On Wednesday, Air Greenland sent an AS350, and the pilots managed to find a number of parts from the aircraft. However, the remaining parts still need to be found, and it is currently difficult for weather conditions in the area.
Looks like the light weight, high drag parts in the trajectory field. I wonder how good a metal detector probe might be to pick up a hundred pounds of metal embedded in the Kevlar shroud blanket.
With all the drifting snow, you would need an army of men with metal detectors to find most of the bits. If it was not a Bird-Strike, or a Drone, then maybe even a Meteorite-Strike is possible.
Although there is no signs of damage to the drive-shaft, the GP7200 has a 4:1 gearbox, ( and the GP8000 has a 3:1 ratio gearbox.) which could have played some part in the break up.

No not the accessory gearbox, from what I have read, there is an (epicyclic?) gearbox between the turbine and the fan in these GP engines. Also there are different sizes of fan 116 and 118 inches depending upon model, mentioned in various publications.

At someone who puts too much fiction in his science and someone asking for speculation which has occured enough on all the pages of this thread.
Or did you ask something specific with that question and i just don't understand you?
oh wow that helicopter image really makes it hard to find the reply button lol (scroll to the right :P)

is the pope catholic? 
seriously no idea - but i guess AB BEA PW/GE AF TSB and maybe NTSB are crawling all over it

As a former aircraft engine designer I think it will turn out to be good old fashioned fatigue. I have compared this P&W/GE engine with the R-R equivalent and I would guess a three shaft solution is a better design. I worked on the Conway when I was a lad - the first two shaft engine I think.
Surprised we haven't heard anything from passengers about how long they were stuck on aircraft. Maybe just glad to be alive or maybe a cultural thing. How long were they there exactly?

We did hear from a passenger:
The second link has fewer ads, but the first link is written up better.
Here are my pics, videos and what not. It's been a long day, glad to be alive though. https://nonbiasedreviews.com/air-fra...ngine-blew-up/

AvHerald says the accident aircraft landed at 15:41Z; passengers were kept on board of the aircraft until arrival of the replacement aircraft because the airport does not have stairs to accomodate the A380; AF's 777 arrived to pick them up at 05:50Z and departed at 09:55Z (and a 737 for the rest of the pax somewhat later).
Incident: France A388 over Greenland on Sep 30th 2017, fan and engine inlet separated
If that's accurate, pax were on board the A380 at Goose for between 14 and 18 hours. No explanation of how they got off the A380 if the airport doesn't have stairs for it; I suppose the airport improvised something. Anyway, as others commented up-thread, (a) the airport probably couldn't accommodate over 500 pax and crew; (b) if they'd got off, rules (aka bureaucracy) might have required them to be processed by Canada immigration, which would have taken forever.
I haven't seen any complaints from pax, so I guess they were kept comfortable enough, and if they'd seen the engine, glad to be on the ground.
I suppose the airport was able to provide ground power and/or refuel the APU - or would there have been enough fuel on board to run the APU for that long? And ... I wonder if the airport was able to provide food and water .. and if they were able to clean the toilets during the wait ...

Maybe Airbus and airlines operating the A380 should chip in a few $ and equip a few of these remote Canadian airports with airstairs capable of handling it.

What happens to hold baggage?
Question: after a diversion to a remote field without facilities, such as this one, or the Swiss 777 at Iqaluit earlier this year, what happens to hold baggage? Is it always transferred to the aircraft that evacuates the pax, or does it sometimes wait until the airline flies in baggage-shifting equipment, or even until the failed aircraft is repaired and flown out? If the latter, that's quite an incentive to carry on as much as you can ...
