Ethiopian Airlines black boxes show similarities to Lion Air crash: ministry
Ethiopia said on Sunday the crash of an Ethiopian Airlines plane that killed 157 people had “clear similarities” with October’s Lion Air crash, according to initial analysis of the black boxes recovered from the wreckage of the March 10 disaster, Trend reports citing Reuters.
Both planes were Boeing 737 MAX 8s, and both crashed minutes after take-off after pilots reported flight control problems. Concern over the plane’s safety caused aviation authorities worldwide to ground the model, wiping billions of dollars off Boeing’s market value.
Investigators are trying to determine why the aircraft plunged into a field shortly after take off from Addis Ababa, searching for possible similarities to an October Lion Air crash that killed 189 people.
“It was the same case with the Indonesian (Lion Air) one. There were clear similarities between the two crashes so far,” Ethiopian transport ministry spokesman Muse Yiheyis said.
“The data was successfully recovered. Both the American team and our (Ethiopian) team validated it. The minister thanked the French government. We will let you know more after three or four days,” he told Reuters.
In Washington, however, US officials told Reuters that the US Federal Aviation Administration and US National Transportation Safety Board have not validated the data yet.
When investigators, after reviewing black box data, return to Addis Ababa and start conducting interpretive work, the NTSB and FAA will assist in verification and validation of the data, an official said.
A second source said little information had been circulated between parties about the contents of data and voice recordings.
It was not clear how many of the roughly 1,800 parameters of flight data and two hours of cockpit recordings, spanning the doomed 6-minute fight and earlier trips, had been taken into account as part of the preliminary Ethiopian analysis.
It is not unknown for the broad reasons for a crash to be understood in the hours after data has been recovered, but experts say fuller analysis is usually needed too.
The crash has generated one of the most widely watched and high-stakes probes for years, with the latest version of Boeing’s profitable 737 workhorse depending on the outcome.
Previous accident reports show that in such high-profile cases there can be disagreements among parties about the cause.
In Paris, France’s BEA air accident investigation agency said data from the jet’s cockpit voice recorder had been successfully downloaded. The French agency said in a tweet it had not listened to the audio files and that the data had been transferred to Ethiopian investigators.
In Addis Ababa, a source who has listened to the air traffic control recording of the plane’s communications said flight 302 had an unusually high speed after take-off before the plane reported problems and asked permission to climb quickly.
