The Transportation Department's inspector general is also looking into the FAA's approval of the Boeing 737 Max, a U.S. official told AP. It's also under scrutiny in the March 10 crash of an Ethiopian Airlines jet that killed 157. The grand jury issued its subpoena on March 11, one day after the Ethopian Airlines crash, according to the person who spoke to The Associated Press. Muilenburg did not refer to the reports of the Justice Department probe, but stressed his company is taking actions to ensure its 737 Max jets are safe. Ethiopian Airlines says its pilots received special training on the software.
