A Qantas A380 operating QF93 from Melbourne to Los Angeles was diverted to Sydney after an engine shutdown due to an oil leak in engine number 2. The aircraft dumped fuel and made a safe emergency landing. Qantas said in a statement that an indicator had come on in the cockpit and the decision was made to divert.
“The captain made the decision to land in Sydney to have the fault fixed rather than continuing on the 14-hour flight. We apologise to passengers for the interruption to their journey but safety is always our first priority. Our focus is now getting them on their way as soon as possible” Qantas wrote.
