Superjumbo fleet grounded after engine tests reveal oil leaks

Tests uncovered oil leaks in three Rolls-Royce engines on Qantas’ grounded Airbus A380s, the airline’s chief executive officer said today, as engineers tried to zero in on the cause of an engine failure on board one of the carrier’s superjumbo jets last week.

Australia’s national carrier grounded its six double-decker A380s, the world’s newest and largest airliner, after an engine burst minutes into a flight from Singapore to Sydney last week, scattering debris over Indonesia’s Batam island.
