There is basically no gap in the black box of foreign air crashes from search to analysis, and part of it is due to Xu Qing's recent out-of-control incident. Within half a month, there were major safety problems with the same model, which made the civil aviation department of the country where the incident occurred pay special attention, and the casualties of the air crash were extremely heavy, so the civil aviation department of the country where the incident occurred was also under great pressure.

After almost round-the-clock efforts, analysis of the black box showed that the maneuvering characteristics enhancement system was activated five times after the flaps were closed, after which the pilot pressed the stabilisation shut-off gate to the cut-off position, in accordance with Boeing's recent technical notice on turning off the maneuvering characteristics. But the strange thing is that not long after the stabilizer trim was cut off, the unit turned on the stabilizer cut-off door again.

Since the Maneuvering Augmentation System was activated five times, and the crew in question acted in accordance with Boeing's recent technical announcement, it is likely that the Maneuvering Augmentation System has malfunctioned again.

Now it is puzzling why the unit concerned has reopened the stabilizer cut-off valve after placing it in the cut-off position, and what is the motivation of the unit to do so?

The analysis data of the black box also pointed out a problem, at that time, the airspeed of the aircraft had reached 320 knots, which was relatively close to the limit speed. Could it be that at such high speeds, the excessive aerodynamic load makes it impossible for the unit concerned to use manual trimming.

The manual trim is difficult to rotate, and Xu Qing also encountered the out-of-control incident half a month ago. At that time, the speed of the plane was not very large, and the balance handwheel could barely turn once, if it was an airspeed of three hundred and twenty knots, then the strength required to turn the balance handwheel would be much greater than that of Xu Qing at that time.

This is just speculation by relevant experts, and the specific reason will have to wait for a detailed analysis of the data later. However, judging from the preliminary investigation results, the black pot of the maneuvering characteristic enhancement system may not be removed.

On the day of the release of the preliminary investigation report of the foreign air crash, the bureau contacted the chief pilots of all domestic airlines and held an urgent video conference. The meeting conveyed basic information about the crash and the strong skepticism of relevant experts about the MAX maneuvering characteristic enhancement system.

In fact, it can now be judged that the cause is the maneuverability enhancement system, because all the pilot's maneuvers during the plane problem revolve around this system. It's just that it's still unclear how this system led to a tragedy even when the pilot had been told what to do with it.

As it stands, it seems that Boeing's technical announcement on the Maneuvering Characteristics Augmentation System does not fully address the side effects of the system's false start-up.

After informing the chief pilots of the companies of the details of the accident, the bureau focused on the chief engineers of several airlines with MAX models, including Blue Airlines and China Airlines.

During the meeting, the bureau announced the suspension of the operation of the MAX aircraft and the resumption of operation pending the notice of the bureau. When the bureau announced this decision, the chief engineer of China Airlines had a face as black as the bottom of a pot.

In fact, without the need for the bureau to suspend the operation of MAX aircraft, the marketing department of all airlines with MAX models has already become a mess.

Now is the era of information explosion, and the civil aviation departments of the countries that crashed abroad are not hiding, and such a big thing cannot be hidden. All information will be released as soon as possible.

At least before the bureau's video conference, news about the air crash investigation report was already flying all over the Internet. Half a month ago, the domestic MAX runaway incident was still on the hot search! The old is not far away, and the new has arrived in a hurry. In less than half a day, half of the hot search list on the Internet was occupied by the topic of MAX. Almost as soon as everyone expected, Boeing's reputation collapsed.

The 737 MAX, Boeing's "crowning product", has been demonized overnight. Airlines with MAX aircraft experience a large number of refunds, and almost all refunds are concentrated on MAX flights. Even if the airline announced that it would change the aircraft type to carry out the flight, it still could not reverse the avalanche of refunds.

Even if the bureau does not suspend the operation of the MAX aircraft, at least in the near future, the MAX model will be put into the cold.

When Chief Engineer Wang Liang finished the video conference of the bureau, he went to the president's office to convey the spirit of the meeting as soon as possible. Even though Wan Qian was mentally prepared, he was still shocked when he really heard that the bureau had decided to suspend the operation of MAX.

Blue Sky Air is one of the companies that has suffered a wave of refunds, but fortunately, there are not too many MAX flights in Blue Sky, and the losses are not so big. The people's memory is short-lived, and after the MAX incident subsides, MAX will gradually be accepted by the people.

Which aircraft type has not had a serious air crash? It's not like it's still flying well. It's just that the time interval between the two MAX events is too short, and the faults are concentrated in one point, that such a violent anti-MAX wave will occur. As long as Boeing can deal with the MAX flaws and keep it running safely, the MAX can still be a good model.

But now that the bureau has suspended the MAX operation, and it looks like it will remain in this state for a short time, this is quite annoying news.

The suspension of MAX services means that even after the passage of time, the public has gradually cleared their concerns about MAX, but airlines are still unable to use MAX carriers. This news is undoubtedly fatal for China Airlines, which has a huge MAX fleet.

Not to mention the large amount of MAX storage costs, it is to fill the hole in the MAX outage, which will definitely affect other flights. Even Wan Qian, who knows the details of China Airlines, knows that there is no east wall to tear down the current China Airlines.

It's really going to be a death for China Airlines!

Xu Qing, who had been wandering blindly with Li Xianyi, was really scared into a cold sweat after learning that the foreign air crash was really because of the maneuvering feature enhancement system. grabbed Li Xianyi and went to the temple to worship the old gods from all walks of life, half a month ago, he really picked up a life.

Yang Jiyue and Mei Tingting, who also learned about the foreign air crash investigation report, accelerated their pace, and now the impossible is really going to be turned into a possibility.

In addition to contacting the Li family, Yang Jiyue directly told her father about her plan and asked her father to help consider it, after all, her debut was such a big move, even if Yang Jiyue was full of energy, she was still a little weak-hearted.

Yang Jiyue's father was also shocked when he heard that his daughter had come up with such a big plan without saying a word. Yang Jiyue's operation to take Blue Sky Air from China Airlines is tantamount to a tiger's mouth, but it is not impossible with proper operation. The key still depends on the attitude of the Li family and the Mei family.

If the Li family and the Mei family are willing to join forces, then the success rate of this plan will increase greatly, and at the same time, under Yang Jiyue's soft grinding and hard bubbles, he has to go to several other houses to walk around, and stabilize the people who want to insert a bar.
