In two anonymous reports on flights just after the Lion Air disaster, United States pilots disconnected the autopilot and corrected the plane's trajectory in response.
According to The New York Times, air traffic controllers observed the Ethiopian Airlines plane "oscillating up and down by hundreds of feet" prior to the crash.
Ethiopian Airlines CEO Tewolde GebreMariam said the doomed flight's captain was an experienced aviator with more than 8,000 flight hours. "I'm climbing back up", he said in the simulator. Addis Ababa is surrounded by hills and, immediately to the north, the Entoto Mountains.
In Paris, France's BEA air accident investigation agency said data from the jet's cockpit voice recorder has been successfully downloaded.
The plane crashed minutes after taking off from an Addis Ababa airport bound for Nairobi.
"We are waiting for the results".
In the meantime an Ethiopian delegation has reportedly joined investigators in France who are probing the cause of last Sunday's Ethiopian Airlines Crash.
"This kind of investigation needs considerable amount of time to reach concrete conclusions". The United States and many other countries have grounded the Max 8s as the USA -based company faces the challenge of proving the jets are safe to fly amid suspicions that faulty sensors and software contributed to the two crashes that killed 346 people in less than six months. Passengers from more than 30 nations were aboard.
Death certificates are expected to be issued in two weeks. Collection of DNA samples from relatives had begun. "I would like to emphasize his record and that he was a rising star at Ethiopian Airlines".
The Lion Air crash also came just minutes after takeoff, killing 189 people, and USA authorities say there is evidence of similarities between the accidents. All 189 people onboard were killed.
However, there have been reports from pilots that the system tip the aircraft's nose downwards within minutes of take-off, forcing them to step in to stop the plane from dropping.
The move came after a growing number of airlines and countries decided not to fly the planes or ban them from their airspace until it is determined there are no safety issues.
"Safety is Boeing's No. 1 priority and we have full confidence in the safety of the 737 Max", the statement read.
The U.S. planemaker has been working on a software upgrade for an anti-stall system and pilot displays on its fastest-selling jetliner in the wake of the deadly Lion Air crash.
