The type of planes involved in two deadly crashes has been grounded in the U.S., as well as many other countries around the world.
A total of 371 planes were taken out of service Wednesday -- all Boeing 737 Max aircraft.
The decision was made after countries across world, from Canada to Europe, to Asia and the Middle East, decided to ground the planes.
According to Boeing, they support the decision out of an abundance of caution, but they still have full confidence in the planes.
Officials with the U.S. Department of Transportation say they'll be heading to Ethiopa to help with the investigation of the crash.
The FAA released a statement, saying, “The agency made this decision as a result of the data gathering process and new evidence collected and analyzed at the site. This evidence, together with newly refined satellite data available to FAA, led to this decision."
An exact cause of the crash in Ethiopa has not yet been determined.
