Alan Joyce, the head of the Australian airline Qantas, says oil leaks have been found on multiple engines of its Airbus A380 fleet.
The Qantas A-380 jets remain grounded after an engine came apart on a flight from Singapore to Sydney. The oil leaks are an unexpected and unacceptable condition of the jet engines.
The airline and investigators are also looking for a piece of turbine that is missing from the jet engine — part of the debris that showered an Indonesian island during the incident.
