Chapter 1063: Seven Days to Arrive

In fact, when Chang Haonan finished the first half of his sentence, everyone present had been basically convinced.

After all, those who could become leaders of the Aviation Power Group in the early 21st century, except for very few special cases, must have experienced various cooperative projects in the so-called "honeymoon period" of the 1980s.

So the nature of Western countries is more or less understood.

If the cause of the accident cannot be found as soon as possible, then even if Rolls-Royce does not take the initiative to add fuel to the fire, public opinion will eventually put the blame on China.

And the reason is not easy to refute-

As a model derived from a mature product, the Trent 900 has been calm and has no twists and turns for more than three years since the project was launched in 1999. As a result, less than half a year after China participated, one suddenly exploded without any signs, and the explosion happened to be the turbine part that you were responsible for producing.

Who would believe you if you said it had nothing to do with you?

What's more, Rolls-Royce is a British company, and it is hard to guarantee that it will not act as a troublemaker to shirk its own responsibilities.

Therefore, the only way to prove his innocence is to join the investigation as Chang Haonan said.

This way, at least he can take some initiative.

But before everyone can express their opinions, the second half of his sentence is confusing to everyone...

Especially Zhu Linyu.

He almost subconsciously adjusted his sitting posture, leaning forward slightly towards Chang Haonan:

"80% sure?"

In fact, in most cases, the saying "X0% sure" is just a casual and empty statement.

As long as it is not 100%, it cannot be taken seriously.

However, Chang Haonan had a glorious history of identifying the problem of M88 remotely before, so Zhu Linyu really ignored all the above questions:

"Can you explain it in detail?"

"Hmm..."

In fact, Chang Haonan himself was already quite sure in his heart, but he did not say it out of modesty.

But his judgment was based on his experience in his previous life.

Now he suddenly wants to explain it, and he really needs to organize his words.

After thinking for a few seconds, Chang Haonan continued:

"Actually, there is nothing special. Mr. Lin, who is in charge of business, should know that I asked Gaofa Group to remind Rolls-Royce at the end of last year that the turbine of Trent 900 has a design defect. After the turbine shaft breaks, it is easy to cause overspeed due to sudden loss of load."

He said and tapped the meeting report on the table lightly:

"Although Rolls-Royce's description of this accident is somewhat ambiguous, considering that the other party asked us to provide low-pressure turbine blades as soon as possible for accident recovery, it can be confirmed that this is the problem."

"But as I just said, the premise of causing overspeed and then causing the turbine blades to be thrown out is the turbine shaft breaking, and such an outrageous problem as the broken shaft is most likely caused by external force on the Trent 900, a relatively mature model. Combined with the abnormal temperature signal sent back by the sensor at the end, the inspection scope can be directly narrowed to the accessory system outside the casing, or more precisely, the fuel pipeline..."

"..."

In fact, Chang Haonan can be more precise.

The root cause of the QF32 accident in the previous life was that a short lubricating oil pipe installed on the bearing casing of the medium and high pressure turbine was not processed properly.

Under the harsh external conditions and frequent start-stop processes, this short pipe eventually broke, and the leaked lubricating oil caused a fire, which eventually caused the turbine shaft to lose strength and break.

Afterwards, Rolls-Royce inspected another 53 Trent 900 engines and found that the short lubricating oil pipes of 11 of them did not meet the requirements like the one that had the accident, and the other 42 could not find the processing and inspection records.

In other words, this problem is not an isolated case, but it was caught up by the unlucky Qantas.

And now on this timeline, except that the supplier of high and low pressure turbines has been changed to Huaxia, other parts have not changed.

It is normal to be induced in advance during the test.

To some extent, it can even be said to be a good thing-

It is better to explode on the test bench than in the sky.

Of course, he can only recall these contents in his mind.

It can still be regarded as reasoning to define a scope of investigation.

But directly pointing out which part number the problem lies in is a bit of a trick.

Even now, the effect is already quite obvious.

Lin Zuoming, who was a little hesitant just now, made a 180-degree turn and immediately expressed his agreement.

He even asked to personally lead the investigation team.

But in the end, he was rejected by Zhu Linyu.

First, it is now at a critical stage of the reorganization of the Science and Technology Commission. As the actual second-in-command of the Aviation Power Group and the most likely successor to the first-in-command, it is not suitable for him to go abroad casually.

Secondly...

Although Lin Zuoming is in charge of technical work, he only knows a little more than the other deputy general managers who are not from a technical background.

In essence, he has not been responsible for specific research and development work for more than ten or twenty years.

If he really leads the investigation team, he will be an outsider commanding an insider.

Of course, this second reason is more euphemistic.

