Heres my 2 bob worth......
Sunfish,
Operating procedures would not really be an issue these days as the 524 and GE engines are controlled by an EEC or FAFC. Most of the failures (excluding bird strikes or FOD ingestion) originate from an internal failure in my experience.
There is the odd failure induced by defects in other systems, but again usually due to a component failure, even in those instances.
Powerplant engineering monitor performance trend data and occasionally call out in situ " tweaking" to optimize perfomance.
There seems to be a general quality issue with the engines supplied from MRO's. I believe this would account for a majority of the increased incidents that reflect in the Fed Sec statistics.
Cheers

Wouldn't the main problem with all these engines be that they are reaching the end of their life. You can only rebuild any piece of machinery so many times before it becomes unreliable even with the highest standards in the workshop. The stresses that are put on all the components of a gas turbine are truely incredible.

You can add another to the list,
BREAKING: Qantas Flight 107 from Sydney to LA diverts to Fiji with engine trouble - Flights | hotels | frequent flyer | business class - Australian Business Traveller
OJA I believe

No that is not the problem at all. These engines are the proverbial grandfathers axe.
The critical components are repaired and/or replaced regularly. Stuff wears out and gets replaced all the time.

Fuel valve according to the news. Qantas "emergency".Good grief
It may not be an "emergency", but as far as the punters are concerned .... it's more proof that something's rotten in the state of Qantas! It's more proof that there's a pretty good chance my aircraft won't leave on time, or won't leave, or it will get diverted or something may go bang in the night... in the middle of the Pacific.
All these "perceptions" are starting to make the competition look pretty attractive.
What will change these "perceptions" ?

more qf dramas
friend on facebook this morning...
Both engines cut out as we were attempting take-off from Brisbane airport. We had to halt the take-off and we are stuck on the tarmac. "I'm sure you would appreciate Qantas' strict safety procedures" is the best explanation to date.
flying to Melbourne, delayed for 2 hours

I have to be honest - as a member of the 'general public' and also part of the business community there's two things I take into considering when choosing flights:
1. timeliness ie. depart/arrive on time +15 mins; and
2. reliability ie. I want all my take offs to = my landings without any dramas.
Unfortunately Qantas has lost a lot of its reliability. There's only one way to regain that reliability and thats to NOT have so many engine failures (I use that term loosely). I actually believe VB has a better reliability record than QF and so do a lot of people that I talk to on flights.
Someone needs to do something to rebuild this reputation and soon. Maybe the fact that QF operates older a/c or untested a/c is a factor, I don't know. (and before I get flamed, I'm not an engineer or whatever - this is just my perception as a paying customer) but something has to be done. If I were BG, I'd be kicking butts in Engineering. If Mark Webber's car keeps breaking down, do you kick Mark Webber?
Thats my $1k worth (or whatever I've paid for travel over the last few weeks).

Not quite true Steve.
The engine operated normally from departure Nadi to shutdown in Sydney.
You are no doubt correct that it was changed after the aircraft returned to Sydney but it certainly did not "**** itself" on the way back.
Oh and Troppo; only one engine had a problem despite the fact that you may have seen activity around two.

And that's why I worded it the way I did. Never said two engines had problems. Said two were getting attention and that could have been minimal if nothing at all one of them.

Add the BKK air return to the list.
Not a good look.Another roller broken.
Trend? looks like it to me.
