From Rolls-Royce press release:

The Rolls-Royce Trent 1000, launch engine for the Boeing 787 Dreamliner, has received its airworthiness certification on schedule and just 18 months after the engine’s first ground run.

It also maintains the 100 percent record of Rolls-Royce over the past two decades in achieving on-time certification for all aero engine development programs, including the previous four members of the market-leading Trent series.

The occasion was marked today by a special ceremony at Rolls-Royce in Derby, UK, at which the European Aviation Safety Agency (EASA) handed over the engine’s airworthiness certificate, which clears the Trent 1000 to power the Dreamliner’s first flight later this year.

The Trent 1000 made history by becoming the first engine to be validated concurrently by EASA and America’s Federal Aviation Administration (FAA) under the latest regulatory procedures.

Including business yet to be announced, orders have been placed for over 500 Trent 1000 engines by 15 operators and five leasing companies – approximately half the Boeing 787 customers who have made an engine decision. For more information about the Trent 1000, visit www.rolls-royce.com/trent1000.
