U.S. investigators began an inquiry into a stall-prevention feature in Boeing Co.’s 737 Max jets just weeks after a Lion Air jet plunged into the Java Sea off the coast of Indonesia, people familiar with the matter said.
A law enforcement agent with the Transportation Department Inspector General’s office contacted at least one Federal Aviation Administration official a few weeks after the crash to ask about how the system was certified, said one of the people, who asked not to be named because the probe is confidential.
