The U.S. aviation regulator said on Tuesday it would not ground Boeing 737 Max 8 planes after a crash in Ethiopia killed 157 people, bucking a trend of countries around the world that have suspended the aircraft's operations.

The Federal Aviation Administration's acting administrator, Dan Elwell, said a review by the body "shows no systemic performance issues and provides no basis to order grounding the aircraft."

The European Union's aviation safety regulator on Tuesday suspended all flights in the bloc by the Max 8, and a U.S. senator who chairs a panel overseeing aviation suggested the United States take similar action following Sunday's fatal crash, the second since October involving that type of plane.
