Engine Power Surge Halts Testing, Crews to Replace Engine
Boeing's new 787 Dreamliner took another ding last week as
one of its five test jets experienced an engine power surge on one
of its Rolls-Royce Group Plc engines before take off.
It's too soon to tell whether or not the test schedule will be
affected, Yvonne Leach, a company spokeswoman told Bloomberg
News.
The September 10 event occurred shortly before a flight in
Roswell, New Mexico, and the crew wasn’t in danger and the
surge was isolated to one engine, Leach explained.
According to Boeing's website, the Dreamliner test fleet has
completed 596 flights spanning more than 1,850 hours and is the
first jetliner to have more than 50 percent of the primary
structure - including the fuselage and wing - will be made of
composite materials.
Boeing selected General Electric and Rolls-Royce to develop
engines for the new airplane. Boeing says it is expected that
advances in engine technology will contribute as much as eight
percent of the increased efficiency of the new airplane,
representing a nearly two-generation jump in technology for the
middle of the market.

However, the Dreamliner's first delivery has been plagued with
complications and has been delayed six times in two years as Boeing
deals with new materials, parts shortages, redesign work and a
greater reliance on suppliers.
Aviation Week reports that tests on the replacement engine could
happen as early as Friday and if satisfactory, the work being done
at Roswell could resume the following day.
