A former chief technical pilot for Boeing has been charged with deceiving federal regulators who were evaluating the company's 737 Max plane.
The US Justice Department said 49-year-old Mark Forkner was indicted by a grand jury in Texas of hindering the ability to protect airline passengers and leaving pilots in the lurch.
Two fatal crashes of the 737 Max in 2018 and 2019 killed 346 people.
A lawyer for the victims' relatives said Mr. Forkner had not acted alone.
Prosecutors accused Mr. Forkner of scheming to defraud Boeing's US?based airline customers to obtain tens of millions of dollars for the company.
