A door “blew off” a new Boeing 777X fuselage during a “load test” yesterday in Boeing hangar.
The incident happened during an ultimate load testing on one of the two 777X static test airplane, a standard final structural inspection procedure required ahead of first flights.
Plane was pressurized, under extreme load conditions on the ground, as FAA inspectors watched, door flew off.
The tests push the aircraft structure beyond its limits. Engineers pressurise the aircraft well beyond capacity and bent its wings in an extreme manner, to be certain that aircraft will withstand unlikely extreme conditions in the real world.
Following the incident, Boeing called off the tests, which will further the delay the first flight…
In a written statement to KOMO Newsradio, a Boeing spokesman said “…during ultimate load testing on the 777X static test airplane, an event occurred that forced the test team to halt testing. Safety is the highest priority at Boeing. The test team followed all safety protocols and there were no reported injuries. The team is currently working to understand what happened and ensure the area is safe for work to continue. The ultimate load test is the latest in a series of tests that Boeing has been conducting on this full-scale test airplane over the past several months.”
