Safety investigators in Australia on Monday delivered their verdict on the cause of an engine failure which forced an Emirates A380 plane to abort a flight from Sydney to Dubai.
A report by the Australian Transport Safety Bureau said a Sydney home was showered in debris from the A380 after one of its engines exploded shortly after takeoff.
Emirates flight EK413 from Sydney to Dubai was just 30 minutes into its journey on November 11 last year when the engine failed, the report said.
The air-safety investigators found the explosion was caused by the breakup of high pressure turbine nozzles that dislodged and blasted a hole in the engine casing.
The incident was the third involving an Emirates A380 in two weeks and the manufacturer had already begun to increase its monitoring of engines, the report said.
During the previous flight of the aircraft involved in November's incident, the monitoring system had detected problems with the engine and alerted Emirates to the problem, it added.
The airline scheduled the engine in for inspection on its return to Dubai - but the part exploded just minutes after takeoff, investigators said.
The flight, carrying 380 passengers and 28 crew, was about 9,000ft above Sydney when an engine temperature warning guage was activated and the engine shut itself down.
"The crew jettisoned excess fuel and returned the aircraft to Sydney for a safe landing and disembarkation of the passengers and crew," the report said.
It added that the faulty nozzle had been replaced on all Emirates A380 aircraft following the incident.
