Boeing CEO admits to making mistakes on 737max

On October 29 local time, on the first anniversary of the lion air crash in Indonesia, Boeing CEO millenberg attended the Senate hearing of the United States Congress. Millenberg admitted that the Boeing 737max made a mistake in design, 'we made a mistake, we made something wrong.' Previously, there were two air crashes on Boeing 737max, killing 346 people. Some congressmen said, "I would rather walk than take 737max.".

On October 29, one year ago, an Indonesian lion Airlines Boeing 737 max8 aircraft numbered jt610 crashed into the sea more than 10 minutes after taking off at Jakarta International Airport, killing all 181 passengers and 8 crew members on board.

Just five months later, 149 passengers and 8 crew members on Ethiopia Airlines et302 were also killed. The accident model was also 737max. The two air crashes banned the global aviation management department from flying 737max, forcing Boeing to face up to the problems of its best-selling model.

'on behalf of myself and Boeing, we are sorry, we apologize, we made mistakes and did something wrong.' Dennis & middot, CEO of Boeing; At the hearing of the Senate Committee on commerce, science and transportation on October 29, millenberg admitted that Boeing made mistakes in developing the 737 Max aircraft and the safety assessment was not in place.

This is the first time Boeing executives have admitted to the public that Boeing has made a mistake. After apologizing, will it affect the go around of 737max?

Lion Airlines air crash report pointed out that system problems were the main cause of the air crash

Four days before the hearing, on the afternoon of October 25, Indonesia's National Transportation Safety Commission (knkt) held a press conference at its headquarters in Jakarta and released the final investigation report on the crash of lion Airlines passenger plane jt610 into the sea.

The report shows that the design and certification of anti stall maneuverability enhancement system (MCAS) for the crashed Boeing 737 max8 airliner did not fully consider the possibility of aircraft out of control. Boeing's MCAs design allowed the adjustment angle of the aircraft's horizontal tail to be increased from 0.6 degrees to 2.5 degrees, and this change was not updated in the relevant documents submitted to the Federal Aviation Administration (FAA), so FAA failed to reassess the safety of the design change.

The report said that Boeing failed to provide any information about the MCAs system to the pilots, resulting in the crew being unable to understand the situation in time at the critical moment. Since there is no information about MCAs system in the aircraft manual and pilot training, it is difficult for the crew to diagnose the problem and take corrective measures in time.

The report shows that the angle of attack sensor of the crashed aircraft has failed, and MCAs system has made wrong adjustment according to the wrong sensor data. Similar sensor failures occurred in the flight the day before the crash, but lion Airlines did not grounded the plane.

The report said that the two pilots of the crashed flight had insufficient adaptability, especially the co pilot was not familiar with the operating procedures. After the aircraft system failed and successfully resisted the aircraft dive for 20 times, the captain handed over the power to operate the aircraft to the nervous co pilot at that time, who did not maintain the ability to operate the aircraft at that time, and then the aircraft crashed into the sea.

Finally, the report recommends that Boeing redesign the MCAs system and introduce error proofing design. In the design, the impact of all possible cockpit alarms and indications on pilot identification and response should be considered; Considering the abilities of different pilots, various pilots can operate; At the same time, relevant MCAs system information shall be included in the pilot manual and training.

This air crash report is equivalent to pointing out that the problem of the 737max system is the main cause of the air crash. For a long time, Boeing has not directly recognized that its aircraft is responsible for the air crash, and called its improvement efforts after the 737max was grounded globally 'making the already safe aircraft safer'.

However, at the hearing on the 29th, Dennis & middot; Millenberg admitted for the first time, 'we made mistakes and we did something wrong.'. When asked why the 737max was not grounded after the lion air crash, millenberg said, "if we can go back to the past, we will make a different decision."

Members called the 737 Max a 'flying coffin', and aviation regulation was questioned

At the more than two-hour hearing, many senators of the Senate business committee asked millenberg questions on Boeing 737 Max flight control software, Boeing's interest connection with the Federal Aviation Administration (FAA), etc.

Senator Tammy middot of Illinois; Dakworth questioned that Boeing had not fully disclosed the details of the lack of security of the 'mobility enhancement system (MCAS)' and criticized that 'you have told me half truth again and again'. Senator Richard middot of Connecticut; Blumenthal called the 737 Max a 'flight coffin' and questioned Boeing's previous attempt to shift the responsibility for the crash to the pilot.

At the hearing, senators also questioned the weak aviation regulation exposed by the two air crashes. In the process of Boeing 737max safety assessment, the Federal Aviation Administration, which should bear the regulatory responsibility, 'outsourced' some assessment tasks to Boeing, allowing Boeing to complete the safety certification of its own passenger aircraft. Senator Jon middot of Montana; Tessa pointed out that if the FAA had done its job all the time, the air crash would not have happened.

On October 18, the U.S. Federal Aviation Administration (FAA) released a report that according to an exposed communication record, two Boeing pilots found that there were potential safety hazards in the flight control system of 737 Max aircraft as early as 2016, but this problem was not reported to the regulatory authority in time.

The FAA said that Boeing had discovered the communication record several months ago, but it was not until the evening of October 17 that Boeing informed regulators of the existence of the record.

Millenberg said at the hearing that he only learned about it recently and didn't know it before. For Boeing's replacement of FAA for safety assessment and certification of new aircraft, millenberg said that Boeing is willing to make adjustments in the assessment and certification.

Millenberg also stressed that after the air crash, Boeing has been trying to correct the errors existing in the previous Boeing 737 Max model. At present, the relevant work has entered the final stage. Boeing hopes that the aircraft will be allowed to go around again by the end of this year.

737max missed approach indefinitely?

At the hearing on the 29th, millenberg also focused on how to improve the model. Millenberg said that Boeing has invested all necessary resources to ensure the comprehensive and thorough test and improvement of the 737max. He said that 814 test flights have been carried out with the latest software, And conducted several simulation training with 545 participants from 99 customers and 41 global regulators. We hope to make the 737 Max go around as soon as possible.

In fact, in the past few months, Boeing has also communicated with mainland airlines and pilots in many places in China, hoping to promote 737max go around as soon as possible.

"We know we have made mistakes and made some mistakes." Millenberg said at the hearing that Boeing had learned a profound lesson.

However, Boeing's efforts, not only the Civil Aviation Administration of China did not make any relevant statement, but many foreign airlines even postponed the go around plan of 737max again.

Air Canada said it would extend the decision to grounded Boeing 737max until February 14, 2020. American Airlines said it would extend the grounding of Boeing 737max until mid January next year.

Patrick KY, director of the European aviation safety agency, said that European regulators would approve Boeing 737max to resume operation as early as or in January next year. It is expected that test pilots will conduct European flight tests in mid December this year.

After the outbreak of the concealment scandal, several agencies downgraded Boeing. Bank of America Merrill Lynch lowered Boeing's target price from $400 to $370. UBS downgraded Boeing from buy to neutral with a target price of $375. Credit Suisse downgraded Boeing's rating from outperformance to neutral, with a target price of $323.

On October 29, Boeing's share price was $348.93, up 2.36%.

On the other hand, according to a detail described by CNN, after more than two hours of hearing, a family member of the Ethiopian air crash victims questioned millenberg: 'Mr. millenberg, can you turn around and look into our eyes when you say you apologize?' Hearing this, millenberg turned to the family and whispered, 'I'm sorry.'
