14 hours after landing??? Not a chance any airline could be that pathetic. I would have been one of those passengers gooing all my toys out the cot if they really did pull that stunt
Did you consider that there may actually be no where for 500 odd pax to go in Goose bay? staying on board may have been the only option.

Nope did not consider that but surely a runway/airport that can handle those aircraft should have some form of area for passengers to sit??

Emergency divert i guess. the whole place has only 8000 people and a search showed few hotels. also its only 6 deg there so would think Pax are poorly equiped to deal with that. :) logistics must be a nightmare

Hydraulic fluid is purple, engine oil is orange which is what we are seeing here.
When they use the loaded term "denier" that should be the first clue that we're not dealing with a rational opponent in a debate... but "religious" dogma.

Most aero hydraulic oil is red,however, fire resistant oils tend to be undyed, thus light straw color. (But then also, Aeroshell Fluid 61 come in dye and undye version.). Once under pressure most hydrailic oils change a bit in color. Mostly tend to turn darker.
One would think that a standard would be set to safeguard against wrong oils for wrong application.Not so,and manufacturers say that in the computer age it is cheaper to rather control via LABELS then dye.

At first I thought that they may have lost a cowling and it was much ado about nothing. But if you have a proper look at the engine you can easily see that half of it is missing!

The fan is gone! Big kak there!

You would think it would fail during takeoff not in cruise. How hard do engines run (% of available/possible thrust that the engine can produce ) during cruise.

According to Av Herald there were no stairs available for an A380 in Goose Bay. Wonder how they got them off in the end?

Thanks guys, I knew I could come to here to get more info after it hit the news.

The fan is completely gone! structural failure or foreign object ingress? time will tell I guess.

Are these fan blades the same tech as composite Ti / Carbon like in the RR equivalent?

As far as I know the airframe and wing are designed to deal with catastrophic engine failures such as this.

Average take off dependant on reduced thrust capablity = 91% to 94%
Average climb thrust = 85%-91%
Max continuous = approx 95%
Cruise = 80-85%

approximations of % of N1 RPM

these numbers are a good rule of thumb, if things like computers or EPR gauges go "belly up",

Unlikely since the first and business guys (upper deck) were first to depart.

I saw a tweet from one of the passengers that the reason for the passengers staying on-board is that the airport doesn't stairs that that can cater for aircraft of this size. Confirming what Glenn L wrote...

If you don't gear up your brain before takeoff, you'll probably gear up your airplane on landing.

The different fluids are clearly colour coded with Skydrol or Chevron Hyjet being purple, the old Mil-H-5606 is red (do they even use it anymore?) and the original vegetable oils are blue.
