Re: AF66 CDG-LAX (A388-F-HPJE) diverts to Goose Bay (YYR) with an uncontained engine failure to #4 engine

The investigators are lucky:

Some missing parts from #AF66, which lost an engine fan and inlet over Greenland, have been spotted on the ice sheet by helicopter and plans under way to recover them, BEA says

That is pretty quick to find, well done to the recovery team.

Thanks for catching that. I did a google search on GP7200 and did not check the results carefully enough.

It looks like the shaft is related to engine mechanical power transmission as stated earlier

Can't wait to see some pictures, that'd be very interesting to see how they broke up.

The seizure theory is one theory. Another theory is a materials failure ie microscopic deficiency leads to crack forming and then catastrophic failure.


Just to be clear, I don't think the seizure theory is the cause, I believe like others, that this could be a material failure that lead to a crack forming. But I am curious if the engine has infact seized or not, hence why I asked if the part that is sheared off should normally rotate or not.

Thanks for your replies though.

I have sat through loads of investigation presentations and normally it's not just one cause/reason engines fail like this. Now this could be one that's away from the norm and it's a single cause. It should be a quick investigation if that is the case. Especially if they get both halves of the disc that failed.
The investigators will already know if the engine still turns and will have ruled it in or out.
They may have already ruled in or out material fatigue failure. It's a very obvious failure mode if the crack has not been too damaged during the failure event.
What surprises me is, if they thought it was that, I would have expected immediate inspections either to be done voluntarily or if not be instructed.

I think we might just find it's a more complicated failure than just metal fatigue.

I am watching with great interest for the first news from the investigators.

If I was running AF maintence department, I would definitely be looking at the way to check suspicious spot on other engines. It may be an inconclusive inspection, and may be easier to say than actually do such a thing, but if at least something may be done....

Hope that is correct and that they find them all. The Sioux City Investigation only went into gear when the farmer found the engine parts. And this may be the really lucky part: The fact that this flight was west coast bound took it over Greenland. If this had been bound for JFK or other east coast airports, those parts would be in the drink because we almost never fly that far north (I do the JFK run a lot).

Of course there will be; but inspecting other engines for signs of similar failure has to be part of it regardless. After all, discussion must be based on some data - and if data says engines got some problems...

But was it a complete coincidence? If the engine failed when thrust was increased to climb to a higher level, it could be very logical they did so over Greenland to meet an ATC restriction flying over the ocean to Canada?

More than likely there will be a mapping of what the parts are and in which order the hit the ground as that might help tell them what failed first. If so, there may be a wait until these are pulled out of there.

Yes, looking at the map that is the edge, I am wondering "how far east, how far south" as the pictures look like it is on the larger ice sheet.

Yes, twin losing an engine would be a blood pressure booster. That is why I seek out the 4 holers for trips over the drink. Odds are good on a twin, but I like the 4's a lot better, period.

Well 4 holers aren't going to be around much longer, soon your only choice is going to be an A380 or LH748

They just got retrofitted and put Y+ into the market, plus the high&hot needs of IB destinations and delivery slots for the A359s and A330s, you can expect 5-7 years minimum flying.

Hollow titaniun blades, so one-piece. The GP7200 is built around a .72 scale GE90 110B/115B core, & PW fan & low pressure system.

Having had a second look, I have to disagree with myself.

Yes, it certainly appears to be a piece of fan blade. Cannot say if leading edge or trailing edge. You can see it's two pieces joined together so yes it's a piece of fan blade.

If this is a fan blade, than the airplane was A380 model airplane scaled 1:5.

Just compare the size of this metal part with the shoe of the photographer.

nobody said it was a complete fan blade, with price tag still attached. :-)

But was it a complete coincidence? If the engine failed when thrust was increased to climb to a higher level, it could be very logical they did so over Greenland to meet an ATC restriction flying over the ocean to Canada?


What ATC restriction? Airplanes, including Twins, fly over oceans all the time for Canadian destinations. Besides, the original destination was LAX.

The A380 was over Greenland as that routing is close to the great circle (shortest) path.

