December 28, 2010 - Boeing began resume flight test
activities on the 787 Dreamliner after suspending flight
test last month following an in-flight electrical
incident on a test flight in
Boeing has installed an interim version of updated power
distribution system software and conducted a rigorous
set of reviews to confirm the flight readiness of ZA004,
the first of the six flight test airplanes that will
return to flight.
"Initially, we will resume a series of Boeing tests that remain to be completed in the flight test program. That testing will be followed later by a resumption of certification testing," said Scott Fancher, vice president and general manager of the 787 program. |

Testing
included an intentional deployment of the Ram Air Turbine (RAT),
which is a small turbine that is deployed when back-up power is
required. Boeing and Hamilton Sundstrand completed testing of
the interim software updates earlier this week. Verification of
the system included laboratory testing of standalone components,
integration testing with other systems, flight simulator testing
and ground-based testing on a flight test airplane.
In the
last several weeks, the company continued ground testing as part
of the certification program. Additional ground testing will be
done by the company on the production version of the airplane to
further verify performance of the changes being made.
