In December 2013, Muilenburg became the president of Boeing.
In June 2015, Boeing announced that Muilenburg would succeed James McNerney as CEO, who was stepping down after ten years in that role. He became CEO in July 2015.
In February 2016, it was announced that Muilenburg would also succeed McNerney as Boeing's chairman. In March 2016, Muilenburg became the chairman of Boeing.
In 2018, Muilenburg agreed to a fixed-price contract to deliver two customized 747 planes to the U.S. government which left Boeing with billions in losses.
In March 2019, as a result of the Ethiopian Airlines Flight 302 crash and the Lion Air Flight 610 crash, which occurred five months prior to the Ethiopian crash, most airlines and countries began grounding the Boeing 737 MAX 8 due to safety concerns. On March 12, President Donald Trump spoke to Muilenburg and received assurances that the aircraft was safe. Trump grounded the 737 MAX family of planes on March 13.
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 would 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.
In November 2019, Muilenburg confirmed that he would not be taking a bonus for the year, after being criticized for the two plane crashes, which killed a total of 346 people.
In December 2019, Boeing announced that Muilenburg resigned as the CEO and board director, in the aftermath of the two crashes of 737 MAX aircraft. Although he forfeited stock worth $14.6m, Muilenburg was contractually entitled to receive $62.2m in stock and pension awards.
This payment by Boeing attracted criticism. Michael Stumo, who lost his daughter in the Ethiopian Airlines crash, said, 'He was fired for poor performance, and he should be treated like any other production employee who gets fired for poor performance.' Zipporah Kuria lost her father Joseph and said, 'Nobody gets their benefits when they've screwed up this much. Muilenburg and my dad are, were, the same age. Two people, and one is a privileged person who gets away with having such a big part to play in the death of so many people, and the other who trusts a product and dies for it.' US Senator Elizabeth Warren wrote regarding the payment by Boeing, '346 people died. And yet, Dennis Muilenburg pressured regulators and put profits ahead of the safety of passengers, pilots, and flight attendants. He'll walk away with an additional $62.2 million. This is corruption, plain and simple.'
He was succeeded as CEO and president by David L. Calhoun, effective January 2020. During the transition, CFO Greg Smith was interim CEO. Boeing's press release stated that, "The Board of Directors decided 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."
In January 2020, Caterpillar Inc. announced that Muilenburg had resigned from its board, and stated in a regulatory filing that his resignation was not due to any disagreement with the company.
