Qantas Grounds all A380s

For decades, Australian flag carrier Qantas was known for great service, a young fleet and an unparalleled safety record. In the history of Qantas, one of the oldest airlines in the world, not one single plane has crashed. However, Qantas has had a lot of minor and even major incidents lately: 2008 - a Qantas 747-400 suffered rapid decompression after an explosion in air; 2008 - A330 suffered a rapid loss of altitude in two sudden uncommanded pitch down manoeuvres causing serious injuries; and, finally, November 4, 2010 - a Qantas A380 (the first A380 that was delivered to the airline) suffered an engine failure shortly after taking off from Singapore's Changi Airport.

Only a few minutes after take-off the inner left engine of the A380 with the tail number VH-OQA lost parts of its shell that slammed into the wing, causing a hole of several centimeters. Passengers reported they heard a slamming noise, followed by shaking of the plane. At this point, it is not clear, whether an explosion caused the engine shell to fall off or if the part that fell off caused the explosion by ripping apart cables and fuel injectors. The cockpit crew decided to dump fuel and circled above the Indonesian sea for over an hour before returning back to Singapore. Flight QF 32 safely landed at Changi about an hour and fifteen minutes after it took off to Sydney.

Soon after the incident, Qantas announced it would ground its entire Airbus A380 fleet indefinitely. In my opinion, this is not a very smart move and casts a negative light on Airbus and the A380 specifically, which they do not deserve. Obviously, the issue resulted from a problem with the engine and Airbus does not build aircraft engines. Experts agree that Airbus and the A380 did not really play a role in today's incident. The manufacturer of these engines, Rolls Royce, will have to play a major role in the upcoming investigations. There have already been several issues with these types of engines.

I also need to add here that the media totally blew up this story. The plane landed safely, nobody was really injured and three of the four engines were still running perfectly fine. There have been instances when planes crossed the entire Atlantic with only three out of four engines working. The plane was still in the air more than an hour after the incident! Had this been an emergency like the media pretended it was, the plane would have returned to Changi right away, without dumping fuel. At no point was there any chance the plane would crash. Obviously, it was very scary and uncomfortable for the passengers on board, but their lives were not in danger...

  1. Such failures are expected when you push the materials to their limits. And of course there are no clear boundaries in material sciences. Our knowledge of material fabrication still aint great.
