Boeing will open a fourth 737 MAX production line in Everett by midsummer.

Boeing has confirmed it will open a new assembly line for the 737 MAX in Everett, Washington. This facility, known as the North Line, is scheduled to begin operations by midsummer 2026. This is a major change for the company. For decades, Boeing built all 737 jets at its Renton factory.

The expansion into Everett uses space once used for the 747 and 787 programs. By opening this fourth line, Boeing hopes to solve its delivery backlog. The company is currently working to raise its production rate from 38 to 42 jets per month.

Production Goals and Targets

Boeing executives shared these plans at a recent aerospace conference. They expect the new line to help reach a target of 47 jets per month by late 2026. In the long term, the planemaker wants to build 63 jets every month. This growth depends on a stable supply chain and workforce.

• Current Rate: 38 aircraft per month.
• Near-term Goal: 42 aircraft per month.
• 2026 Target: 47 aircraft per month.
• Future Goal: 63 aircraft per month.

Regulatory Oversight and Quality

The FAA continues to watch Boeing closely. The regulator capped production after a midair incident in early 2024. Boeing must meet strict quality and safety metrics before it can ramp up further. The company says it is "loading" its system now to test for stability.

Industry experts say the North Line will likely focus on the 737 MAX 10. This is the largest version of the MAX family. Airlines like United and Ryanair are waiting for these planes. However, the MAX 10 still needs final certification from regulators.

Impact on the Aviation Industry

This move matters to airlines and passengers worldwide. More production means faster deliveries for carriers waiting to refresh their fleets. It also signals that Boeing is confident in its recovery. The IATA has noted that global travel demand remains very high.

Suppliers are also being told to prepare for a 15% increase in parts orders. This will test the global supply chain, which has struggled with delays recently. Boeing believes starting the North Line now is the right move for future growth.
