After a two week delay, Emirates (EK, Dubai Int'l) hopes to take delivery of the first of fifty Rolls-Royce-powered A380-800s on December 16, reports Bloomberg.

Tim Clark, President of Emirates, had earlier indicated that the Trent 900 engines had some technical issues, related to fan blade wear. The two companies have now reached an agreement over the technical problems. Rolls has agreed to finance measures to counteract the performance and maintenance issues, which are believed to stem from Emirates’ desert location.

Emirates had previously bought GP7000s from General Electric's and Pratt & Whitney's Engine Alliance for its first ninety A380s. The switch to Rolls-Royce was understood to bring efficiency and other improvements. The deal with the British engine manufacturer was penned in April 2015 and reported to be worth USD9.2 billion, plus a through-life maintenance contract.

The Trent 900 currently has the market advantage over the GP7000 with Asiana Airlines, British Airways, China Southern Airlines, Lufthansa, Malaysia Airlines, Qantas, Singapore Airlines and Thai Airways International all using Rolls-Royce engines on their A380s. Along with Emirates (EK, Dubai Int'l), so far only Air France, Etihad Airways, Korean Air and Qatar Airways use Engine Alliance engines.
