The Boeing Co. (Everett, Wash.) announced April 7 that all test requirements were successfully met during ultimate load wing and fuselage bending tests, conducted March 28 on the 787 Dreamliner’s static test airframe. Applied wing loads replicated 150 percent of the most extreme forces the airplane is expected to experience while in service: The test unit’s wings were flexed upward approximately 25 ft/7.6m. The fuselage was pressurized to 150 percent of its maximum normal operating condition. “Successfully completing this test is a critical step in the certification of the 787, says Boeing Commercial Airplanes’ 878 program VP and general manager Scott Fancher. “This is further validation that the 787 performs as expected, even in the most extreme circumstances.”
