Rolls-Royce is to fit new oil feed systems to 21 aircraft powered by its Trent 700 engines to end the engine shutdowns that have forced three aircraft to make emergency landings.
Inadequate lubrication of a bearing in the Hispano-Suiza gearbox have forced three aircraft to land using one engine.
`The Trent 700 is fairly new,’ said Rolls-Royce.
`It’s not uncommon for problems to appear in the early life of the engine.’
The Trent 700 is fitted to 21 aircraft owned by Cathay Pacific, Dragonair and Garuda, the last of which has not been affected by the problem. Cathay Pacific and Dragonair decided to ground their fleet.
The Trent 700 was introduced two years ago to power Airbus A330 aircraft. So far 90 have been sold with 69 awaiting production. All will receive a refit with the new oil feed system.
