Jovan Sommel: 巴黎航展在波音787坠毁的阴影下开幕,这起事故无疑给整个行业带来了沉重的打击。我们原本期待一个充满希望的航展,但现在焦点不得不转向事故的原因和影响。这不仅影响了波音公司,也让整个航空业都感到不安。 Guy Norris: 坠机事故导致波音公司高层缺席航展,活动延后。调查方向主要集中在飞机失动力和冲压空气涡轮(RAT)的启动上。行业内对事故原因的猜测很多,但关键在于找到确凿的证据。我个人认为,RAT的启动是一个重要的线索,可能指向发动机故障或电力系统问题。我们必须尽快查明真相,以消除公众的疑虑。 Jens Flothau: 这起事故对正处于转型关键期的印度航空来说,无疑是一场悲剧。他们原本计划通过引进新飞机和改善服务来重振旗鼓,但现在不得不面对这场突如其来的危机。此外,航空业还面临着关税争端等地缘政治挑战,这些因素都可能影响航空公司的订单决策。我担心这次事故会给印度航空的复兴之路带来更大的阻碍。

Welcome to this special edition of Aviation Week's Check 6 podcast, coming to you from Paris, France, on the eve of the Paris Air Show. I'm Jovan Sommel, Aviation Week's Editorial Director, and I'm joined by Guy Norris, our Senior Propulsion Editor, and Jens Flothau, our Executive Editor for Commercial Aviation. Guy, um...

The crash of a Boeing 787, not to mention the new Israeli-Iranian conflict has just cast a shadow over this air show as it's about to open. What are we hearing about the 787 crash? What are people saying?

You're absolutely right, Joe. Obviously, the crash has cast a huge shadow over the start of the Paris Airshow. And in fact, it's already led Kelly Ortberg, the CEO, and Stephanie Pope, the president of Boeing Commercial Aeroplanes, aren't here. And of course, all of the events that were scheduled have been pushed back because of that. So what are we hearing on the accident itself?

So the one thing that really strikes me is that there's a certain number of things which the investigators have got to be looking at.

Remember, we don't know for a fact any of these details from a sort of regulatory or investigation perspective. But just judging by what we're hearing from the overall community, the industry is obviously going to be looking at what they're seeing from the evidence of the videos and from the flight data and cockpit voice recorders, both of which have been recovered by now. But one thing that we do know is that the aircraft looks...

looked as if it lost power during that climb out, evidently in the few seconds before the accident occurred. And the other thing that we do know almost certainly by now is that the Ram Air turbine deployed in those literally few seconds of flight

The Ram Air Turbine, for those that don't know, is a sort of a two-bladed, small, drop-down propeller-driven generator, which essentially deploys out of the root, below the root of the starboard wing, into the slipstream. And it generates an emergency source of electrical and hydraulic power, basically for the primary flight control system. And

So that's a smoking gun, really, which the investigators would be bad to be looking at. Well, let's follow on with that thought, because it's not in the video, right? You can just hear it in the video. You can't see it.

Yeah, that's a really good point. So the sound is the giveaway. If you listen to the first few seconds of the video of the aircraft going away from the camera, there is this distinct sound of something, a turbine, which I think is a giveaway. You can't really hear much of an engine sound either, which also is, you know, very suspicious. Of course, 787-

has very quiet engines, it's a remarkably safe aeroplane. This is the first ever hull loss, of course, since it entered service in 2011. So it's a really big mystery. So this is something which we know investigators are looking at as a potential indicator of what happened. Just to quickly go over why the RAT would drop down and deploy, there's a number of reasons.

One is dual engine failure. This is something which would, unless it was a bird strike or something like fuel contamination, something so difficult to imagine happening, especially in those first few seconds of flight. Loss of electrical power to all instruments, the flight instruments. The failure of four electric motor pumps. Now these are the main, sort of like the heart of the electrical system on the aircraft.

to, I believe, related to each engine. If they fail on takeoff landing, that would trigger the drop down of the Ram Air turbine. And of course, this is designed to operate at all operational speeds and altitudes, supplying not only that power to the central electrical system, but also keeping a 5,000 pounds per square inch pressure to the aircraft's central hydraulic system.

And the other clue I think is that the landing gear, remember it was down and deployed during that whole sequence, we didn't see it start to retract. If the Ram Air Turbine deploys, it's actually prevented from raising because it's drawing hydraulic flow from the R80 itself by a check valve.

I don't know. I think that's got to be one of the key areas where investigators are looking. Jens, of course, you've been following Air India itself for a long time. What do you make of all this? You have to keep in mind this all happened two weeks after the global airline industry met in Delhi for the IATA annual assembly.

