Boeing’s 737 Max jets, the key to the company’s future in commercial aviation, were grounded after two crashes killed 346 people in late 2018 and early 2019.
Investigators suspect the crashes — a Lion Air flight in October 2018 and an Ethiopian Airlines flight in March — were due to a faulty sensor reading that caused software to push the planes’ noses down.
Airlines canceled or delayed orders of the 737 Max and the Federal Aviation Administration barred the plane from flight. The company suspended production of the 737 Max at its plant in the Seattle area in January.
