Any word on how long QF will keep their A380 fleet grounded? Scheduling nightmare?

I am very happy that this everyone was okay after this event. I shows that aviation engineers has built in some unique safety features. 40-50 years ago, this event could have been more dramatic.

I read in a Norwegian newspaper that SQ also have grounded their A380 airplanes, and LH wondering about the same thing. Anyone else got that info? Sorry if this was discussed in thread 1, but could not find any info about it.

Previously, Bralo20 (I think   ) posted about the ignition temperature of Jet-A1 being 38C, and that a spark from the debris could have caused a fire.

Firstly, I doubt there would be enough oxygen at the altitude this occurred to propagate a flame outside of the pressure hull.

Secondly, and crucially, the 'heat' part of his fire triangle is missing. The engine may have been on fire briefly, but compared to tens of tons of Jet-A1 at -20C or so it wouldn't stand much of a chance.

EK and AF are using the GP7200 engine instead of the RR Trent engine, so since it's an engine related happening there is no need to ground the planes with the EA engines. LH however can still decide to ground their planes if they think it's necessary or if they are asked to do so.

I'm not opposing the fact that Jet-A1 is hard to ignite, but... Debris fell down in the Batam area, that is reached within one or two minutes after take-off from SIN. The outside temperature is still warm, and the air preassure is not too far from sea level.

It depends indeed on the altitude, at the higher altitudes there is indeed lack of oxygene in the air but at what altitude happened this "event"?

It all depends on the size of a possible leak, the size of a possible fire and the altitude the event happens.

Anyway, nothing serious happened in this case and that is the most important

But the last line said "delayed", not "grounded" for SQ's A380 flights. By that I presume they are going to do sequential checks on each aircraft, thus causing some delays.

I am not sure if SQ has enough capacity to use other aircraft to address the shortfall if it is for an extended period. But for QF it should not be a major problem.

It's always interesting (and I mean this respectfully) to see engineers comment on failures such as this. I believe everything they say, nevertheless a spectacular failure like this will result in a lot of press coverage and doubt that RR is going to have to deal with. Not sure why many think this is an anti-Airbus issue, the plane seemed to perform in a spectacular fashion and saved a lot of lives even though damaged. Luck, maybe, but good design as well IMO.

I find it interesting that the focus of this thread so far is that of Airbus and Rolls Royce bashing, both of which are not common on this thread, with certain a-netters just as sensationalist as cheap tabloid papers:

So lets look at the possibilities:

- Engine design fault/build fault.
- Maintenance issues - Qantas has been slammed before for this so it should not be discounted (then again an open mind is required!).
- Bird Strike - The plane had afterall only just taken off from Singapore so that is a possibility.
- Possible effects from a number sectors in the vicinity of the volcano on Java.

The A380 is a very reliable aircraft but unfortunately gets slammed due to its profile. I'm sure all parties involved will do their best to get to the bottom of this but any undue criticism or seemly hateful remarks do not help matters at all.



Next Flights: LGW-SVG (738-DY), SVG-LHR (319-BA), LHR-HKG (388-BA), HKG-SYD (333-CX), SYD-HKG (333-CX), HKG-LHR (388-BA)

Delays to A380 flights


04 November 2010

Our engine manufacturer Rolls Royce and aircraft manufacturer Airbus have advised us to conduct precautionary technical checks on our A380 aircraft, following today's incident involving another operator’s A380.
Resulting from this development, Singapore Airlines will be delaying all flights operating our A380 aircraft.
We will keep affected customers updated and more information will be provided once it is available

I have read both threads and have read nothing but praise for Airbus and Qantas - the crew in particular. I am more of a Boeing fan, but am truly impressed with how well the 380 performed and don't recall any serious criticisms of the plane. RR is taking criticism because this is their second uncontained engine loss of a recently developed engine. That doesn't seem unreasonable.

Why do so many people get so defensive over such a thing? Rolls Royce somewhat deserves some questioning as they seem to have problems lately (uncontained engine failure on test stand, and now this.)

In my opinion, this could of been a lot worse.

Interesting ... according to passenger interview ( http://edition.cnn.com/video/#/video...qantas.engine.passenger.cnn?hpt=T1 around the 0:55 mark), he claimed that after landing, and having emergency crew work on the aircraft, there was still fuel leaking from engine #2, and engine #1 could NOT be shut down.

If true, I'd guess that there was more damage to that wing that one might have first thought.

Kind of surprising that they circled for more than an hour to dump fuel before landing. In a case where the fuselage has been physically damaged I would think that you would want to get the a/c on the ground ASAP.

With all due respect, would you mind clarifying your two statements?
1. Do you bet on a blocked vent, or was it a blocked vent?
2. Is it really true that this IPT disk cannot be maintained or even checked, how is this possible that a modern aircraft can have parts that cannot be checked?

There have been no uncontained 787 engine failure, a RR test engine failed during test runs in a lab.