And it hits Air India at a crucial time in its history when it has started its corporate turnaround. I mean, if you're looking back, the airline's been in state ownership, government ownership for decades. It's been really, really in decline. It had dozens of aircraft on the ground because, you know, spares couldn't be paid. Aircraft were being cannibalized and everything. And three years ago, the airline got sold.

New management came in, Kemper Wilson, the current CEO from New Zealand, started his turnaround plan of the airline and they've made good progress.

bought a lot of aircraft, trying to refurbish cabins, reinstating and growing into international. So this is the context for them. And of course, it's a tragedy for any airline. For Air India, it hits the carrier when it was about to become a much stronger force in international aviation.

Guy, it seemed like Boeing was going into this air show with the wind at its back for the first time in a long time. You, Sean Broderick, and I were out in Seattle recently, interviewed Kelly Orberg, put him on the cover of Aviation Week magazine. Just awful, awful timing for them. What are people saying about the ramifications? If this is truly an issue with the aircraft itself or perhaps something caused by some sort of maintenance?

That's a great point, Joe. I mean, you're right. When we did come here, we were expecting a pretty upbeat message, actually, out of Boeing. 777X is well on its way, finally, to certification. 737 MAX-7 and 10, the final members of the family, similarly looking towards certification by the year end. So there was no doubt about it. Boeing had its tail up. It was coming into this show with, as you say, a good tailwind,

And you're absolutely right. I think the industry is sort of holding its breath at this point because if there is an issue which is obviously aircraft system related, that's going to be a big deal because, you know, this aircraft is in widespread service. It's the backbone for many of the international carriers on super long range routes and aircraft

It's a main sort of fundamental element of the current air transport system. And it's also absolutely key to Boeing's future throughout the next decade. It needs this airplane like no other at the moment to maintain cash flow and it's got big plans to continue to increase production. So I think the industry is on a knife edge right now with this because it really needs to know pretty quickly what has happened.

And don't forget the broader context here. We're meeting here with the tariff dispute ongoing, the 10% tariffs that are in place right now that could go up to 50% within a month. And if any of that happens or stays,

the global globalized aerospace industry as we've known it for decades will be gone. I mean, it is as serious as that because a lot of the structures will not be able to will not be maintained. So it is a very

It was going to be a very, very different airshow from the previous ones. Even without that tragedy of Air India 171, that just makes it so much worse. So we've got Air India, we've got the tariff situation. And what I'm observing going into the show

on the commercial side is that geopolitics and politics in general are playing a much, much bigger role now. So obviously we won't see any boiling waters here of any relevance because of the Air India situation. I get that. But in general, orders are going to be much more affected, influenced by the political situation.

Trump going to Qatar, Qatar Airways orders 160 Boeing's. There's a big campaign at LOT Polish Airlines between Airbus and Embraer. Normally you would say that's one that Embraer should win because they have an incumbent Embraer fleet there. But nowadays can Poland really go for Embraer when at the same time everyone talks about strengthening the local, in this case the European industry?

There's this big China order looming that everyone's been expecting for a while. But as the US-China trade conflict continues, can China really go with a Mabos order to make Trump even more mad than he's already? So this is the context now. So very unusual air show for structural reasons and obviously with very sad news at the beginning.

And Guy, you're supposed to be out today. You're supposed to be at briefings for CFM and you're supposed to be at a briefing with Kelly Orpberg. As I said at the beginning, this crash investigation really has cast a cloud over this air show, hasn't it?

Yeah, very sadly. Yeah, the whole of the original plan has been scrapped, I guess, for obvious reasons. And I think the rest of this show, certainly from a commercial aviation perspective, is really going to follow a lot of the trends that Jens identified. Plus, of course, people being on the lookout to see, you know, where the investigation is going in terms of the Air India accident.

It will be interesting to see whether it's driving towards a technical answer, some sort of failure within the system itself, or whether it's much more to do with either a maintenance or an event incident to do with operations. We just don't know at this point. Okay. Well, I mentioned at the beginning we also have a war going on now or a conflict.

It's crazy. We put the air show issue of Aviation Week magazine to bed Wednesday night and I went home and said, "Okay, we can just coast into the air show." We had an air crash and then we had this

conflict begin. Robert Wall on our defense team will be recording a Check 6 podcast in the next couple of days where they'll talk much more about the conflict in Israel and Iran and what people here are saying. And then Jens and Guy and I will all be back with you later this week for another Check 6 to talk about the commercial highlights from your show.

But for now, that is a wrap for this Check 6. A special thanks to our podcast editor, who is here with us on site, Guy Ferneyholt. We will see you later in the week.
