With the company under intense scrutiny in investigations into two deadly plane crashes, Boeing’s board of directors has stripped CEO Dennis Muilenburg of his dual role as company chairman.

In a statement on Friday, the Chicago-based aerospace giant says it has separated the top two roles so that chief executive Muilenburg can “focus full-time on running the company as it works to return the 737 Max safely to service, ensure full support to Boeing’s customers around the world, and implement changes to sharpen Boeing’s focus on product and services safety.”

The same company news release quotes newly elected chairman David Calhoun as saying, “The board has full confidence in Dennis as CEO and believes this division of labor will enable maximum focus on running the business with the board playing an active oversight role.”

The news comes the same day a report from a panel of international safety experts criticizes Boeing for making faulty assumptions when designing the 737 Max and for failing to disclose critical information about a flight control system to pilots and regulators.
