Qantas A380 grounded in Los Angeles after mystery problem with hydraulics
Qantas A380 grounded in Los Angeles after mystery problem with hydraulics
This is going to be interesting.
Off shore maintenance Alan? Its not like anyone warned you!
Qantas is yet to determine the exact cause of the problem but sources say one of the aircraft's hydraulic systems appears to have been contaminated with the wrong fluid.
Engineers discovered filters clogged with a black, molasses-like substance, and have since replaced several filters and fluid pumps in what is known as the "yellow" hydraulic system.
The A380 returned from several weeks of maintenance at Lufthansa Technik's base in Manila in the Philippines on June 20, and flew a return flight from Sydney to London, and then onto Los Angeles before it was grounded there last Thursday.

The aircraft in question has had no end of issues since the ferry flight back from Manila.
This is what they wanted, no LAME oversight and a handful of non-licenced Ops Managers to over see the paperwork.
The Texan and the Clogman wanted this, let the Clogman answer to the board why his centre of excellence is such a sh1t fight.

Classic symptoms of overheated Hydraulic fluid turns to Black Sludge..
A380 what a crap aircraft, overweight, slow and no better on fuel consumption than a B744....A Billion dollar exercise is "Keeping up with the Jones"
Resale value....zero!

Thanks hard worker for that I didn't know it. What's the result of the overheating and sludge? Do pumps , actuators and flexible lines have to be replaced? Any info would be appreciated.

Experience
Had it happen on an A340 Green system, both 1 and 4 pumps caused the hydraulic fluid to turn to black sludge...ended up changing main delivery lines and flush the system over and over....what caused it? Never did find out but suspected air in the system...airbus are very difficult to bleed all the air from the hydraulic systems...you end up bleeding on the pressure/case/supply lines on the pumps..

Overweight? .. perhaps - they did build the wing for another 100 tonnes of TOW, so they could have saved some weight there. Current production machines have an additional 10 tonnes approx disposable load from a combination of reduced empty weight and increased TOW.
Slow? .. same cruise speed as a 747 - does 0.86 mach quite nicely. Fuel consumption does start to climb a bit after that though.
Fuel Consumption? .. yes it does burn about 20% or 25% more, but then for the same passenger configuration standard, it can carry 40% to 50% more pax.
Airfield performance? .. beats the stuffing out of a 747.
Altitude capability? ... It's great being able to climb above the traffic as an initial altitude ... 3,000 to 4,000 ft advantage over others.
Range? .. Dallas - Sydney with 380 pax (with a very high percentage of premium seats). Nothing else can do that. (777 or 787 can't do the premium end like the A380)
I'll certainly never see full fuel tanks.
And don't forget this is the relative start of its development cycle.
It is not the answer to everything and we certainly need a large fleet of aircraft such as the 777, 787 or A350, however it is very good at what it does. The 747 is still a great aircraft and a stunning example of aircraft design. It still does some things better than anything else, but so does the A380.

Reliability & Manpower
You forgot to mention how unreliable and how much manpower the A380 absorbs...triple the amount compared to a B744....wrong aircraft type...the A350 and New Gen B777 are the hub busters, the A380 takes too long to turnaround....bottom line its too big not the ideal aircraft...

As for jacking incidents, who knows what happened there. And comparing overseas MRO's to SAM is like comparing apples to oranges. We don't have a heavy maint facility for this aircraft.
There are quality engineers all around the globe. Many in QF are from different backgrounds of maintenance, and from other countries too. What makes a real difference to maintaining a quality product are the facitlities, procedures and ratios of qualified supervision in place. IMHO Sydney had the best many years ago (but it wasn't "worlds best practice").
