This strategic shift also maximizes the use of Everett’s expansive infrastructure, formerly the largest aircraft assembly site in the world.

The facility, once producing 747 jumbo jets, will now support Boeing’s evolving single-aisle strategy, targeting flexibility and throughput.

Locating the 737 MAX 10 line next to the 777 and 767/KC-46 lines enables Boeing to optimize logistics, workforce deployment, and part flow across programs. This move supports long-term production goals while keeping Everett operationally relevant.
