Qantas Flight 32 was a regularly scheduled passenger flight from London to Sydney via Singapore. On 4 November 2010, the aircraft operating the route, an Airbus A380, suffered an uncontained failure in one of its four Rolls-Royce Trent 900 engines. The failure occurred over the Riau Islands, Indonesia, four minutes after takeoff from Singapore Changi Airport. After holding for almost two hours to assess the situation, the aircraft made a successful emergency landing at Changi. No injuries occurred to the passengers, crew, or people on the ground, despite debris from the aircraft falling onto houses in Batam.On inspection, a turbine disc in the aircraft's number-two engine (on the port side nearer the fuselage) was found to have disintegrated, causing extensive damage to the nacelle, wing, fuel system, landing gear, flight controls, and engine controls, and a fire in a fuel tank that self-extinguished. The subsequent investigation concluded that the failure had been caused by the breaking of a stub oil pipe, which had been manufactured improperly.The failure was the first of its kind for the A380, the world's largest passenger aircraft. At the time of the accident, 39 A380s were operating with five airlines: Qantas, Air France, Emirates, Lufthansa, and Singapore Airlines. The accident led to the temporary grounding of the rest of the six-plane Qantas A380 fleet. It also led to groundings, inspections, and engine replacements on some other Rolls-Royce-powered A380s in service with Lufthansa and Singapore Airlines, but not in the A380 fleets of Air France or Emirates, which were powered by Engine Alliance engines.
