On the 4th, the Ethiopian Ministry of Transport issued a preliminary investigation report on the air crash of Ethiopian Airlines on March 10, which showed that the speed of the Boeing 737 MAX 8 passenger plane before the crash was much higher than the upper limit of operation, and the qualification of the passenger plane pilot was qualified and operationally compliant.
On the same day, the CEO of Boeing apologized for the two crashes of Ethiopian Airlines and Indonesian Lion Air, acknowledging that there was a problem with the flight system.
Boeing CEO Dennis Millenberg said on the social networking site that he apologized for the 346 deaths of Indonesian Lion Air and Ethiopian Airlines Boeing 737 MAX 8 aircraft in the past six months.
He said, "Boeing apologizes for the loss of life in the recent 737 MAX passenger plane accident. These tragedies continue to be heavily weighed in our hearts. We have passengers and crew on our 610 flights and the 69 flights of Ethiopia Airlines. The relatives of the staff expressed condolences."
Millenberg used the word "error" many times, acknowledging that certain passengers had misreading specific sensor readings before the crash, causing the passenger aircraft flight attitude correction system to "wrong start".He promised that Boeing will carefully read the preliminary report of the Ethiopian air disaster investigation issued by Ethiopia on the same day and take all necessary steps to strengthen the safety of passenger aircraft.
The preliminary investigation report of the Ethiopian air disaster that was released on the same day showed that the pilot of the crashed passenger plane had not been able to manually stabilize the aircraft after the aircraft had a dive.The report said that before the crash, the speed of the passenger plane had reached 926 kilometers per hour, much higher than the upper limit of the operation of the 737 MAX 8. Until the tragedy occurred, the pilot was still unable to successfully control the aircraft.
Ethiopian Transport Minister Dagmarvit Moggs said at the press conference to introduce the results of the initial investigation of the air crash. The report pointed out that the pilot followed all emergency procedures recommended by Boeing before the crash. The pilot had a Boeing 737 MAX 8 passenger aircraft. Qualifications and experience, operations are in line with specifications.Moggs said, "The crew repeatedly operated all the procedures provided by the aircraft manufacturer, but still could not control the passenger aircraft."
In addition, Moggs said that the airworthiness certificate of the crashed passenger aircraft did not expire; the aircraft showed normal when taking off, and the weather conditions were normal on the day of the incident, and urged Boeing to re-evaluate the flight control system of the crashed passenger aircraft model.
However, this report does not give a detailed analysis of the crash of the passenger plane, because the full analysis takes at least several months.
