EVERETT, Wash., Sept. 27 /PRNewswire-FirstCall/ — Boeing (NYSE: BA)
successfully completed a high-pressure test, known as “high blow,” on the
787 Dreamliner static test airframe at its Everett factory today. The test
is one of three static tests that must be cleared prior to first flight.

During the test, the airframe reached an internal pressure of 150
percent of the maximum levels expected to be seen in service — 14.9 lbs.
per square inch (1.05 kilograms per centimeter) gauge (psig). It took
nearly two hours to complete the test, as pressure was slowly increased to
ensure the integrity of the airplane.

“We had every confidence going into this test because of the extensive
work we’ve done on larger and larger pieces of composite — from small
coupons to fuselage sections,” said Pat Shanahan, vice president and
general manager of the 787 program. “Still, it’s very rewarding to see a
whole airplane being tested and having the results we expected.

“I am so proud of the team that has worked on this program and the
progress we are making.”
