Boosting Boeing 737 Max Production with New Final Assembly Line in Everett

Boeing will begin production of 737 MAX aircraft on a new final assembly line in Everett, Washington, on July 6. The company intends for the new facility to serve as a catalyst to increase production of the MAX series to 52 jets per month.

The facility, referred to as the North Line, marks the first time the company will manufacture 737 models in Everett. This expansion of single-aisle production capacity is designed to allow Boeing to better meet market demand.

The North Line is capable of building all 737 MAX models. Initial production efforts will focus on the 737-8, 737-9, and 737-10 variants.

CEO Kelly Ortberg has toured the North Line as part of the company’s efforts to move toward higher production rates for the 737 program.

Boeing has designed the Everett production process to replicate the build process currently utilized at the Renton factory. However, the Everett site will introduce the 737 Wing Transport Tool, which is used to ferry partially completed wings for final assembly.

To staff the new line, Boeing is hiring and training hundreds of employees. The workforce is a combination of new hires and existing teammates transferred from the company’s operations in Renton, Everett, and Moses Lake.

The company is utilizing this blend of experience to maintain safety and quality standards across 737 production. This strategy ensures that new teammates receive support from experienced mechanics during the transition.

As part of the training process, experienced personnel are being deployed to the Renton facility to become familiar with the 737 program and product before the North Line becomes operational.

John V., a Boeing employee of nearly 40 years and a workplace coach for the Quality team in Everett, has transitioned to a role as a Federal Aviation Administration (FAA) and customer coordinator for the North Line. Regarding the transition, he stated, This will be my first time working on the 737 program, and added, But we are doing the training right.

Other new additions to the team include Jaden M. And Alondra P., who were hired in late 2025. Jaden M., who is responsible for installing the dorsal fin in Flow Day 1, noted that Opening a new production line is something special, and that we have to do it right.

The launch of the North Line represents the opening of a fourth 737 MAX final assembly line, expanding the company’s manufacturing footprint beyond its long-running production sites.
