Ethiopia said the black boxes of the crashed planes had similarities with the Lion Air disaster

The crash of an Ethiopian Airlines plane that killed 157 people had "obvious similarities" with the crash of Lion Air in October, revealed Sunday Ethiopia, revealed by a first badysis of the boxes blacks found after the disaster of March 10.

The accident has generated one of the most-watched and high-stakes surveys in years, with the latest version of Boeing's profitable 737 product depending on the result.

Both aircraft were equipped with MAX 8 and crashed a few minutes after take-off, after the pilots reported flight control problems. Concerns about the safety of the aircraft have led civil aviation authorities to found the model, erasing billions of dollars from Boeing's market value.

"It was the same case with the Indonesian (Lion Air). Up to now, the similarities between the two accidents were obvious, "said spokesman of the Ethiopian Ministry of Transport, Muse Yiheyis.

"The data has been recovered successfully. The US team and our (Ethiopian) team have validated it, "he told Reuters, adding that the ministry would provide more information after three or four days.

In Washington, however, US officials told Reuters that the FAA and the US National Transportation Safety Board (NTSB) had not yet validated the data.

Boeing's safety badysis of a new flight control system, called MCAS on MAX jets, included several critical flaws, including underestimating the power of the system, the Seattle Times reported on Sunday.

The FAA also did not investigate further and did not follow a standard MAX certification process, according to the newspaper, citing an FAA spokesperson.

The FAA declined to comment on the report but referred to earlier statements regarding the certification process. He said the process follows the standard FAA process.

Citing people familiar with the investigation, the Wall Street Journal said Ministry of Transportation officials were reviewing the FAA's approval of MAX jets and a grand jury in Washington, DC had issued a summons to appear. to at least one person involved in the development of MAX.

The March 11th summons – a day after the crash of Ethiopian Airlines – was a contact between a criminal division prosecutor at the Justice Department and requested that documents be delivered later this month, the statement said. newspaper.

It was not clear beforehand whether the DoJ summons was related to the DoT investigation, which was about MCAS, involved in the Lion Air crash that killed 189 people, the report said. WSJ.

Boeing and the FAA declined to comment on the WSJ report.

Two government officials informed of the issue told Reuters that it would not be surprising that the transport department is investigating a major security problem, but they could not immediately confirm the report.

SECURITY ANALYSIS

A senior official told Reuters that when the investigators – after examining the Ethiopian Airlines crash black box data – returned to Addis Ababa for interpretation work, the NTSB and FAA would participate in the search. verification and validation of data.

A second source said that little information had been distributed between the parties on the content of the data and voice recordings.

In the Ethiopian preliminary badysis, it was unclear how much of the approximately 1,800 flight data and two hours flight recordings in the badpit, covering the six-minute convicted robbery and previous trips , had been taken into account.

International rules require that a preliminary report on the accident be published within 30 days.

Previous air crash reports show that in such high-profile cases there may be disagreements between the parties about the cause.

In Paris, the French Air Accident Investigation Agency BEA stated that the badpit voice recorder data had been successfully downloaded. The French agency said on Twitter that she had not listened to the audio files and that the data had been transferred to Ethiopian investigators.

In Addis Ababa, a source who listened to the air traffic control record of aircraft communications stated that flight 302 had an unusually high speed after take-off before reporting problems and asking for air traffic control. authorization to go up quickly.

Last Monday, Boeing, whose shares have fallen 10% in the week since the accident, announced that it would roll out a software upgrade to the 737 MAX 8, just hours after the FAA announced that It would impose "design changes" to the aircraft by April.

Boeing was finalizing the software change and a review of the training and would evaluate the new information as soon as it was available, said Chief Executive Officer Dennis Muilenburg in a statement released Sunday after ministry comments. Ethiopian Transport.

A spokesman for Boeing said the 737 MAX was certified to meet the same FAA requirements and processes that governed the certification of all new aircraft and derivative products. The spokesperson said the FAA had concluded that the MCAS on the 737 MAX meets all certification and regulatory requirements.
