The only certification requirement as far as I know in that regard is that a blade failure in the fan section should be contained. There is no requirement to contain parts should there be a catastrophic failure in the turbine section.MainPower wrote:I always though that the casing of an engine should protect part getting outside the engine?
However I'm sure this happened before...
Not sure if I'd go that far. This is the first failure of its type since it's been in service, and it could just as easily be a manufacturing flaw with this particular engine.MainPower wrote:Could I say a reliability issue of the Rolls-Royce Trent 900 engine?
Pretty standard stuff for the engineers union in Australia. Every incident involving a Qantas aircraft, however small, is used by them to advance their own agenda and take potshots at the QF management.Stef wrote:Coming from:Qantas engineers seized on the incident to question the airline's safety. Australian Licensed Aircraft Engineers Association secretary Steve Purvinas said there were just 24 licensed engineers working on Qantas planes worldwide, when there should be more than 100.

Joyce said the most likely cause was a materials failure or a design flaw in the huge Rolls-Royce Trent 900 engine, which could land the British manufacturer with a huge legal bill.
"Qantas will not return its A380 fleet to service until confident the issues have been identified and resolved," Joyce said.
Are there any other A380 operators grounding their planes? Or is this a Qantas maintenance problem?"On three of the engines what we have found is slight anomalies - oil where oil shouldn't be on the engines - and we are just trying to check what the cause of that could be," he said.
Singapore had grounded their A380s also. Don't know if or when they resumed flying.MainPower wrote:Are there any other A380 operators grounding their planes? Or is this a Qantas maintenance problem?
An uncontained engine failure has recently occurred on a Rolls-Royce
Trent 900 involving release of high energy debris and leading to damage
to the aeroplane.
Analysis of the preliminary elements from the incident investigation shows
that an oil fire in the HP/IP structure cavity may have caused the failure of
the Intermediate Pressure Turbine (IPT) Disc.
This condition, if not detected, could ultimately result in uncontained
engine failure potentially leading to damage to the aeroplane and hazards
to persons or property on the ground.

Cockpit recorder overwritten in Qantas A380 engine incident
By David Kaminski-Morrow
Investigators have discovered that the cockpit-voice recording of the Qantas Airbus A380 engine failure was overwritten because the adjacent engine could not be shut down after the aircraft landed in Singapore.
But while the flight-data recorder stored parameters from the entire flight, the ATSB states that its team in Canberra have only retrieved part of the cockpit-voice recorder audio.
It says that the failure of the adjacent outboard left-hand engine to shut down, after the stricken A380 landed in Singapore, meant it continued to supply power to the recorder.
Audio from the time of the in-flight engine failure - some two hours beforehand - was "overwritten", the ATSB adds: "That said, elements of the available audio are expected to be of assistance to the investigation."
Who's call is this? Qantas? Insurance company? Engine company? Airbus?Mark B. wrote:Rumors are spreading that the A380 involved is damaged beyond economical repair.
