Boeing’s legal troubles could soar following decisions by several countries, including the United States, to ground its newest model of commercial aircraft following a March 10 crash in Ethiopia that killed 157 people.

On Wednesday, the Federal Aviation Administration issued an emergency order temporarily grounding the entire 737 Max series of aircraft in the United States. The circumstances of the Ethiopian Air flight’s crash bore resemblances to that of another 737 Max 8 aircraft owned by Lion Air that crashed Oct. 29, killing 189 people—although the cause of both crashes remains unknown.
