Boeing tumbled early Monday on heightened scrutiny by regulators and prosecutors over whether the approval process for the company’s 737 Max jetliner was flawed.
A person familiar with the matter on Sunday said that the U.S. Transportation Department’s Inspector General was examining the plane’s design certification before the second of two deadly crashes of the almost brand-new aircraft.
Separately, the Wall Street Journal reported that a grand jury in Washington, D.C., on March 11 issued a subpoena to at least one person involved in the development process of the Max. And a Seattle Times investigation found that U.S. regulators delegated much of the plane’s safety assessment to Boeing and that the company in turn delivered an analysis with crucial flaws.
