Eight days ago, 157 people were killed in the air crash in Egypt, which led to the global grounding of Boeing MAX series aircraft, thus confronting the aviation industry with a stakeholder investigation.
According to people familiar with the investigation, the analysis of the cockpit call recorder shows that the data of the plane's Angle of Attack (AOA) is "very, very similar" to the plane that crashed in Jakarta in October by Lion Airlines Indonesia.
Angle of attack is one of the basic flight parameters, which measures the angle between airflow and wing. If the angle of attack is too high, the airflow may cause stall.
"If this is the case, there may indeed be similarities between Lion Airlines and Aeronautical Aviation," said Clint Balog, a professor at Abridged University of Aeronautics. Even so, he adds, it is too early to draw clear conclusions.
The response of the cockpit computer to the obviously defective angle-of-attack sensor is the core of the ongoing Lion Aviation Difficulty Survey.
The Ethiopian Ministry of Transport, the French Aeronautical Accident Investigation Agency (BEA) and the Federal Aviation Administration (FAA) of the United States all pointed out the similarities between the two accidents, but security officials stressed that the investigation was still in its infancy.
"We need to investigate all aspects," Musie Yehyies, a spokesman for Ethiopia's Ministry of Transport, told Reuters.
