Qantas A380 engine 'explosion'

this same aircraft also had an emergancy landing at LHR in June beacuse of a failure of it's nose gear steering.

To underline what an excellent job the flight deck crew did here I believe they landed it with:
- out of service #2 engine
- resulting in no reverse thrust on left side as the outboard engines on the A380 don't have reversers
- a hole in the wing which has clearly vented an (as yet) unknown fluid, likely to be hydraulic
- #1 engine is believed to have been stuck at cruise thrust due to lost communication with the flight management computer caused by shrapnel from #2 engine failure. (Evidence for this is firefighters having to 'drown' the engine after landing.)
- loss of hydraulics means not all spoilers deployed on landing, again increasing roll-out length.
- wet runway.
- near to max landing weight.

I think I've just watched too much air crash investigation ii)

Agree 100% Clarkey- really a remarkable bit of landing.

An old school friend is a QF 744 pilot and am trying to get the inside story of him. If says anything of interest I will be sure to let you guys know.

It's not Qantas' week as another QF A/C, a 744 has also gone tech today, returning to SIN with engine problems.

I wonder if it's fitted with the RB211-524G/HT engines - they have the same core as the RB211 Trent 900 on the A380.

QF will be treating any engine problem with a great deal of caution at the moment so the slightest concern - back you go!

You clearly are a glutton for punishment, a fear of flying but works in aviation and watches air crash investigation!

With the amount of rotations budget airlines put on their planes, the distance long haul 'craft are doing it's utterly shocking and a credit to the industry that accidents/incidents are still newsworthy!

In the BBC News article, one passenger on the 747 said that the Captain told passengers to go into the brace position. Whether this was more serious at the time than the A380 incident the day before or the staff were not taking any chances after yesterday I don't know, but it is certainly a bad week for Qantas!

Wonder if they will stop all their 747s now for the same checks as the A380s? But then they'll be in serious trouble with the fleet!

It seems Qantas have started a new route.... SIN-SIN. I wonder if it's available to book via Opodo.....

One tiny part with a misaligned counter-bore.

So many parts and so many steps in manufacture and it takes two drills being slightly misaligned to nearly bring down an aircraft.

Great find, thank you!

At least it is being reported as a "manufacturing" defect rather than the much more serious "design" defect.

Prelim. report now out.

A busy time on the Flight Deck!

Nearly bring down an airliner is over stepping it a bit, certainly there was a little excitement on the flight deck for a couple of minutes, but in reality there have been far worse uncontained engine failures that have done far more damage and the airliner landed without any issues.

If you want to see what a real uncontained failure is do a search for UA 232, only due to the outstanding skill on the flight deck did anyone walk away from that one.

Sorry, I was thinking that if all the parts had been machined wrong in all 4 engines and failed at around the same time.

Do airlines switch engines around so that they have some newer and some older engines so if there is a problem they wouldn't all fail at the same time?

Most, most unlikely to have two engine failures at the same time unless they result from some external issue common to more than one engine.
This is the basis of ETOPS.

I must admit though, in the back of my mind, I still do have a preference for 4 engines for long haul.

[Scrooge]

Certainly a 340/747/380 will perform a lot better than say a 777/330 in a two engine out situation

With that said, as Bill said, unless there is an outside force acting on the engines (bad fuel, multiple bird strike) losing two engines at the same time is very rare, I guess if there is a design or manufacturing issue it could happen.

I guess if there is a design or manufacturing issue it could happen.

I guess that the damage to the systems that meant they could not shut down the #1 engine until they flooded it on the ground, could easily have done damage that took it out of action

Bloody hell!
All 3 engines go on an old Tupolev..

Suggests fuel....

There is a major problem with aviation fuel being transferred to black market heating fuel in Moscow.
Not sure what comes back!

Good interview with the check-captain...
