Boeing 737 Max Production

Boeing 737 MAX jets sit parked Monday, Dec. 16, 2019, in Renton, Wash. Boeing Co. will temporarily stop producing its grounded 737 MAX jet starting in January as it struggles to get approval from regulators to put the plane back in the air. The company says it will halt production at the plant with 12,000 employees in Renton, near Seattle. 

Boeing's new CEO says the company must improve its culture and its repair its business.

Dave Calhoun, who began his post as CEO of Boeing Monday, sent an email to all of Boeing's employees, vowing to listen to them, customers and regulators.

"I ... see opportunities to be better. Much better," he said. "That includes engaging one another and our stakeholders with greater transparency, holding ourselves accountable to the highest standards of safety and quality."

He said the company's top priority is getting approval for the 737 Max to fly again.

"We'll get it done, and we'll get it done right," he said.

Boeing's bestselling jet has been grounded since March, following two fatal crashes that killed 346 people.
