“I don’t believe the advance of the plane to be a failure,” Leverkuhn informed investigators for the Area panel this is to unlock a last record subsequent week on its investigation into the advance of the aircraft, grounded since March 2019 after two crashes killed 346 folks.
Leverkuhn defended the verdict to tie a brand new protection gadget at the MAX, known as MCAS, to a unmarried sensor that has been implicated in each deadly crashes. Boeing has since agreed to make use of information from two separate sensors when the aircraft returns to provider, which might come as early as this yr.
“I believe based totally upon our working out and our assumptions of flight staff movements, that it wasn’t a mistake,” Leverkuhn mentioned.
Later in his testimony, Leverkuhn added, “Obviously what was once in error was once our assumptions in regards to the human device interplay. Since the procedure relied at the business usual of pilot response to a specific failure. And what was once transparent submit injuries was once that assumption was once fallacious.”
Congressional investigators additionally puzzled testimony that Boeing had by no means carried out an inside monetary research to resolve the affect of whether or not the Federal Aviation Management will require dearer simulator coaching.

Teal mentioned that if the 737 MAX design warranted simulator coaching, Boeing would have created it, whilst acknowledging that consumers could have been upset.
“Would airways were proud of that, in fact they do not need,” he mentioned, noting that Boeing had signalled all alongside that simulator coaching would now not be vital.
Closing yr, Boeing showed it had agreed to pay Southwest Airways Co a $1 million in step with MAX rebate if the learning have been required.
In January, Boeing reversed path and mentioned it could suggest simulator coaching for all pilots ahead of the MAX returns to provider.
Teal, now the 777X leader venture engineer, mentioned the plane-maker has since revised some pilot assumptions within the aftermath of the 737 MAX crashes. “It’s a finding out that we at the moment are placing forth at the new plane,” he mentioned.
The interviews display each executives have been unaware of a few key information about MCAS and different MAX options right through building.
Boeing mentioned Sunday the pair supervised the paintings of loads of engineers “and may now not were, excited by each design choice and essentially trusted engineering consultants to accomplish the detailed design and certification paintings related to particular person programs.”
Boeing showed Leverkuhn retired previous this yr as he had lengthy deliberate.
