Chapter 77: This matter is unclear, I feel uneasy
Blue Sky Aviation cabin audio monitoring room.
This is where the safety supervision department and the quality center usually check the flight cabin sound. However, in this era, the company's requirements for flight cabin sound are not very strict. It is still far from the high-pressure state of later generations where people want to monitor the entire flight.
Because of this relaxed environment, the cabin sound monitoring room was mostly empty. But today there was someone inside, Boeing instructor Mo Shangyun.
He occasionally works part-time in the Safety Supervision Department or something. Today he was assigned to come here to listen to the cabin sound. There were no specific requirements, it was completely casual and he could listen as much as he wanted.
After listening to a few paragraphs, Mo Shangyun lost interest in listening any further. So he took out a stack of QAR data on paper and opened the audio on his phone, which turned out to be Xu Cang's voice.
After careful analysis, it turned out to be the recording of Xu Cang's commentary in the cockpit after he and Xu Cang came back from the make-up class at Lushui Airport. And the stack of information was the QAR data of the flight at that time.
He should have compared the recording and QAR data long ago, but was delayed by something. Today he happened to have nothing to do, so he decided to check and see if Xu Cang was talking nonsense.
The QAR data was very detailed, so Mo Shangyun compared it one by one with Xu Cang's recording.
"Radio altitude of one thousand feet, engine speed of fifty-four, descent rate of seven hundred and five. Radio altitude of five hundred feet, engine speed of fifty-three, descent rate of seven hundred, speed of one hundred and twenty-five..."
Xu Cang's voice sounded in the mobile phone player. After he finished speaking, Mo Shangyun paused first. Then he went to the QAR data to find the engine speed, descent rate and speed at the corresponding altitude.
Mo Shangyun worked part-time in the Safety Supervision Department, so it was easy for him to read the QAR data. He quickly found the relevant data: "Radio altitude of one thousand feet, engine speed of fifty-three, descent rate of seven hundred and five. Five hundred feet, speed of fifty-three, descent rate of seven hundred, speed of one hundred and twenty-four..."
The flight data on the QAR data were exactly the same as what Xu Cang said.
This is not the most terrifying thing. The most terrifying thing is that from the leveling stage, in that fleeting moment, the information Xu Cang provided was far more detailed than at a higher altitude.
From the aircraft's radio altitude, engine speed, changes in wind direction and speed, to the final change in the aircraft's attitude, in the short few seconds from leveling off to touching down, Xu Cang seemed to be able to stretch this time infinitely, and all changes became slow and clear.
"He has already graduated!" Mo Shangyun threw the information on the table and showed a bitter smile on his face: "He just got started, and then he graduated... This kid..."
As for when one can be considered to have mastered the skill of landing, Mo Shangyun has told his apprentices more than once: "When, starting from the fifty-foot leveling, your mind is no longer blank, and you can clearly perceive the changes in the aircraft's state and understand how to respond to the changes in state, then you have mastered the skill."
Many co-pilots who lack technical skills have a blank mind when they are about to touch down and just level the plane mechanically. Then what the final result will be depends on God's will.
However, Xu Cang had obviously managed to keep his eyes and ears open and remained calm.
Suddenly, Mo Shangyun's cell phone rang. He glanced at the number and quickly picked up the phone.
As the call was connected, a man's voice came from the other end: "Instructor, the 1566 aircraft you asked about earlier has been inspected and no problems were found. It has been approved to resume operation."
"No problem. Didn't the crew report an abnormal lift phenomenon?" During this period of time, Mo Shangyun was also somewhat concerned about Flight 1566, especially after Xu Cang's Jianchuan-Yingli flight, he became even more concerned.
He knew that the company had stopped 1566 for a period of time for inspection, which was considered to be quite serious, but he didn't expect that there was no problem after the inspection.
The people at the maintenance department were actually very puzzled. When they talked to Xu Cang's crew about the situation, the crew described it as horrific. However, after repeated checks, they didn't find any problems at all.
"I don't know about that. Anyway, we checked according to the procedures, and more than once." The person from the maintenance department considered his words and said, "Maybe it was an operational error by the crew at that time?"
