Washington, Jul 10 (V7N): Marking a crucial milestone in its industrial recovery, Boeing officially held a ribbon-cutting ceremony on Friday to commemorate the opening of its new "North Line" 737 MAX final assembly line inside the sprawling Everett factory.

The new production line represents the first time in history that Boeing’s bestselling narrowbody aircraft is being assembled outside its traditional production hub in Renton, 35 miles to the south. Commercial Airplanes Chief Stephanie Pope, alongside local government leaders and aerospace executives, gathered in the massive hangar—the largest building in the world by volume—to signal the beginning of a heavily regulated, gradual production ramp-up.

The space inside the massive Everett complex became available after Boeing officially ended production of the iconic 747 jumbo jet and consolidated its 787 Dreamliner assembly entirely in South Carolina. The new line is built as an exact replica of the Renton assembly lines, operating on a 10 "flow day" cycle where fuselages are progressively outfitted with wings, landing gear, engines, and interior cabins.

Despite the grand opening, production at Everett will follow a deliberate, slow-motion trajectory to avoid repeating past quality-control disasters.

Initial Cadence: Factory floors remain mostly quiet, with a newly formed crew of 1,000 workers—half transferred from Renton and half raw recruits—commencing work on the very first 737 MAX 10 fuselage.

The Growth Target: Combined with Renton, the addition of the North Line is intended to help Boeing steadily lift overall MAX production from its current cap of 47 aircraft per month up to 52 by early 2027, before eventually targeting a rate of 63 or higher.

No Firm Deadlines: "It’s a rolling start," emphasized Jennifer Boland-Masterson, Senior Director for North Line production, who explicitly declined to provide a target date for when the first completed Everett jet will roll off the line.

Overcoming Crisis and Regulatory Hurdles

The expansion is unfolding under intense, performance-based oversight from the Federal Aviation Administration (FAA). Boeing’s long multi-year crisis began with two catastrophic MAX crashes in 2018 and 2019 that claimed 346 lives. Just as a recovery seemed within reach, the program was thrown back into turmoil in January 2024 when a mid-cabin door plug blew out of an Alaska Airlines MAX 9 midflight, triggering a fresh wave of leadership changes and production freezes.

Phase / Era Monthly MAX Target Primary Milestone / Constraint
Post-Door Plug Crisis (2024) 38 aircraft Strict numerical production cap imposed by the FAA.
Ortberg Reset (Spring 2026) 42 → 47 aircraft Cap lifted for approved Quality Management System updates.
Everett Integration (Target 2027) 52 aircraft Activation of North Line to unlock the 6,100+ jet backlog.

Since taking the helm, CEO Kelly Ortberg has implemented rigorous internal quality audits, reacquired major fuselage supplier Spirit AeroSystems, and worked closely with regulators to steadily advance past the initial 38-jet cap.

However, major roadblocks remain before any Everett-built planes can hit commercial runways. The FAA must formally sign off on the specific production infrastructure plans for the North Line. Simultaneously, Boeing is locked in the final stages of a meticulous, high-stakes safety review to secure the type certification for the stretched MAX 10 variant—the exact model currently sitting on the new Everett line.
