Bloomberg News first reported on Amazon’s letter to Wyden.
Boeing updated an existing plane, the 737 NG, because designing, building and securing approval for an entirely new plane could take as long as 10 years and Boeing was pressed by a new plane from Airbus, the A320neo. But the larger, more fuel-efficient engines on the MAX forced designers to place them closer to the fuselage and farther forward on the wing. This changed the plane's handling characteristics.
Boeing is expected to disclose details of its anti-stall software upgrade on Wednesday and confirm plans to make the alert mandatory.
Boeing Co on Thursday raised its rolling forecast for China's aircraft demand for the next 20 years, making the country a bright spot in the aviation market even as COVID-19 decimates global deliveries over the next few years.
Boeing has not furloughed any workers. But some of its subcontractors — most notably Spirit AeroSystems, which builds fuselages for the MAX — earlier this month cut 2,800 jobs when production was halted. General Electric, which builds the engines for the MAX, laid off 70 temporary workers earlier this month.
