Boeing Max 737 jet crisis: we should've been more open, says CEO

The head of Boeing has admitted the company made communications errors in its dealings with regulators and airlines in the wake of the 737 Max jet crisis that grounded the entire fleet.

Speaking on the eve of the Paris air show, the Boeing chief executive, Dennis Muilenburg, said the company’s communications were “not consistent” and that was “unacceptable”. Muilenburg added that the US aerospace group had failed to communicate “crisply” with regulators and carriers about the plane.

The 737 Max was grounded globally in the aftermath of an Ethiopian Airlines crash outside Addis Ababa in March that killed all 157 people on board. It was the 737 Max’s second disaster in five months, after 189 people were killed on a Lion Air flight in Indonesia in October.

Asked how the design and constructions of the 737 Max failed to capture apparent flaws in the software and sensors behind the airplane, Muilenburg said: “Clearly, we can make improvements, and we understand that and we will make those improvements.”

Investigations into the Ethiopia and Indonesia accidents have centred on the Manoeuvring Characteristics Augmentation System (MCAS), which was designed to keep the aircraft stable in flight. An investigation into the Ethiopia crash has reportedly found that the MCAS software – which automatically pushes the aircraft’s nose down to guard against a loss of lift – was activated by erroneous “angle of attack” data from a single sensor, forcing the pilots into a doomed struggle to control the aircraft.

Muilenburg added: “When I make comments about the previous design and how we followed those processes, that’s something we put a lot of thought and depth of analysis into. That doesn’t mean that it can’t be improved.”

The Boeing boss, who has been under fire over the 737 MAX design and Boeing’s handling of the crisis, said he expected the plane to return to service this year.

Muilenburg said he was “disappointed” the company wasn’t more forthcoming with information when engineers in 2017 learned that cockpit alerts intended to warn pilots about certain sensor malfunctions didn’t work or weren’t operating as intended due to a software error. The company previously said senior Boeing leaders didn’t learn about the issue until after the second crash.
