MERGED: Qantas Decompression ?
Air Crash Investigators is on Channel 7 right now, and guess which episode it is - The Aloha 243 Decompression.
Co-incidence? I think not...
A late schedule change...much more likely!

CASA QF Joke
This is for all the CASA investigators and media out there....its simple
Go back to a QF done D check, look at the check component and more importantly the number of hours spent fixing problems found.
Look at the external MRO and compare the numbers, if they do 1/5th of the extra hours ill eat my hat.
We had workshops and support for all these avtivities today we have nothing left.
Go on ask the question it just so easy to catch these fools out. All those defects not fixed are the swiss cheese of the future. We have been so lucky with total power shut down 15min from landing and the oxy bottle that explodes for the first time ever in history...lets hope we are always lucky....never forget Mr Murphy and his laws!!!!!!

Does anyone have a revised ETA for "Apollo 13" returning back to Syd from Manila?
The hangar will be available in November

AD B747/128 Amdt 3
Notified of this "urgent" AD yesterday entitled Lower Lobe lap joints at wing to body fairing.Could some knowedgable LAME tell us if it has any relevance to the decompression event?What came first?the chicken or the egg??

Last I heard there were two theories on why the bottle blew, one was that the bottle may have been dropped prior to fitting and the other was that the bottle had some water in it and it corroded very quickly due to the high O2 level in the bottle.
As there are no pieces of the bottle left it's hard to tell what really made it blow and we may never know.
As for blaming foreign MROs this was all in house work right back to the D check done in Sydney, sad to say.
The lap join AD is not relevant to this incident but it has to be said that Boeing's engineering stood up extremely well yet again.
Qantas was very lucky again, but I can't help wondering when that luck will run out.

comment from crikey.com.au reporting on the Qantas AGM today
"However he did say all of the 737s in question were back in service, and that the damage to the 747-400 that made an emergency diversion to Manila last month would cost less than $10 million to repair and would return to service in October. "

ATSB Interim report
Here
200804689
I found this interesting
Previous cylinder failures
To explore any historical experiences with the in-service failure of compressed gas
cylinder/s, the ATSB has discussed the issue with several large manufacturers and
users of transportable compressed gas containers, from both aviation and general
industrial operations. On that basis, it appears that the VH-OJK cylinder event has
been without precedent in the aviation arena, in terms of what is known about the
nature of the failure and the aircraft damage sustained. Aviation oxygen cylinders
have failed on-board aircraft previously, however all of the known events have been
attributed to external influences, such as on-board fires or damage sustained during
accident impacts.
Industrial oxygen and compressed gas cylinder failures have also been reported,
however in each instance examined, the failures have been attributed to valve
damage or to improper maintenance activity, resulting in excessive corrosion or
material degradation. While the history of cylinder failure remains under
examination, the characteristics of the occurrence event appear to remain unique in
world-wide experience.

Enough to reach the max landing weight............ I am sure they would not ditch much more thana that!
