WASHINGTON/CHICAGO: Two senior Boeing Co BA.N executives who oversaw the development of the 737 MAX defended the company’s decisions on a key cockpit system later tied to two fatal crashes, according to testimony before congressional investigators seen by Reuters.
Michael Teal, then 737 MAX chief product engineer, and Keith Leverkuhn, who was vice president and general manager of the 737 MAX program, were questioned separately by investigators for the US House Transportation and Infrastructure Committee in May.
“I don’t consider the development of the airplane to be a failure,” Leverkuhn told investigators for the House panel that is to release a final report next week on its investigation into the development of the plane, grounded since March 2019 after two crashes killed 346 people.
Leverkuhn defended the decision to tie a new safety system on the MAX, called MCAS, to a single sensor that has been implicated in both fatal crashes. Boeing has since agreed to use data from two separate sensors when the plane returns to service, which could come as early as this year.
“I think based upon our understanding and our assumptions of flight crew actions, that it wasn’t a mistake,” Leverkuhn said.
Later in his testimony, Leverkuhn added, “Clearly what was in error was our assumptions regarding the human machine interaction. Because the process relied on the industry standard of pilot reaction to a particular failure. And what was clear post accidents was that assumption was incorrect.”
Congressional investigators also questioned testimony that Boeing had never conducted an internal financial analysis to determine the impact of whether the Federal Aviation Administration would require more expensive simulator training.
Teal said that if the 737 MAX design warranted simulator training, Boeing would have created it, while acknowledging that customers may have been disappointed.
“Would airlines have been pleased with that, of course they would not have,” he said, noting that Boeing had signaled all along that simulator training would not be necessary.
Last year, Boeing confirmed it had agreed to pay Southwest Airlines Co LUV.N a $1 million per MAX rebate if the training were required.
