Boeing has grounded its entire global fleet of 737 Max aircraft after investigators uncovered new evidence at the scene of the fatal Ethiopian Airlines crash.
The US aircraft manufacturer has decided to suspend all 371 of the aircraft.
Although the Federal Aviation Administration (FAA) had previously held out while many countries banned the aircraft, they recently revealed that fresh evidence as well as newly refined satellite data prompted the decision to temporarily ban the jets.
Following the death of 157 passengers and crew in last Sunday's crash, Ethiopian Airlines have announced that the black box flight recorders from the aircraft have been flown to Paris for analysis. "An Ethiopian delegation led by Accident Investigation Bureau has flown the Flight Data Recorder and Cockpit Voice Recorder to Paris, France for investigation," the airline wrote on Twitter.
The FAA has a team investigating the disaster at the Ethiopian Airlines crash site working with the National Transportation Safety Board. Dan Elwell, acting administrator at the FAA, said on Wednesday: "It became clear to all parties that the track of the Ethiopian Airlines [flight] was very close and behaved very similarly to the Lion Air flight." He added that "the evidence we found on the ground made it even more likely the flight path was very close to Lion Air's".
President Donald Trump initially announced that the FAA would be making an emergency order following "new information and physical evidence that we've received from the site and from other locations and through a couple of other complaints".
The US and Brazil became the latest countries to suspend the Boeing 737 Max from flying after nations including the UK, China, India and Australia all grounded the aircraft.
Until Wednesday, the FAA position was that a review had showed "no systemic performance issues" and that there was no basis for grounding the aircraft.
