An Airbus A380-861, operating flight EK416 from Sydney-Kingsford Smith International Airport, NSW (SYD), Australia to Dubai Airport (DXB), UAE, returned to Syndey after experiencing engine problems. Engine nr. 3 was shut down in flight.
Flight EK416 took off from runway 34L about 22:00 local time. The airplane climbed to FL190 and made a right turn over Mudgel for a return back to Sydney Airport.
The flight landed safely on runway 34L at 23:35 local time.

The investigation found that the increase in the exhaust gas temperature and subsequent engine shut down was a result of significant internal damage that had initiated within the high pressure turbine (HPT) module. The damage had resulted from the effects of HPT stage-2 nozzle distress, likely caused by exposure to hotter than expected operating temperatures. The nozzle distress led to eventual failure and separation into the gas flowpath. Over the preceding weeks there were two other engines within the operator’s fleet that had experienced a similar problem, and a number of steps had been taken by the manufacturer to address the issue, including the increased monitoring of distress development. During the previous flight, the engine health and trend monitoring program had identified a performance trend shift with this particular engine, and it was due to be inspected upon return to the main base in Dubai.
