Ethiopian Airlines Pilots Follow Boeing Accident Before Crash: Report



Referring to unnamed sources familiar with the investigation, WSJ reported that, despite the steps that included turning off the automated flight management system, pilots could not return control over the Boeing 737 MAX 8.

CNN did not confirm the details of the report.

Earlier this month, the Federal Aviation Administration substantiated all of the Boeing 737 Max aircraft, claiming they found similarities between the crash of the Ethiopian Airlines and the Lion Air catastrophe in Indonesia six months earlier.

The Ethiopian Airlines flight 302 crashed on March 10 after it departed from Addis Ababa on its way to Nairobi, Kenya, killing 1

57 people aboard.

The 610 Lion Air flight crashed into the Javanese Sea in Indonesia on October 29 after it departed from Jakarta. All 189 people aboard died.

After the Lion Air disaster, Boeing issued an Operating Manual Bulletin "Aviation Operators Counseling How to Solve The airline said that "the existing flight crew procedures are turning to circumstances in which there is an erroneous input from the AOA sensor (the angle of attack)," Boeing says.

If verified, the results presented in Wall Street Journal, suggest, the following extraordinary procedures in the Boeing Handbook may not be sufficient to prevent a collapse.

The incoming messages derive from the preliminary report required by the investigating authority and to be provided within 30 days of the incident. The findings are not final and may be changed as the investigation continues

Others reported preliminary data from data received from the black box of the jet plane Ethiopia, suggest that the flight control function called ma evryruyuschey System (MCAS), automatically activated before the accident.

MCAS is a system that automatically lowers the plane's nose when it receives information from its external attack angle sensors (AOAs) that the plane is flying too slowly or steeply and risks to stop.

The Lion Air crash, the MCAS forced the plane to carry down more than 24 times before it finally hit the water, according to a preliminary investigation by the Indonesian National Transportation Safety Committee, which also found the system in line with a faulty sensor.

The researchers pointed out whether pilots had sufficient training with the system.

According to the CEO of Ethiopian Airlines, Tevolde Hebremariam, pilots who switched to the Boeing 737 Max 8 from the older 737 models should only have a short computer training program designed by Boeing and approved by the FAA.

GebreMariam also said that the flight simulator, which pilots learned to fly on the Boeing 737 Max 8, did not reproduce the automated MCAS function that researchers are investigating. – which one pilot told CNN what he took on his iPad – highlighted the differences between Max 8 and older 737, but did not explain MCAS's function.

Boeing said it was working on a software patch for 737 MAX jets, but the FAA said on Monday that the company had completed "required additional work."

"FAA expects to receive the final Boeing package from its software in the coming weeks for the FAA." – The agency said in a statement. "Time is required for Boeing's additional work as a result of the ongoing review of the air traffic control system 737 to ensure that Boeing has identified and duly dealt with all relevant issues."

A new investigation by the Senate began on Tuesday Reports of the disclosers raised the question of whether the FAA inspectors who had reviewed the certification of the Boeing 737 MAX were duly trained.
