Boeing has been under increasing pressure for failing to brief airlines and pilots on its 737MM 8 aircraft, which has been found to be "catastrophic."
The pressure is focused on the company's acknowledgment that it has not notified anyone related to the model aircraft, updates and modifications it added, nor the potential risks of adding these modifications.
Indonesia's Leon Air, whose aircraft crashed 13 minutes after the undisclosed modifications, joined two US pilots and other aviation officials in criticizing Boeing.
A Lyon Air official accused Boeing of failing to inform the pilots about the potential dangers of the safety system that it added to the aircraft, causing the jet crash and landing in the Java Sea less than a quarter of an hour after it was taken off and all those aboard were killed.
Boeing's Boeing 737 Max 8 and 9 had no information at all on the automatic braking system, which aims to help pilots avoid seriously raising the front of the aircraft, said Boeing's Chief Operating Officer Zwingli Selahi. By mistake, which could push the aircraft in unusual circumstances to dive suddenly and strongly so that the pilot can not return to the horizontal position again.
He explained that the guide failed to alert the pilots that the added safety system may in some cases lead to a mechanical response including reducing the front of the aircraft, adding: "That is why we do not have special training for this situation specifically."
A number of airlines, pilots associations and flight training departments have realized that there is no documentation of any type in the aircraft manual explaining the new system.
US pilots have confirmed that they do not know about the risks of the new security system on the Boeing 737 Max 8 and 9, and John Wicks, head of the Southwest Tourists' Union, told Bloomberg on Tuesday that he and his colleagues in the union did not know either. .
"Boeing did not provide us with any information we could rely on when flying our aircraft," said Dennis, a spokesman for the American Pilots Union. "We did not get any information from Boeing or any regulator about additional training for our pilots."
