BRUSSELS (AP) -- Lufthansa has replaced a Rolls-Royce engine on one of its Airbus A380 superjumbos after maintenance checks detected a problem, a spokesman said Wednesday.
Thomas Jachnow declined to specify the problem, but said it was minor and not connected with the oil leaks that have grounded Qantas and Singapore Airlines superjumbos using the same type of engine.
He says the aircraft in question is back in service, and that scheduled A380 flights have not been affected by the engine change.
Qantas and Singapore Airlines discovered oil leaks on their planes 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 Qantas immediately grounded its entire fleet of A380s while it investigated the cause.
On Wednesday, Singapore Airlines followed suit.
Jachnow said Lufthansa management had decided on the engine swap as a precaution after consultations with Rolls-Royce.
"For us and for Rolls-Royce this was reason enough to replace the engine," he said. "This will in no way affect our A380 passengers."
Jachnow said customer confidence in the aircraft -- the world's largest commercial passenger plane -- remained high, and that the airline had not recorded any spike in cancellations since last week's incident.
London-based Rolls-Royce, which manufactures the engines for A380s used by Qantas, Singapore Airlines and Germany's Lufthansa, had recommended a series of checks on the Trent 900 engines.
Rolls-Royce shares were down 0.8 percent in London trading on Wednesday.
