QF32 388 - emergency landing in SIN after Engine failure

[oz_mark]

The guy was implying that the higher rating created extra stresses that SQ and LH didn't experience. That would seem plausible with the same mechanical engine and different software (from a theoretical POV). But doesn't stack up with the engine being rating higher and also the small 2k difference and of course your knowledge and experience.

Just trying to account for how Qantas have found one thing and the other airlines another. There is an article in the Australian this morning that would suggest it is at least one of the lines of enquiry:

HIGH-POWER take-offs used by Qantas A380s on trans-Pacific routes could be responsible for potentially dangerous oil leaks now under scrutiny.


The leaks may be a possible factor in last week's engine explosion near Singapore.
Engineers believe the higher thrust levels at which the carrier operates its Rolls-Royce Trent 900 engines may result in resonating vibrations that cause oil lines to crack

How did we miss the QF A380 incident in south Korea? Good to see that the normal standards for accuracy are being used.

QF32 A388 makes emergency landing in SIN after Engine failure

Some "newspapers"actually went further than this and added in the cardiac arrest and subsequent death of an elderly man on a JQ flight SIN-ADL the same week

 

[jb747]

Did you hear about the A380 dual engine failure that an airline had, due to finger trouble? I didn't think so, 'cos it wasn't QF.

 

[Oneworldplus2]

I just copied the article people. Mainly to just expose to other members what else is being said about QF in the public media.

I love how they throw in a few JQ incidents, just for good measure.

Still part of the QF Group? Look in the "QF WP wish-list thread" and how a large amount of WP's want more benefits while flying JQ?

Fixed. Sorry, my bad.

Who was that?

Was a busy day then. Emirates had a problem with the fuel system there the same day!

(Qantas, Emirates - easily confused!)

Gotta laugh about the RR announcement that they have pinpointed or made 'good progress' to an engine model. That's not a pinpoint - its a barn door, but the press lapped it up. Their integrity is still suss - they have not supplied specifics.

"The leaks may be a possible factor in last week's engine explosion near Singapore.
Engineers believe the higher thrust levels at which the carrier operates its Rolls-Royce Trent 900 engines may result in resonating vibrations that cause oil lines to crack. "

Show me a bit of cracked fuel line. I'd like to believe that, but I am pretty sure resonance is fully ,widely an extensively tested and anticipated. On paper RR could eliminate that prior R+D tests on the engine bench, although pylon anchorage could skew the numbers. I dont know the oil line material, but I would expect it to be metallic or braided, and well proven. Resonance would imply the hose is floppy and not well anchored. Unlikely. Even with resonance, QF implied that the engines were practically brand new. Then we get max heat/cooling rep cycles, which in jet engine 101 speak is well anticipated. If its stainless steel, its tough.

Thus the hose fastening coupling/join points seem a likely suspect, and if they are not done right, could allow for end resonance, then leaks. The temperature at which you tighten, and pre-oilfilming makes a big difference in using a tension wrench.

Air is a lot denser at colder temperatures, but given SQ and LH take off in the same places fully loaded, I'm not convinced that path of thinking will lead anywhere. QF flys against the tradewinds - nah not buying that either.

"In August a Lufthansa <LHAG.DE> A380 en route to Tokyo from Frankfurt shut down a Rolls engine shortly before landing because of a change in oil pressure"
Clever pilot!! What did the report say afterwards?

I'm still peeved RR has not announced results on the rotor that broke. After this the software will probably be trained to sense overspeed or resonance or oil pressure drops and react. And if the oil lines need a few more clamps , its an easy fix.
If its a resonance or harmonic thing, then sell!

That’s like blaming Iberia for Ba’s pension deficit, same group, but the issues aren’t remotely related. They’re each run completely differently

I beg to differ. Jetstar was formed by Qantas and is part of the same company as it's parent. IB and BA are two companies that have mergerd. That's two different kettle of fish Sam. Maybe CX and dragon air could be considered as a better example. Maintanence that works on QF would also do JQ planes.

QF do no work what so ever on the A320's as they don't have the qualified staff, it's done byJQ at the maintenance base in NTL which also does some of the QF 717 work, while the A330 heavy work is down in Manilla for both companies I believe.

It would have been more accurate to include Sunstate/Eastern etc in the mix than JQ as QF does have more involvement in the ops.

QF and JQ work closely together for frequent flyer benefits, but in terms of aircraft operations, maintenance, staffing entities it's fair to say they are unrelated in any way apart from sharing a parent.

 

[jb747]

No. Maintenance, pilots, etc, are all separate.

Much as the Australian press takes pot shots at Qantas, in its home country Rolls Royce seems to be taking a bit of stick from its home press (although to be fair the UK press does seem a bit more balanced).

So Rolls needed to decouple this event from the Trent 1000 failure.

Their comments seem to suggest a design issue common across the variants that the airlines fly. If not, they probably would have said it was specific to the QF variant.

I guess we'll find out in due course....

While a list of QF incidents over the past 5 years may be interesting reading, without being placed in context by comparing with other similar airlines (similar fleet size and mission types) its meaningless when it comes to determining anything related to maintenance or safety standards.

Don't let that get in the way of a good story

Again media not checking their facts. JQ don't even fly SIN/ADL however they did give the flight number of JQ62 which is in fact SIN/DRW/MEL.

If they're consistently inaccurate in reporting aviation matters it's probably a fair indication of the accuracy of anything else that happens on this planet.

Note to 'journos': www.google.com then enter "JQ62" & voila!

ABC News has just reported the SIA have now grounded 3 of their A380's.

The plot thickens!