"Really?" Mo Shangyun didn't say anything more and hung up the phone. After thinking for a long time in the chair, he finally sighed: "It turns out that he is not a god either."
…
At this time, in the office of Lu Jinghua, general manager of the flight department, he also received feedback from the maintenance department about aircraft 1566.
"That means there's nothing wrong with the plane, right?" Lu Jinghua confirmed with the maintenance department staff with a gloomy face.
The maintenance staff quickly replied: "Mr. Lu, we checked 1566 many times and found no problems."
Lu Jinghua hummed, said nothing more, and hung up the phone.
As the call was hung up, Xu Cang next to him asked impatiently: "Brother Lu, what did the maintenance department say?"
Lu Jinghua put his phone on the table and said weakly, "I checked many times and found that the plane was fine... and it was back in service."
"No problem, how could the plane be fine?" Xu Cang just found it unbelievable. The shock they experienced during takeoff was real.
Perhaps because he had experienced it personally, Xu Cang was a little excited, but Lu Jinghua didn't care much about it. Instead, he understood Xu Cang.
Jin Fuli, who was sitting on the sofa, advised: "Xu Cang, the maintenance staff has already reached a conclusion. Let's just forget about it. There is no result."
"Yeah, maybe Captain Zhu Jian was really driving too fast at that time?" Lu Jinghua also agreed.
Whether there is a problem with the aircraft is not decided by their flight department, but by the mechanics in the maintenance and support department. They can only passively accept this conclusion.
To be honest, this inspection is not a routine inspection, but an inspection specially designated by the company. It is an inspection carried out after the crew reported a serious problem. The maintenance department will definitely attach great importance to it and will not be perfunctory.
Moreover, if there is a problem with the plane, the maintenance personnel will not be able to escape responsibility afterwards. Anyone with a normal brain circuit would not play tricks on this.
Seeing that Xu Cang could not accept this result, Lu Jinghua added: "The maintenance staff told me that they checked and tested it more than once, and there is absolutely no problem."
"Absolutely no problem?" Xu Cang gritted his teeth and said, "Brother Lu, when I was evaluating the route before and it hit the tail, I felt that there was something wrong with the 1566 aircraft. So when I was flying with Captain Zhu Jian, I observed very carefully from behind. Captain Zhu Jian's action of holding the stick must be no problem..."
When Xu Cang was halfway through his words, Wang Xuan, who had been leaning against the door with his arms folded, suddenly said sinisterly: "What if your eyesight is not good enough to tell whether the rod is fast or not?"
"Impossible!" Xu Cang suddenly shouted, his emotions were extremely high. But he soon realized that he was too excited, and bowed slightly to Wang Xuan apologetically: "I'm sorry, Mr. Wang, I was just excited."
Wang Xuan just sneered and said nothing.
Although Xu Cang became the chief pilot of the General Administration in later life, he was often casual by nature. Because except for his mother's death due to illness in later life, he never encountered any real setbacks. Even though he was expelled from the 121st Department for being sloppy, he returned to the 121st Department with unparalleled talent, and then he was promoted all the way to become the fastest promoted chief pilot in the history of domestic civil aviation.
Unlike most officials, Xu Cang's behavior was indeed a bit careless. But in some major matters, such as flight safety, Xu Cang would never tolerate any problems.
Of course, Xu Cang is not a rigid person, and the so-called absolute safety is not in line with the logic of reality. However, the abnormal head-up problem like the 1566 aircraft is no longer a problem that can be ignored. It is a major event that may cause the aircraft to crash and people to die. As a result, the maintenance team reported that there was no problem with the aircraft. It was simply a huge joke!
Could it be that the terrifying scene between him and Captain Zhu Jian that day happened in a dream?
"Xu Cang, the maintenance staff has already made the decision and it cannot be changed. Also, I heard that the plane has been grounded for several days for inspection. The company really takes it seriously. Maybe there is really no problem." Jin Fuli said, "Or maybe the abnormal lift of the nose at that time was... affected by airflow? There is no need for the maintenance staff to lie about this."
