The U.S. aviation regulator said on Tuesday it would not ground Boeing 737 MAX planes.
Many countries are grounding their 737 planes after a crash in Ethiopia killed 157 people.
The Federal Aviation Administration’s Dan Elwell says it is not reason enough to ground them all.
The European Union’s aviation safety regulator has suspended all flights in the bloc by the 737 MAX.
A U.S. Senator who chairs a panel overseeing aviation suggested the US take similar action.
The tragedy in Ethiopia is the second event since October involving that type of plane.
Elwell has said no foreign civil aviation authorities have provided data that would warrant action.
If any safety issues are identified, the FAA will “take immediate and appropriate action,” he said.
