Investigators have found the flight data recorders from an Ethiopian Airlines plane that crashed on Sunday.
The devices recovered at the crash site where the Boeing 737 Max 8’s cockpit voice recorder and digital flight data recorder.
The plane was en route from Addis Ababa to the Kenyan capital, Nairobi, when it crashed six minutes after take-off, killing all 157 people on board.
The months-old aircraft came down near the town of Bishoftu, 60km (37 miles) south-east of the capital at 08:44 local time (05:44 GMT).
Several airlines have grounded the Boeing model following the disaster.
China, Indonesia and several airlines around the world have grounded the 737 MAX 8 after a second crash involving the best-selling Boeing aircraft in less than five months.
Chinese aviation authorities on Monday told airlines in the country to ground all their Boeing 737 MAX 8 aircraft, citing the need for “strict control of safety risks.”
Regulators in Indonesia said that planes there would need to be inspected before flights resumed. Some individual airlines are taking similar action elsewhere.
US and European Union regulators also said they are closely monitoring the situation, but they have not yet taken steps to inspect or ground 737 MAX fleets.
But Mary Schiavo, a CNN aviation analyst, and former inspector general for the US Transportation Department said it would be a good idea for Boeing or the airlines to ground the planes ahead of any government mandate.
