At Boeing’s annual meeting for shareholders, one investor challenged chief executive Dennis Muilenburg to explain why the company built the 737 Max with a single sensor that was vulnerable to failure.
‘‘That should have gone through some sort of internal review or something,’’ the Boeing shareholder said at the meeting. His name could not be confirmed.
‘‘We don’t have to have 300-plus people die every time to find out that something isn’t reliable,’’ he said.
Boeing’s top executive and board of directors confronted difficult questions from investors and the media on Monday, the first time since two crashes of the 737 Max jet threw the company into chaos. Speaking to a half-empty auditorium in Chicago’s’ Field Museum, Muilenburg tried to reassure investors that the company takes safety concerns seriously and is working with regulators to update the technical features of the plane that contributed to both accidents.
‘‘When it comes to safety, there are no competing priorities,’’ Muilenburg said at the meeting.
In defending Boeing, the CEO stuck to a script that the company ‘‘owns’’ some responsibility for improving the safety of the 737 Max. But, to the frustration of some shareholders in attendance, he stopped short of accepting that the plane was built with any flaw in its design. He repeatedly said the crashes were caused by a ‘‘chain of events,’’ of which Boeing’s software and its sensors were only one part.
That explanation is being challenged by family members of the victims in the two crashes, some of whom stood in the rain outside the museum, holding umbrellas and placards with photos of people who died.
‘‘Their response has been a farce,’’ said Tarek Milleron, the uncle of a 24-year-old American woman who died in the Ethiopian Airlines crash in March. ‘‘It’s a hollow denial. They talk about chains of events in accidents, but we need to know the chain of events inside Boeing that led to these crashes.’’
Milleron said he traveled to the meeting from his home in Berkeley, Calif., to stand outside and draw attention to the lives of the 346 people lost in the crashes.
Muilenburg didn’t say how soon the 737 Max could fly again. He said the company is working on a software update for the safety problem and is coordinating with the FAA to prepare for a formal certification flight. Boeing hopes that will pave the way for a worldwide grounding of the Max jets to be lifted by global regulators.
Boeing’s managers and board of directors have faced growing pressure in the weeks since the second crash. Glass Lewis, an investor advisory group, said in a note to clients last month that the 737 Max crashes ‘‘indicate a potential lapse in the board’s oversight of risk management’’ and recommended that one director, former American Airlines CEO Lawrence Kellner, be voted off the board for his role overseeing the audit committee.
At the meeting, shareholders voted to keep Kellner and all other current directors who were up for reelection. Nikki Haley, the former ambassador to the United Nations and South Carolina governor, was officially added to the board after being nominated by the company in February.
Boeing paid each of its directors more than $300,000 in cash and stock last year. The group includes the CEOs of Duke Energy and biotech firm Amgen, as well as retired Navy Admiral Edmund P. Giambastiani and Caroline Kennedy, the former US ambassador to Japan and daughter of John F. Kennedy.
The board approved a 2018 pay package for Muilenburg of about $23.4 million in cash and stock.
The independence of these directors has come under question. Muilenburg holds the dual role of CEO and chairman of the board, an increasingly rare position of power for a leader of a large public company that governance experts say can undermine the board’s ability to hold him in check. Muilenburg and two other directors also serve on the board of Caterpillar, an arrangement that could limit the criticism those directors give Muilenburg at Boeing.
At the meeting, Boeing shareholders rejected a proposal to create a separate independent chairman position. Investors also voted against measures that would force the company to reveal more details about its government lobbying.
One investor who spoke at the meeting, whose name could not be confirmed, expressed concern that Boeing’s design process does not have enough outside oversight.
‘‘What are you doing to ensure that there is an outside external person or people looking in who have no interest in the outcome?’’ asked the woman, who described herself as someone who frequently travels on planes with her friends and family.
Muilenburg said the company relies on several independent checks in its process for building planes. He defended Boeing’s relationship with the FAA, which has recently faced criticism that it cedes too much of the plane certification process to Boeing.
‘‘That is a way for the FAA to leverage the deep technical expertise of our team while maintaining the independent review that’s required,’’ he said.
After the hour-long shareholder meeting, Muilenburg fielded questions from the media for about 16 minutes before walking out of the room.
