Boeing starts fourth 737 MAX assembly line in Everett

Dhaka: Boeing has opened a fourth 737 MAX final assembly line at its Everett facility in Washington, marking a fresh step in the manufacturer's plan to sharply increase output of its best-selling narrow-body jet amid robust worldwide aircraft demand.

Earlier, in June, CEO Kelly Ortberg had announced that the first airframe would move onto the new Everett line, dubbed the North Line, on July 6. He described it as a ⁠copy of the three 737 assembly lines already running at the planemaker's Renton facility.

Everett holds the title of the world's largest building by volume. It previously hosted assembly lines for the 747, 767, 777, and 787 and now has spare capacity following the end of 747 production and the shift of all 787 production to South Carolina.

The North Line's launch coincides with Boeing lifting monthly 737 output from 42 to 47 aircraft. The company, however, does not expect the extra line to push production higher until early 2027, when it hopes to reach a monthly rate of 52 jets.
