SYDNEY — Tests uncovered oil stains in three Rolls-Royce engines on Singapore Airlines' A380 superjumbos, prompting the airline to yank the planes from service Wednesday just two days after Qantas announced troubling oil leaks on its A380s.
The oil on the Qantas and Singapore planes was discovered during tests prompted by the explosion of a Rolls-Royce engine on a Qantas A380 during a flight from Singapore to Sydney last week. The plane made a safe emergency landing in Singapore, but the Australian airline immediately grounded its entire fleet of A380s while it investigated the cause.
Singapore Airlines said it does not know whether the oil stains found in its engines have any connection to the engine oil leaks found on Qantas, but was temporarily pulling the planes from service as a precaution. The planes, in Melbourne, Sydney and London, will be flown to Singapore without passengers, where they'll be fitted with new engines.
"We apologize to our customers for flight disruptions that may result and we seek their understanding," airline spokesman Nicholas Ionides said in a statement.
Twenty planes operated by Qantas, Germany's Lufthansa and Singapore Airlines use the Trent 900 engines. With the decision by Singapore, nine aircraft with the engines have been grounded.
