In October 2019, Boeing announced that the board had voted to separate the roles of chairman and CEO, both of which were held by Muilenburg. David L. Calhoun was elected to take over as non-executive chairman, while Muilenburg continued as CEO and president. The company said this change would enable Muilenburg to focus full-time on running the company, while it worked to return the Boeing 737 MAX to service.[14][15]
