Second Qantas jet suffers engine problems

A second Qantas airliner suffers engine problems and makes an emergency landing, again at Singapore.

Coincidence? It must be.

A 747 of theirs had an engine cooked as it was preparing to depart Sydney to LA.

Re: Second Qantas jet suffers engine problems

I supply a lot of parts to the aerospace industry, and I can tell you these are NOT coincidences. Given the degree of reliability and control thus industry demands, these critical failures should be less than one-in-a-million.

Qantas clearly has an issue. So far, no one has been hurt, which is great - but they are doing something wrong.

Okay, let me back up a sec: every airline does something wrong. Qantas is probably doing that critical, tiny number too many.

Re: Second Qantas jet suffers engine problems

In the past, we've heard of issues relating to having their maintenance done abroad eg in Singapore, Malaysia and so on ( basically an issue of out-sourcing ).


http://www.news.com.au/travel/news/p...-1111117021099

Could outsourcing to lesser developed countries have contributed to these incidents or is there something else wrong with Qantas ?

Re: Second Qantas jet suffers engine problems

I'd really hate to say. Jets are big, complicated things with mountains of strictly controlled procedures that are the product of years of experience. The problem could be a subsupplier, contract labor, warehouse conditions...a lot of things.

What you're suggesting is not unreasonable, but without knowing I wouldn't hazard a guess. I'm just saying my gut tells me there's a problem. If you detect one failure, there's more. They are having several critical failure in a bunch - once-in-a-lifetime, possibly never-in-a-lifetime failures cropping up together. This shouldn't be happening.

I also guarantee that the people at Qantas, although they talk a calm game, are having the shit-fits right now as they try to sort this out.

Re: Second Qantas jet suffers engine problems

Blame the accountants ... and this is not a surprise, the Qantas maintenance staff recognised this years ago: http://www.amwu.org.au/read-article/...nce-standards/

Quote:
Qantas workers concerned over maintenance standards
Sep 10, 2008

Off-shoring, contracting out and cost-cutting by QANTAS is impacting on maintenance standards according to a new poll of Qantas maintenance workers.

...

When asked about the effects of contracting out, outsourcing or off-shoring:

• 69% agreed work needed to be re-checked more often
• 67% agreed work has to be re-done before it meets standards
• 62% agreed QANTAS has a cheaper service but corners are getting cut

Re: Second Qantas jet suffers engine problems

A few people I work have have contacts in various bits of Qantas and reckon it's partly the outsourcing and partly the constant full throttle used on long-haul flights ragging the engines out in short order.

Re: Second Qantas jet suffers engine problems

... Colonel, with all due respect, I think an airliner in cruise flight is not quite flying at full throttle ... actually a whole lot less than that.

I'd venture a guess that many short-haul flights in a day put more stress on a turbine engine than a nice long-haul flight (minus volcanic ash).

What he said ... costs the airline more money to run at full throttle than a moderate cruising speed, too, as the fuel burns faster, which means they need to load more fuel, which means they have to burn more fuel to carry that extra fuel ...

Re: Second Qantas jet suffers engine problems

It seems though, that there have been some issues in the past as well.

Re: Second Qantas jet suffers engine problems

This reminds me of ( later proven true ) Malaysian airlines, amongst others, who flew on dangerously low fuel on long haul flights to cut corners.

I'm surprised Qantas has not made an effort to legally own and thwart that domain.

Looked into it a bit more and it's the LAX to Sydney and Melbourne routes where they really rag the engines. From what they said, they have to fly at a significant fraction of full power for that route, quite a bit more than the overland routes.

As an aside, did you ever get that F-14 drawing?

Re: Second Qantas jet suffers engine problems

These are just coincidences. The A380 engine failure was proven to be a manufacturing/design problem within the engine, nothing to do with Qantas.
They still have the/one of the best safety records, and are trying to keep it. They were the first to ground all their A380s, and still haven't got them all back in service, partly because of this:

They are not flying that route as it requires full thrust for take-off, I assume because of the fuel load/weight of the aircraft required. I believe that's their decision, not a directive from a manufacturer.

And outsourcing isn't proven to be a problem. Of course the Qantas staff will say that. They lose their jobs if it's outsourced.

QF31 had its engine forcibly shut down.

Well. If you're going for an oil change, Dubai's the place to do it.

Re: Second Qantas jet suffers engine problems

Emirates A380 engine blow out in Sydney whilst ascending. The staff panicked more than the passengers.

Passengers on board an Emirates A380 flight from Sydney say they saw a bright orange flash and felt the plane shake in a mid-air scare less than an hour after take-off.

The problem, believed to have been caused by one of the plane's engines, occurred on Flight EK413 bound for Dubai which departed Sydney at 9:45pm on Sunday night.

Re: Second Qantas jet suffers engine problems

sounds like a stall/surge and the panic from the tea / coffee servers sounds about right.
