Boeing CEO Dennis A. Muilenburg has stepped down from his position "effectively immediately" following 14 months of headwinds triggered by two fatal crashes of the now grounded 737 Max line.

In a company statement, Boeing said that a “change in leadership was necessary to restore confidence in the company moving forward as it works to repair relationships with regulators, customers, and all other stakeholders.”
