Quantas A380, Rolls-Royce, Trent 900
Singapore Airlines tests have uncovered oil stains in three Rolls-Royce, Trent 900 engines on it’s A380 superjumbos, the planes were withdrawen from service Wednesday.
The Trent 900 engines are in use on the Qantas A380 aircraft, one of which was forced to make an emergency landing last week Thursday in Singapore after a mid-air blowout minutes taking off from the city-state’s Changi Airport.
Australian airline, Quantas, has grounded its entire fleet of A380s while it is investigating the cause, the fleet is expected to be grounded till early next week.
The A380′s, in Melbourne, Sydney and London, will be flown to Singapore without passengers, where the engines will be replaced.
It roumord is that a bearing or seal problem is th cause of the oil leaks on the Rolls-Royce engines, should this be the case we would expect to see limited operations imposed on the A380′s under very strict conditions.
Singapore Airlines said that the problems on three of its 11 A380s are precautionary and unrelated as the oil stains oil leakage in the Qantas engines.
It has emerged that the dammage to the Qantas’s A380 that happend when the No.2 engine exploded, knocked out multiple systems including the left-side fire extinguishers, the auto-brakes and the anti-skid system.
Lufthansa’s A380′s also use the Rolls-Royce, Trent 900s. A380s flown by Emirates and Air France use engines manufactured by the Engine Alliance, a 50/50 joint venture between GE Aircraft Engines and Pratt & Whitney.
