Renton, Wash. —Boeing plans to begin building new 737 Max airplanes on July 6 at a final assembly line it is opening north of Seattle, CEO Kelly Ortberg told CNBC on Friday. Ortberg said, “We’ll be loading our first airplane on July 6, so just about a month from now, we’ll be bringing that [fourth] line alive.
” The new 737 Max final assembly line in Everett, Washington, is intended to act as a catalyst for increasing Max production to 52 jets per month, a pace expected to begin next year. Boeing is currently building 47 Max jets per month after ramping output from 42 a month earlier this year. The company’s production remains capped by the Federal Aviation Administration, which imposed limits after a door plug blew out on an Alaska Airlines plane in January 2024, triggering safety and quality reviews of Boeing’s manufacturing processes.
Ortberg said Boeing’s leadership aims to reset the production track record, emphasizing a more stable workflow and slower ramp when needed, with a focus on not moving work down the line until the system is stable. The long‑term goal cited by Boeing is 63 Max jets per month, contingent on supply‑chain conditions. The line will begin with the 737 Max 10, a stretch version of the single‑aisle plane that FAA certification is expected before year‑end, paving the way for first Max 10 deliveries.
