ETIHAD, the Abu Dhabi based airline, and Heathrow”s major latest arrival, has chosen two versions of Rolls-Royce Trent engine family to power the latest phase of its fleet expansion. The deal involves Trent 900 engines for four Airbus A380s and Trent 700s to power 12 A330 twinjets. Including long-term TotalCare maintenance agreements covering all the engines, the contract is valued at $950m. Etihad”s initial Trent selection was announced at last summer”s Farnborough Air Show when the airline ordered eight, four-engined, ultra-long-distance A340-600 airliners, for which the Trent 500 is the sole engine. Etihad becomes the sixth airline to select Rolls-Royce power for the A380, taking total Trent 900 orders to 84 firm and option aircraft, and giving the engine a 51% market share.