Lu Jinghua followed up, "Yes, you are just a second mate, don't get involved in this matter."
"What if the fault is deeply hidden? What if this kind of ordinary inspection can't find it?" Xu Cang gritted his teeth and said, "What if something goes wrong again?"
Lu Jinghua patiently advised: "Xu Cang, the Boeing 737 is not as sophisticated as you think. Sometimes when the plane has a seizure, you can't find it no matter how hard you try."
It's not that Lu Jinghua deliberately belittled the Boeing 737 in order to persuade Xu Cang, but he felt from the bottom of his heart that the 737 was , just like a diesel tractor, which is tough and easy to use but also rough.
The systems in the Boeing 737 are complex and intertwined. If there is really a problem with a component causing the plane to lift abnormally, it is not impossible that the problem cannot be detected afterwards.
Such problems are usually quite rare. An airline can't just ground a plane forever because of an unidentified problem, right?
If you can choke to death while drinking water, you can’t just not drink water, right?
Xu Cang naturally knew that the 737 aircraft sometimes did have some inexplicable problems, but Xu Cang did not think that the problem of the abnormal nose lift was an isolated black swan event, but that the aircraft did have a fault, but it was hidden very deeply.
"Brother Lu!" Xu Cang pondered for a long time, and suddenly said, "What if we apply for a D check on aircraft 1566?"
"D...D inspection!" Lu Jinghua almost yelled, "Xu Cang, listen to me. It doesn't matter if you make trouble or complain to me here today. But, outside, you must never ask for a D inspection of plane 1566, especially to senior leaders."
Hearing that Xu Cang actually wanted 1566 to undergo a D inspection, Wang Xuan couldn't help but laugh: "Let him go and talk to him. It's best to talk to the vice president of maintenance. Only he can confirm the D inspection list."
Lu Jinghua was already upset, and when he heard Wang Xuan fanning the flames, he immediately became furious: "Wang Xuan, shut up!"
Jin Fuli was also frightened by Xu Cang, and hurriedly said, "Xu Cang, you can't talk about the inspection. It will violate taboos. The 1566 is a new plane. The normal inspection time is six years later. How can you inspect a plane that has been flying for less than a year? Moreover, the inspection cost alone is several million, and it will be grounded for nearly two months. The loss is too huge and horrible. No one will agree to it."
Xu Cang said coldly: "The cost of D inspection increases according to the age of the aircraft. 1566 is very new, so the cost should not be that high."
"Oh, you also know about the D inspection fee?" Wang Xuan smiled slightly: "Boss Lu, since he is so knowledgeable, just go along with him. Xu Cang, the third office on the right after the central elevator on the ninth floor is the vice president of maintenance. You can tell him your ideas and see how he responds."
Lu Jinghua shouted angrily: "Wang Xuan, get out of here!"
He had had enough of Wang Xuan's behavior of inciting Xu Cang's emotions, and at this time he was too lazy to speak to Wang Xuan in a nice way.
Lu Jinghua was sure that as long as Xu Cang dared to tell the vice president of maintenance about D Inspector's idea, Xu Cang would not be able to stay in this company.
Wang Xuan spread his hands, not caring about Lu Jinghua's anger, and left the office leisurely.
Lu Jinghua suppressed his anger and said to Xu Cang in a gentle voice: "Xu Cang, you are not a big shot, you are just a small second officer. This is not your responsibility. Just pretend that nothing happened, okay? If you have a psychological trauma about the 1566 plane, I will ask the planning office not to assign you any tasks for this plane in the future. Xu Cang, everyone should do their job, can't you just be an ostrich?"
"Then let's just let this matter pass and pretend it never happened?" Xu Cang laughed weakly: "But what if it happens again and they can't change it?"
Lu Jinghua also became anxious: "Isn't it more likely that it won't happen? Xu Cang, this is none of your business, so just stay out of it."
"Yes, I can avoid that plane forever, but what about the other crew members and other passengers?" Xu Cang shook his head, with an unprecedented firm light in his eyes: "I can't rest easy if this matter is not clear."
