ROLLS-ROYCE ENGINE CERTIFICATED

7 August, 2007

                ROLLS-ROYCE TRENT 1000 FOR BOEING 787 RECEIVES        
                           `TICKET TO FLY' ON 7/8/7                            

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 per cent record of Rolls-Royce over the past two
decades in achieving on-time certification for all aero engine development
programmes, including the previous four members of the market-leading Trent
series.

The occasion was marked today (07.08.07) 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.

Mike Terrett, President - Civil Aerospace, told an audience of 300 employees:
"The Trent 1000 continues to set the pace on the 787 programme - first engine
to run and first to be certified. Going forward, it will be first to fly on the
787 and first to take the Dreamliner into service.

"This is another proud moment for everyone who watched our engine sharing the
spotlight at the 787's recent Premiere in Seattle. It is an important day, not
only for the team at Rolls-Royce, but also for our colleagues at Boeing, our
programme partners, suppliers, and, of course, our customers.

"Focus now turns to the first flight of the 787, and beyond that, to ensuring a
smooth entry into service with launch customer ANA (All Nippon Airways) when
they begin commercial flights next year."

Mike Bair, Vice President and General Manager of the Dreamliner programme, told
Boeing employees at a parallel event in Seattle: "Three years ago the joint
Boeing and Rolls-Royce team got together and laid out a programme from first
test run to engine certification. Through your hard work and dedication you
have found a way to achieve those critical milestones on time. It brings us one
step closer to the day we're all eager for - the Dreamliner's first flight."

Nine development engines have been used in ground testing, and a further ten
will support flight testing on four 787s. Delivery of production engines to
Boeing will begin in the first quarter of next year.

Design of the Trent 1000 has focused on delivering world-best levels of fuel
burn, noise and emissions. The continuing introduction of new technology,
supported by the experience of Trent series engines already in service, will
ensure that the Trent 1000 delivers the lowest emissions for the 787, exceeding
the requirements of current and future legislation.
