Transportation Secretary Elaine Chao requested that the department's inspector general investigate the certification process the department followed that allowed the Boeing 737 MAX aircraft into the skies. Two Boeing 737 MAXs have crashed since October, leading to a worldwide grounding of the popular jetliner.

Why it matters: The investigation adds to the probes that Boeing is facing over the crash of a Lion Air 737 MAX 8 in October, and the loss of an Ethiopian Airlines 737 MAX 8 on March 10. In the wake of the latter crash, the FAA, which is housed within the Transportation Department, ordered all 737 MAX aircraft grounded, after nearly every affected major country in the world had already done the same.
