This is the essence of the question being asked by Captain Fantastic, formerly known as Richard de Crespigny, the handsome Aussie who along with his crew, safely landed Qantas Flight 32 in Singapore last November.
The A380 experienced a dramatic engine failure shortly after takeoff and investigators are still sorting out all that happened that day. In keeping with "Jaws syndrome" theory then, every out-of-the ordinary event since, whether on a Qantas plane, a Rolls-Royce engine or an A380 is blockbuster news and Captain Fantastic has had enough. In an email yesterday, Richard told me,
"Today's aircraft engines and aviation are safe. So safe in fact that when "Shit Happens" it is not an issue that it has happened - but rather how the crew respond to manage it, maintain safety and comfort the passengers."
As the man responsible for leading a team of four other highly experienced pilots through so many system failures it took them 2-hours just to sort through the error messages, one must grant some weight to his opinion. He rightly reminds me that just last year, the U.S. National Transportation Safety Board urgently recommended the modification and inspection of GE CF6 turbo fan engines after four safety events in two years. Eight engine events on Pratt & Whitney 4000s resulted in the FAA ordering inspections of almost one thousand engines at the end of last year.
All of this goes to prove the point that designers and maintenance technicians do make mistakes, and sometimes even the most reliable products will fail. At times like those, he's right to suggest
"the professional well trained and experienced pilots up front, with the considerable support resources available at the home base - made the right and safe decisions."
Capt. de Crespigny is not alone in this opinion. On a recent Lufthansa A380 flight, I spoke to Capt. Geert Pruess and First Officer Harald Tschira who also proclaimed unfailing confidence in the A380 and its engines and their ability to handle any technological burp along the way.
To these men and the rest of the flying public I want to make two points - one obvious 1) Both the A380 and its power plants are new technology and 2) for all the tests and computer-generated failure analysis, there is no way to completely understand in advance the things the machines will do in the real world. In fact, the opposite happened on Flight 32.
The very failure of the engines and so many flight control and engine control systems showed the unanticipated consequences from an uncommon but not unknown event - uncontained engine failure.
