Ethiopian Airlines said it's  grounded its fleet  of Boeing 737 MAX 8 jets until further notice.

The Monday announcement came one day after a crash killed 157 people on board one of its flights of the same model.

Similarly,  Chinese regulators ordered  all of the country's airlines to temporarily suspend all Boeing 737 MAX 8 aircraft operations.

The Wall Street Journal reports China's decision was made before a Boeing team even made it to the crash site.

But China said it had "zero tolerance for safety hazards," pointing out  the Ethiopian Airlines crash  was the second in recent history to involve that Boeing model going down just minutes after takeoff.

Back in October, a Lion Air plane  crashed into the Java Sea , killing all 189 people on board.

In both instances, the Boeing planes were new.

Investigators  said faulty sensors  aboard the Boeing airliner contributed to the fatal Lion Air crash.

Those sensors are meant to help correct a plane's angle compared with oncoming air or wind.  But the FAA said  a malfunctioning sensor could lead to "significant altitude loss, and possible impact with terrain." The investigation into the Ethiopian Airlines crash is only just starting — so aviation experts say it's way too early to try and  draw too many comparisons  between the two incidents.   The FAA and NTSB will be assisting local authorities with the probe, since Boeing is based out of Chicago.

Boeing announced Monday that it has no plans to immediately issue new guidance for its 737 MAX 8 aircraft.
