Boeing is planning to suspend production of its beleaguered 737 Max planes next month, the company said Monday, a drastic step after the Federal Aviation Administration said its review of the planes would continue into next year, dashing the manufacturer's forecast.

Boeing's decision to temporarily shut down production, made after months of a cash-draining global grounding of its best-selling aircraft, worsens one of the most severe crises in the history of the century-old manufacturer. It is ramping up pressure on CEO Dennis Muilenburg, whom the board stripped of his chairmanship in October as the crisis wore on.

The measure is set to ripple through the aerospace giant's supply chain and broader economy. It also presents further problems for airlines, which have lost hundreds of millions of dollars and canceled thousands of flights without the fuel-efficient planes in their fleets.

Boeing said it does not plan to lay off or furlough workers at the Renton, Washington, factory where the 737 Max is produced during the production pause. Some of the 12,000 workers there will be temporarily reassigned.

"Today's Boeing announcement is a body blow to its workers and the region's economy," said Rep. Rick Larsen, a Democrat from Washington, where Boeing makes the Max. "The only saving grace is the Boeing leadership has promised not to lay off any workers. I am ready to work with Boeing workers to ensure they are protected and that they will have access to the necessary resources in the event of a prolonged shutdown."

"In the meantime, the FAA should continue to emphasize that safety is the guiding principle for any return to service decision for the 737 MAX. The MAX is a great airplane and will be in use for many years, but the best decision for the long-term and for the workers at Boeing is ensuring the necessary changes needed to put the plane back in service are done only with safety in mind."
