Boeing said he expects the problematic 737 Max aircraft to return to the sky before the end of the year.

The jet landed after two fatal crashes, including the Lion Air disaster, where 189 people died a year ago.

But Boeing said Indonesian investigators developed a software update several hours after blaming a mechanical and design problem due to a crash.

It is working with regulators to get the jet back on track.

Boeing Finance Minister Dennis Muilenburg said, "Our top priority remains the safe return of the 737 Max and is making steady progress."

The company has also developed a training update and expected to allow the plane to take off again in early 2020.

"We have taken steps to further strengthen the company's focus on product and service safety, and we will always keep our promises and always seize new opportunities through the values ​​of safety, quality and integrity," Muilenburg said. Said.

Design issues

The statement was made a few hours after it was announced in October that mechanical and design problems in Indonesia's flight control system were one of the causes of Lion Air crash.

The researchers killed 189 people, focusing on the system used to improve handling of the Boeing 737 Max and prevent stall.

The 737 Max model started after the Ethiopian airline accident in March 2019.

On Tuesday, Boeing's Kevin McAllister was deported.

Boeing did not comment on the official report of the Lion Air crash after 13 minutes of takeoff from Jakarta on October 29, 2018.

The grounding of the 737 Max impaired the financial results of the plane maker in the third quarter. Profit fell by more than half to $ 855 million and blamed trade uncertainty, saying it would cut the production of the 787 Dreamliner.

On Tuesday, Boeing said that McAllister, the chief executive of Boeing's commercial aircraft, was the chief executive to leave after two crashes, killing a total of 346 people.

Muilenburg, CEO of Boeing, was deprived of chairmanship of the board this month and must explain what the company knows about issues related to the 737 Max.

The final report on the Indonesian investigator's Lion Air crash incident is expected to be released on Friday, but the overview provided to affected families is a major issue with the Manoeuvring Specialty Reinforcement System (MCAS) designed to make it easier to fly an aircraft. .

According to the report, families were told that there were false assumptions about how the MCAS control system works and that "defects" were highlighted during training.

The slide from the briefing to the family showed a lack of documentation on how the "stick shaker", a warning pilot of lift loss, works.

Reuters reports that a "stick shaker" warns of stalls for 13 minutes while the plane is in the air, and investigators believe this is based on incorrect data about the angle with the oncoming air.

The Indonesian National Traffic Safety Commission told families that MCAS would be a "contributing factor."

"Design and certification [737 Max]According to the AFP, assumptions have been made about pilot responses to malfunctions that are consistent with current industry guidelines but have been found to be incorrect.

The report found that the system relies on a single sensor for input and that the sensor that was replaced during the initial repair was "corrected".

When Boeing was certified in 2016, the question was raised as to how much Boeing knows about the 737 Max's issue since Boeing provided US lawmakers with documents that employees exchanged instant messages on MCAS-related issues.

The pilot wrote that he was "basically lying to the regulatory body," and an unexpected problem occurred during the test. [unknowingly]".

This document was provided ahead of Mr. Muilenburg's appearance before attending parliament next week.


The testimony of relatives of Lion Air 610 passengers raises more uncomfortable questions about the design of the 737 Max.

And I dive the plane incorrectly, focusing on the new flight control system of the aircraft known as MCAS.

Boeing and the regulators who signed the aircraft suggest that the assumptions about the performance of this system and how the pilot reacts are wrong.

All air accidents are a series of events, and according to the family, the behavior of the pilot was also a factor.

However, vulnerabilities in MCAS systems that previously relied on data from a single sensor are again receiving attention.

The departure of Kevin McAllister, who ran Boeing's commercial plane department, represents a bigger fallout.

Max is unlikely to return to the skies of the United States by the end of this year.

European regulators want to conduct further investigations, so they are likely to later certify the plane separately.

Why didn't you take more drastic steps after the Lion Air crash before the second accident killed 157 people and landed the plane globally?
