While Wang Bin was chatting with Master Qiu, the professor and the others had already stepped forward to check the condition of the engine.

Although according to previous inspections by Teacher Qiu and the others and the manufacturer, the engine was not the cause of the extra points, but Wang Bin and the others had to check it themselves before they could rest assured.

At the same time, they also want to see how the engine is damaged after such a major accident, and if possible, they will also make improvements to this engine specifically for such accidents, making it , In the future, this is what happens when you encounter such a thing, and the engine can also maintain a certain power.

For example, with intelligent design, if the engine fails to restart many times, the engine will automatically switch to the electric drive mode. In this case, such accidents can be effectively avoided.

At the same time, they also want to know what is wrong with the plane, whether it is a problem with the parts of the fuel system, or a design defect in the process of improving the design of the plane.

After chatting with Master Qiu for a while, Wang Bin also stepped forward to find the cause of the accident together with Professor Chiu and others.

In fact, due to the crash of the plane, the entire plane has fallen into disrepair at this time, the fuselage has been segmented into several sections, the main wing has been completely broken, and at the same time, the entire nose has disappeared. When it crashed, the nose of the plane hit the ground first, then the fuselage.

Fortunately, the place where the engine is installed on the fuselage has been strengthened and improved, so it is better to maintain a relatively intact state. This zero-inspection work is relatively much easier. Otherwise, if the aircraft is completely damaged, if you want to find out the problem, just Difficult.

After Wang Bin and others came to the wreckage of the plane, they first found out the engine data recorder in the plane's engine with Professor Zha and others. After all, since this engine is a new type of engine, Tiangong Technology For better data collection and future improvements, this engine is equipped with a data recorder.

Subsequently, Wang Bin, Professor Zha and others found out the data recorders in the two engines, and immediately used the equipment to check their data.

Of course, when Wang Bin was checking the data of the engine, Master Qiu and the military personnel all saw Wang Bin's movements and gathered around to check the data with Wang Bin and others.

After all, they didn't know before that there was an independent data recorder on this engine.

According to the data, just before the aircraft engine stopped, the fuel supply of the engine had fluctuated many times, and the oil pressure of the oil supply pipeline to the engine had also changed many times, and finally the oil pressure dropped sharply until the fuel supply was cut off. .

Seeing these data, Wang Bin said: "Master Qiu! You see, there was a problem with the fuel system before the engine stopped, and it didn't take long for the problem to deteriorate rapidly before the plane landed, causing the engine fuel system to fail. If the supply is disconnected, the engine will stop without fuel supply."

After seeing the data records on the engine, Qiu Shi also nodded and said: "It turned out to be this problem, that is to say, the cause of the accident of the plane should be a problem with the oil pipeline or the oil pump, but it is no wonder that we Multiple re-ignitions have failed."

And Wang Bin nodded and said: "The possibility is very high, but it may also be caused by the oil circuit screw or the connector falling off."

Thanks to the data on Wang Bin's Tiangong technology engine, it is much easier for everyone to find the cause of the crash, so everyone immediately began to search for the oil circuit system of the wreckage of the plane.

And soon, someone made a discovery.

"Everyone, come and have a look, I'm very likely to find the cause of the accident."

Following the shout of the staff member, Wang Bin also poked the professor and waited, and immediately walked up, came to the staff member and looked at it.

It turned out that the place where the staff member was located was an oil pipeline connection of the plane. However, at this time, many parts of the oil pipeline near this interface had been burned during the crash, but judging from the surrounding wreckage Come on, there are obvious oil stains in good places.

At this time, someone found a strange place on the side, that is, they found a cracked screw near the oil pump not far away, and according to his analysis, this screw was not caused by the crash of the plane. During the process, it fell apart. The most important thing is that this screw is exactly the screw that used to firmly fix the oil pump and the oil pipeline.

After checking here, everyone at the scene has already targeted, and they have found the main reason for the accident.

In other words, the accident was actually caused by a small crack on such a screw.

Because the purpose of this screw is to fix the oil pipeline and the oil pump, and the breakage of this screw caused the screw to loosen and eventually detach, which directly caused the main oil pipe to fall off, causing the plane to crash.

When the result came out, everyone stared blankly at the screw with obvious cracks, and everyone felt an indescribable feeling in their hearts.

No one thought that the most important cause of the accident was actually caused by a small crack on this small screw.

After coming over for a while, Master Qiu directly said in a loud voice: "Immediately look up all the screws of the same type, which manufacturer produced this screw, and at the same time, I want to know how many important official companies we have are using this type of screw. "

It was obvious that Master Qiu was very angry at this time, but it was no wonder that even at this moment, Wang Bin was not angry in his heart.

Soon, the manufacturer of this aircraft inspected the same batch of screws of the same type and the same manufacturer. As expected by Wang Bin and the others, the quality of this batch of screws did not meet the requirements of aviation screws.

At the same time, they also found out the manufacturer of this screw. In Wang Bin's mind, he guessed that this must be a screw produced by an official company, but this is not the case. The batch of screws is not an official domestic company. What is produced is not produced by a private enterprise, but is produced by a joint venture.

When this structure came out, everyone felt even more uncomfortable, especially the personnel of the manufacturer who produced the improved No. 6 aircraft.

Because the suppliers of most of the parts in their factories are basically official companies, only some small parts and unimportant parts will be purchased from outsiders, and screws are one of them.

However, their factory also clearly stipulates that the procurement of components and the selection of processing companies must be domestic enterprises, and there is no enterprise with foreign capital participation.

But the situation is different from what they thought. It is obvious that there is a problem with the purchasing department of their factory, and it is still a serious problem, as well as the quality inspection department of their factory's purchased parts.