Oh, I had not recognised this as a shoe before reading your message. :-)
On the other hand, given what it went through (the fan case probably...), it could be just a fragment of a blade.

I looked a bit at the diagram and do not see what other part it could be. Any idea ?

If this is a not a fan, what is it?

I didn't think it was a piece of Fan blade until I looked at on my iPad instead of my phone.

I think it is a piece fan blade. What makes me think that is the shape of the radiused edge. Also I see that it is made from two pieces of titanium diffusion bonded together.

I did spend several years working on making Fan blades.

There not many parts diffusion bonded together on an engine so I am 99% sure.

I was thinking they would be talking to some ATC station in Greenland and swich to Gander ATC once over the ocean but it seems most crossings over Greenland are controlled procedurally from Reykjavik except for the very South which is controlled by Gander(?).
Thus if they did just start a climb this probably wouldn't have anything to do with Greenland and having to be at a certain flightlevel before joining Gander. The parts falling over land would be a lucky coincidence indeed... Just saying that in aviation what might seem a coincidence at first could be the result of the procedures followed.

It's not so much one engine going poeff. This happening on a twin, I would listen & watch the remaining engine as if my life depended on it. I would wonder why #1 failed, something obviously went wrong. Is that something relevant for #2? On a polar ETOPS 330 flight..

Yes, twin losing an engine would be a blood pressure booster. That is why I seek out the 4 holers for trips over the drink. Odds are good on a twin, but I like the 4's a lot better, period.


Well 4 holers aren't going to be around much longer, soon your only choice is going to be an A380 or LH748



Yep, them's what I fly when I can.

Are they going to longline those larger parts out underneath a helicopter?

there's a three day old article in danish describing a bit about the search (selected bits below, my translation):

https://knr.gl/da/nyheder/air-greenland ... dlandsisen

Det fortæller Martin Puggaard, chef for Havarikommissionen i Danmark.
- Vores opgave er at finde og bjærge de dele fra flyet, som har forladt flyet. De skal efterfølgende sendes til de franske myndigheder, som har det overordnede ansvar for undersøgelsen, siger han til KNR.
Onsdag lykkedes det personale fra Air Greenland at finde flere dele af motoren på Indlandsisen, 150 kilometer sydøst for Paamiut.
Umiddelbart kan det lyde som at lede efter en isklump i et isbjerg, men ved at analysere de tilgængelige fakta, er det lykkedes for Havarikommissionen at indsnævre området til i første omgang fem gange femten kilometer.
- Vi har lavet en analyse af flyets rute, højde og vindhastighed og på den baggrund har vi lokaliseret et område, hvor vi har ledt, siger Puggaard.
Onsdag sendte Air Greenland så en AS350 afsted, og det lykkedes piloterne at finde frem til en række dele fra flyet. Men der mangler stadig at blive fundet de resterende dele, og det er i øjeblikket besværliggjort af dårligt vejr i området.

Says Martin Puggaard, chief for the danish accident investigation board:
"Our task is to find an recover those parts which have departed the plane. They are subsequently to be sent to the french authorities, who have the primary responsibility for the investigation".
wednesday, personnel from Air Greenland succeded in finding several pieces of the engine on the inland icecap, 150 km southeast of Paamiut.
At first blush it might sound like finding a icecube in an iceberg, but by analyzing available data it has been possible to for the AIB to narrow the area to about five by fifteen km at first pass.
"We have made an analysis of the planes route, height and wind speed, and on that background we determined an area where we have searched", says Puggaard.
Wedesday Air Greenland sent a AS250, and the pilots succeeded in finding some parts of the plane. But there still remains to be found the rest , and at the moment the weather is hampering the search.

Amazing...they can find a 1m long piece of a fan blade which exited a cruising aircraft at 38,000ft and landed on an Arctic shelf of ice, but we still cannot locate a missing airliner on the other side of the planet.
None shall pass!!!!

It would have been very easy to find that missing airliner if it was on top of a white snow covered ice sheet....

They will not likely find any of the parts that impacted the water - or penetrated the ice and sank.

Have a great day,
