Addis Ababa, Ethiopia - French aviation experts began work Friday on the heavily damaged data and voice recorders from Ethiopian Airlines flight 302, the airline said, while new revelations have suggested new links with an earlier crash in Indonesia involving the same type of aircraft.
The two so-called "black boxes" arrived at France's Bureau d'Enquêtes et d'Analyses, which has extensive experience analysing crashes, on Thursday. Germany had earlier turned down the opportunity to examine the recorders.
The data extracted from the recorders will be used to reconstruct the six-minute flight before the Boeing 737 Max 8 crashed into a farm field about 40 miles from Addis Ababa, killing all 157 passengers and crew, including the voice communication of the pilots and the readings of the various sensors.
The crash of another Max 8 aircraft into the Java Sea last October has been attributed in a preliminary investigation to a faulty sensor causing an automated system to push the nose of the plane down. The possibility that the same scenario occurred in Ethiopia has prompted precautionary groundings of the plane all over the world.
Bloomberg and several other media outlets cited investigators in the United States saying a device that sets the aircraft's trim was found in the wreckage and it was in position to force the airplane down - another similarity with the Indonesian crash.
