What happened?
It is too early to tell. But what seems clear is that there was a catastrophic failure on the engine side of the fuselage on the left wing shortly after the plane took off from Singapore bound for Sydney. Passengers said they heard loud explosions and seeing flames. The debris appeared to be the engine that landed on the Indonesian island of Batam, near Singapore. The aircraft returned to Singapore and landed safely.
What was the damage to the plane?
Aviation experts believe that as the engine to lose its protective cover, the turbine blade sections off. A photograph taken by a passenger from inside the plane shows a small hole in the left wing, possibly caused by debris. When the plane landed, the engine side, on the edge of the wing, apparently could not be turned off and was doused by firefighters, indicating possible damage to the aircraft's controls.
Who is responsible?
The great Trent 900 are manufactured by Rolls-Royce in Derby, and is the British engine manufacturer is immediately in the spotlight. "This incident is a particular concern for Rolls-Royce, and I think it has some explaining to do," said an aviation analyst, speaking anonymously. Although Qantas has been ordered to update maintenance procedures two years ago from an oxygen tank exploded on a Boeing 747 from the airline, the rupture of the fuselage, maintenance is considered less likely to be a cause of the incident today. This is partly because the engine was so new - the plane was built in 2008 - and because the engines of long-haul aircraft carry less stress they are subjected to fewer takeoffs and landings.
What has been the response?
Rolls-Royce said that assist in investigations, but declined further comment until it knew more. major concern of the company will find out if the engine failure was a timely incident caused perhaps by a manufacturing error, or could be due to a more general fault with the design. Qantas A380 land his six, followed soon after by Singapore Airlines. But other airlines operating aircraft vast - Air France, Lufthansa and Emirates - will continue its use. There is a minor issue for Emirates and the A380 are equipped with different engines, the Engine Alliance GP7000 made by the U.S. companies General Electric and Pratt & Whitney.
How serious was the incident?
A380 can operate safely in just two engines and some experts say that there was no real danger. But others warn that it was potentially more dangerous than it might first appear, especially considering that the sections of the engine failure could have caused more damage to the band and motor controls for the next appear to have been damaged. "It sounds like it could have been something quite hairy. It would not surprise me if the team did an outstanding job landing the plane," said an aviation analyst.
How often as an engine explosion happened?
Are rare, and when carried out rarely cause casualties. Much of this is due to changes introduced after the tail engine mounting a third of United Airlines DC-10 flew in 1989, spewing debris across stun hydraulic lines and flight controls. The plane broke up on landing in Sioux City, Iowa, killing 112 of the 296 passengers and crew on board. Since then, airlines have been designed for engine exhausts are less likely to damage control systems.
