Security investigators will release a much-anticipated preliminary report on Thursday on the deadly crash of Flight 302 of Ethiopian Airlines, providing the first official clues on the cause of the disaster.
The new Boeing 737 MAX 8 crashed on the morning of 10 March, after taking off from Addis Ababa to Nairobi, Kenya, killing 157 people on board.
The disaster was the second such accident caused by a Max 8 aircraft in less than six months and had resulted in the grounding of the aircraft around the world.
In October, the 189 passengers on Lion Air Flight 610 were killed when the flight flew over the Java Sea in Indonesia 13 minutes after take-off.
The Federal Aviation Administration agency stated that it had similarities identified between the crash of Ethiopian Airlines and that of Lion Air in Indonesia.
At the center of the investigation is a flight control feature, called the Maneuverability Enhancement System (MCAS), installed on both aircraft.
The MCAS is a system that automatically lowers the nose of the aircraft when it receives information from its external attack angle sensors (AOA) indicating that the aircraft is flying too far slowly or too strongly and may stall.
The report is the first report submitted by the airlines after the disaster and must be produced by the investigating authority within 30 days of an incident.
