Airbus A380
On 4 November 2010, Qantas Flight 32 was flying from Singapore Changi Airport when the number 2 engine failed, causing some damage to the plane, and forcing it to return to Singapore.  Nobody was injured, but debris from the airplane fell onto the island of Batam, in Indonesia.  Investigations found that the Rolls-Royce Trent 900 engine leaked oil, causing an explosion.  Other Trent 900 engines had similar problems and many engines had to be replaced and the FAA issued that all Airbus A380s currently in service are required to go under mandatory inspections before takeoff to prevent future engine problems.
