Ethiopia and Indonesia crash parallels heap pressure on Boeing
Investigators into the Boeing Co 737 MAX crash in Ethiopia have found striking similarities in a vital flight angle with an airplane that came down off Indonesia, a source said, piling pressure on the world’s biggest planemaker.To get more finance news, you can visit shine news official website.

The Ethiopian Airlines disaster eight days ago killed 157 people, led to the grounding of Boeing’s marquee MAX fleet globally and sparked a high-stakes inquiry for the aviation industry.

Analysis of the cockpit recorder showed its “angle of attack” data was “very, very similar” to that of the Lion Air jet that went down off Jakarta in October, killing 189 people, a person familiar with the investigation said.

The angle of attack is a fundamental parameter of flight, measuring the degrees between the air flow and the wing. If it is too high, it can throw the plane into an aerodynamic stall.

“If that’s the case, that does raise the possibility that there is a similar occurrence between the Lion Air and Ethiopian Airlines accidents,” said Clint Balog, a Montana-based professor at Embry-Riddle Aeronautical University. Even then, it was too early to draw firm conclusions, he added.

A flight deck computer’s response to an apparently faulty angle-of-attack sensor is at the heart of the ongoing probe into the Lion Air crash.

Ethiopia’s Transport Ministry, France’s BEA air accident authority and the U.S. Federal Aviation Administration (FAA) have all pointed to similarities between the two disasters, but safety officials stress the investigation is at an early stage.

“Everything will be investigated,” Ethiopian Transport Ministry spokesman Musie Yehyies told Reuters.Both planes were 737 MAX 8s and crashed minutes after takeoff with pilots reporting flight control problems.
