A QANTAS jet that suffered a mid-air engine failure in 2010, sparking the grounding of its entire A380 fleet, has finally taken to the skies again.

Stop shitting up other people's threads.
Tsuru wrote:Yes it was. Before, the proper procedure would be to cut away any damaged material and patch it, typically further obscuring any fatigue cracking that may exist in an area of the aircraft already not seen very often, as it is accessed only by mechanics to work on other stuff, such as the flight controls (as opposed to the aircraft skin, which is seen by everyone all the time by comparison)
There is a Chinese cargo 777 being repaired in Copenhagen at the moment which suffered a tailstrike in much the same fashion as the JAL 777 did, and they took the entire tail off to replace the whole rear pressure bulkhead as a single structure. I remember seeing some pictures posted, but I can't for the life of me remember where. But I'm sure your collective Google-fu will find them.
Boeing seems to be doing rather well with all of those expensive repairs that they need to do at the moment...
Neither is mine, so let's leave it at thatMock Cockpit wrote:In a semi-related "crappy national airlines in One World" aside]Now this I never expected to happen. I'm waiting with baited breath for the gritty details as to how they were able to pull this repair off without replacing the complete main spar or wing (if that's not what they did). Knowing how delicately these wings are produced (frictionwelded metal, cured in an autoclave) and the extent of the damage, I literally have no idea how it was possible to fix without replacing complete structures, and still guaranteeing a lifetime of safe operation.Strictly speaking it's not necessary, but this extensive (and expensive) way is basically to guarantee nobody has a chance to botch it in ays that leaves chances for hidden fatigue cracking to develop in a relatively hidden area of the aircraft. It's not really that complex a procedure to replace a bulkhead, remember that the 777 is fly-by-wire and there are no control cables to re-attach and re-rig (just electrical, bleed air and hydraulic lines), and as such there is no chance of the aicraft handling differently after the repair. (it's just a little heavier and thirstier, and might develop some trim drag)Mock Cockpit wrote:http://www.airliners.net/aviation-forums/general_aviation/read.main/5120854/
Be interested to know whether these newer planes are designed so that replacing the entire tail and/or pressure bulkhead is now the only way to repair a tail-strike.chokonen888 wrote:Ehhhh Tsuru, English isn't his native tongue

Would feel funny if it's just from this repair... one side 250 kg heavier...
Mock Cockpit wrote:In my experience of Qantas, 240 kgs of that would come from the weight gains of the crew in the 18 months since the incident. Last time I flew Qantas one of them was so fat as he moved the trolley along the aisle he used his guts to push it while pouring drinks. I didn't know whether to be horrified or impressed.
Switched over to Air France after that, nothing but young Japanese CA and old matriarch-type French headmistress FA....service sucked though, but better than any 'merican airline currently.
