On 3rd November 2010 there was an incident involving the failure of the number two Rolls-Royce Trent 900 engine powering a Qantas A380 flying from Singapore to Australia.
The aircraft made an emergency landing in Singapore after shedding the aft section of the cowling and other engine parts over Indonesia. Photographs of the aircraft show damage to the adjacent wing structure, suggesting that the leading edge was penetrated by uncontained engine debris.
The number two engine appears to have suffered a failure of the high end energy rotating section of the engine. From photographic evidence there is a hole in the lower and upper section of the wing where some type of engine debris has gone through.
Also notable is that when the aircraft arrived at Singapore the aircraft already had its landing gear opened suggesting there was an emergency deployment of the landing gear. The leading edge slats were also not deployed whereas the trailing edge flaps are deployed.
Only further investigation will show what really went wrong. Luckily incidents like this are very rare.
