A "leaked" and unconfirmed PDF document first published by Crikey.com purports to show pictures of the damage done to a Qantas A380 on November 4 when it suffered an un-contained engine failure and shed parts over Indonesia. Photos in the document show a failure that sent debris toward the fuselage, gashes in a wing, serious damage to a flight control drive motor, severed wiring, damage to a forward spar and a large fuel pipe that's torn open. (Click through for images.) The document says the forward spar was "penetrated and is damaged extensively." The photos have not been officially confirmed by Airbus or Qantas. Separately, Richard Woodward, vice-president of the Australian and International Pilots Association said of the damage, "the amount of failures is unprecedented." Qantas grounded its six aircraft fleet of Airbus A380's following the accident but announced Tuesday that it is ready to resume some A380 operations after "extensive checks with Airbus and Rolls-Royce." The airline is not ready to restart its longest A380 flights and Rolls-Royce is still busy dealing with complications the events have imposed on its supply chain.

It sure looks like a damaged A380.
What’s uncomfirmed?
If it ain’t Boeing, I ain’t going.

Only fly Pratt & Whitney if you want to get to your destination every time.
The gremlin from ‘Nightmare at 30,000 Feet’ has been busy.
Another spin on Rolls-Royce’s old airline slogan “take your breath away”.
CFM isn;t bad either.
isn;t = isn’t
Is this that flight that I read about that had extra pilots on it due to it also being the regular pilot’s annual checkride?
If the Airbus 380 can sustain THAT much damage from the RR engine failure and land safely, it must a pretty damn good airframe. I’ve read how the five pilots on board brought it in successfully — quite a story.
You need to look for RR engines. You want to fly GE engines instead.
"Holy Toledo !"
Anybody looking into aircraft mechanics named Mohammed?
Anytime you cut fuel lines or into a spar, that is seriously bad Ju-Ju.
Lucky they got it down.
Yes, they had a senior Captain aboard observing the plane’s Captain, and an even more senior Captain aboard observing him.
There was considerably over 100 years of experience on that flightdeck because the First and Second Officers were also quite experienced.
Damage overview:
* massive fuel leak in the left mid fuel tank (the beast has 11 tanks, including in the horizontal stabiliser on the tail)
* massive fuel leak in the left inner fuel tank
* a hole on the flap canoe/fairing that you could fit your upper body through
* the aft gallery in the fuel system failed, preventing many fuel transfer functions
* fuel jettison had problems due to the previous problem above
* bloody great hole in the upper wing surface
* partial failure of leading edge slats
* partial failure of speed brakes/ground spoilers
* shrapnel damage to the flaps
* TOTAL loss of all hydraulic fluid in the Green System (beast has 2 x 5,000 PSI systems, Green and Yellow)
* manual extension of landing gear
* loss of 1 generator and associated systems
* loss of brake anti-skid system
* unable to shutdown adjacent #1 engine using normal method after landing due to major damage to systems
* unable to shutdown adjacent #1 engine using using the fire switch!!!!!!!!
Therefore, no fire protection was available for that engine after the explosion in #2
* ECAM warnings about major fuel imbalance because of fuel leaks on left side, that were UNABLE to be fixed with cross-feeding
* fuel trapped in Trim Tank (in the tail). Therefore, possible major center of gravity out-of-balance condition for landing.
Qantas A380 Sustained Worse Damage than First Thought By Gerald Traufetter
The exploded engine was scary enough. But in the days following the emergency landing of the Qantas A380 in Singapore, it has become clear just how dangerous the situation was. Multiple systems on the aircraft failed and a disaster was only narrowly avoided.
Rarely had so much flying expertise been assembled in one cockpit. A training pilot was sitting behind Captain Richard de Crespigny, who was completing his annual flight test. Sitting next to them was a third captain whose job was to supervise the training pilot. Together, the Airbus A380 operated by Australia's Qantas Airways had a total of 100 years of flying experience sitting in its cockpit. Four minutes after takeoff from Singapore, that accumulated expertise was suddenly in great demand. At an altitude of 2,000 meters (6,560 feet), engine two of the double-decker aircraft exploded. The loud bang of the detonation had hardly faded away before 53 error messages appeared on the monitors.
Upon reading the matter-of-fact messages, the five pilots realized immediately how serious the situation was. Kerosene was leaking from two of the 12 fuel tanks, which meant that the plane could catch fire at any moment.
"It was unbelievably stressful. But in a situation like that, you have no choice but to keep on going," says Richard Woodward. The captain knows what he is talking about. He also flies the A380 for Qantas, is the vice president of the International Federation of Airline Pilots' Associations (IFALPA) and has looked after the crew since the near-catastrophe almost two weeks ago. "The crew has dealt with this situation extraordinarily well," Woodward reports. "They're like horseback riders who, after a fall, are eager to get back on their horses."
Failed to Activate
The men have given him their accounts of those dramatic moments in the air. There were no warnings before the engine exploded -- no change in oil pressure, no unusual vibrations, nothing. When the explosion occurred, the captain quickly pressed an emergency button that activates an automatic extinguishing system when there is an engine fire. But the system failed to activate. "It was clear to him at that point that there must have been more damage," says Woodward.
One of the training pilots ran back into the cabin, where he saw the holes in the wing caused by loose metal parts from the turbine. As a result, De Crespigny could not dump fuel properly to reduce the weight of the fully fueled aircraft for an emergency landing. He was also unable to pump kerosene from the back to the front of the aircraft, causing it to become increasingly unstable as kerosene escaped.
The incident raises serious questions for both engine manufacturer Rolls-Royce and Airbus. "How could there have been this much loss of function?" asks Woodward.
One of the two hydraulic systems failed and important connecting cables were severed, including those leading to the outer engine one. Although the pilot could still control the engine manually, it could no longer be shut off, so that firefighters had to smother it with extinguishing foam after the emergency landing.
Bad Brakes
"This raises the question of whether the aircraft is improperly designed," says Woodward. "Apparently certain connections are not redundant; or the two cables are positioned so close together that the shrapnel destroyed them simultaneously."
The aircraft manufacturer is defending itself against such accusations. The aircraft, says Airbus spokesman Stefan Schaffrath, was "controllable until the landing," and the autopilot continued to function. "There are two separate hydraulic and electrical systems," Schaffrath adds. But some of the brakes were no longer working properly. Luckily, the pilots were able to land in Singapore, which has a very long, 4,000-meter runway.
Another dramatic aspect of the emergency landing was that an anti-lock system also stopped working. Three tires burst when the plane touched down as a result, sending sparks into the air. "And that was with two holes in the tank!" says Woodward.
Very Conservative
At least the reason for the engine explosion is now clear. Last week, Rolls-Royce identified a defective part in the turbine, which caused an oil leak that led to the fire. Of the superjumbo jets delivered to date, 20 are affected by the problem, including three at Lufthansa. The defective engine part will gradually be replaced.
Qantas pilot Woodward is pleased that his company has made a "very conservative safety decision" to temporarily ground the A380. But he does wonder why the other airlines potentially affected by the engine defect are not taking similar precautions.
Lufthansa points out that it has such short maintenance intervals that dangerous oil leaks are bound to be discovered. But Woodward isn't convinced, saying: "Our plane had just returned from maintenance in Frankfurt, and the accident happened nonetheless." Translated from the German by Christopher Sultan