But it still made the conference room full of joy...

In the end, it was Chang Haonan who ended the matter:

"Boss Lin, in fact, only one person can lead this investigation team."

"Who?"

Lin Zuoming was obviously still regretting that he had lost an opportunity to show off.

"Ren Bingda, the deputy general manager of Haofa Group, is also the person in charge of the Chinese side of Xiluo Group."

Chang Haonan replied:

"The high and low pressure turbines of the Trent 900 are officially produced by the Silo Group. Haofa only accepts subcontracting and is responsible for the OEM. So in any case, Rolls-Royce will not agree to the fact that we people are responsible for the production." Participate in the investigation.”

"Only Comrade Ren Bingda, by virtue of his position in the Ciro Group, is not so sensitive to the British, so he will have a certain amount of room for maneuver..."

…

After a whole night of discussion and planning, the group headquarters finally sent a rough action plan and requirements to Haofa Group before going to work the next day.

Zhang Zhenhua and Ren Bingda also conveyed Chang Haonan's request to Tim Purdy.

The latter's initial reaction was probably almost the same as Chang Haonan's.

"This is impossible!"

Bodi showed an expression as if he had eaten a fly:

"At the contractual level, there is no direct relationship between your group and Rolls-Royce. If a Chinese face appears in the accident investigation team, we will simply not be able to explain it to the board of directors."

Although it was he who suggested to Panos Watson that he could disclose the general circumstances of the accident to China in order to urge the latter to deliver the next batch of turbine blades as soon as possible.

But the proposal definitely does not include involving the other party in the investigation.

"But Mr. Purdy."

Ren Bingda had a brilliant idea in his hand, so he was naturally unfazed by this. He just smiled and pointed out the loopholes in the opponent's logic:

"As you said yesterday, if the investigation does not produce results for a long time, then our participation in the production of Trent 900 as an OEM will be made public sooner or later, right?"

"Although this may indeed cause damage to our reputation, if it really comes down to it, I'm afraid it will be your group...or Mr. Bodi, your personal losses will be more serious, right?"

Bodie immediately froze on the spot.

The previous sentence was exactly the reason he gave yesterday when he persuaded Zhang Zhenhua to jump in line to arrange production.

As a result, after one night, it turned into a boomerang stuck in my back.

Moreover, what Ren Bingda said was exactly what he was most worried about.

Subcontracting at various levels during the production process is a big or small matter.

If everything goes well, everyone is happy.

But if he really wants to go online, he, the deputy director, is undoubtedly the most likely position to be pulled out of the job.

But then again.

If a Chinese person participates in the investigation, even if the results are found, he may still take the blame...

Just as heaven and man were fighting in Bodi's mind, Ren Bingda calmly turned the notebook in front of him to the next page:

"Actually, Mr. Bodi, the size of our delegation does not need to be large. It only needs three to five people. Moreover, the members are headed by me, and they are all staff of the Siro Group..."

The meaning of this sentence is obvious.

It just means that there will definitely be no loopholes in the procedure, eliminating the worry of Bodi being settled.

However, the latter’s suspicions are still not so easily cleared away:

"Three to five people?"

For an accident investigation team, even with limited participation, this scale is really too small.

"Uh...that's right."

In fact, Ren Bingda was a little confused about this number, but Mr. Chang emphasized repeatedly in the morning that scale is not important, as long as someone passes by it, it will be considered a success, so he quickly nodded firmly and explained:

"In fact, we also considered that the accident involved a product we produced. We must personally rule out the possibility of defects in the turbine blades before we can be considered responsible for the product for life. That's why our superiors asked us to be a witness, so it doesn't take too long. On a large scale, it will not interfere with your normal investigation work..."

"And only in this way will we have sufficient reason to suspend the current production tasks..."

"..."

Verbally, you can naturally say a lot.

Anyway, as long as they can successfully intervene in the investigation, Luo Luo will not have the final say on what happens next.

What's more, Ren Bingda's promise was only not to "interfere" with the investigation.

I didn’t say it wouldn’t affect——

If I give you the investigation results directly, it won’t be considered an interference, right?

In short, after some verbal attacks, Bodi, who had already loosened his attitude, finally completely declined. He promised to report China's requirements and wait for the final decision of the project manager, but there was no guarantee that he would be approved.

Although they say so, everyone knows that the so-called "waiting for superiors' decision" is just an excuse used as a buffer.

However, for the sake of safety, Zhang Zhenhua, who had been silent before, still added a one-hit kill:

"Mr. Purdy, I hope you can give feedback to your superiors. Our investigation team will personally bring the turbine blades you ordered to the UK. The fastest... it will be in place in about seven days."
