Boeing’s leadership knew about the type-defects of the 737 MAX aircraft one year before the Indonesian aircraft disaster last autumn, but he listened to them – he wrote in The Wall Street Journal’s Sunday edition.

According to the information in the paper, the factory managers had already detected the problems after the production of the first models but had not been notified to the Federal Aviation Authority (FAA). Even after the disaster of the Lion Air airline in Indonesia last October, the information was shared with only a few airlines and a few pilots, but only partially, said The Wall Street Journal.
Only five days later, after the crash of the Ethiopian airplane next to Addis Ababa, the relevant officers of the factory began to talk about security flaws, but it wasn’t revealed to the public that it was a software bug in the background. He had to wait another six weeks before it was released. Referring to the FAA spokesman, the paper said that the head of the aviation authority was not aware of all this.
The paper highlights that the length of time between the detection and disclosure of errors is now published for the first time.
The Wall Street Journal says that both the FAA and the Chicago aircraft factory senior staff are increasingly concerned about how transparent Boeing is, to what extent they have deliberately been listening to security flaws in the cockpit.
Meanwhile, criminal investigation has also begun to investigate whether Boeing has misled and, if so, deliberately misled investors and customers. In the course of the investigation last week, the investigations had already covered how the aircraft of the type in question could be licensed and what their role was for Boeing leaders. On Sunday, the Boeing Leadership Announcement announced that their engineers identified in 2017 that the cockpit alarm system did not work due to a software error. The company’s managers and engineers then ordered an internal investigation, but found that this failure did not jeopardize flight safety. According to the corporate announcement, this top-level management was not aware of this internal investigation. It was only 29 October 2018, after the fall of the Indonesian Lion Air, that it became known to him, said the communiqué.
The conclusions of the internal investigation were shared by the company managers with the middle management of the FAA, but according to the FAA spokesman, after analyzing the situation, they also concluded that there was no need for immediate action.
At a meeting of Boeing’s shareholders on April 29, Dennis Muilenburg, CEO of the company, who was otherwise confirmed by the shareholders, said the company was focusing on enhancing aviation safety, and that there would be fully operational alarm systems on 737 MAX machines.
