Seattle, Washington - Boeing announced that it temporarily halted the tests with the 777X after the engineering team met an unexpected issue.
A door blew during the final payload testing that must be approved as part of the aircraft’s airworthiness certification by the Federal Aviation Administration (FAA).
Final load tests are carried out to determine the loads and stresses beyond normal operational loads.
During final load testing on the 777X static test airplane, the team encountered an issue that required suspension of the test,
a Boeing spokesman said.
It's not known if the issue will cause further delays in the program. It will be cleared up after careful analysis to find out the root cause of the failure.
Boeing's 777X program is already pushed back because of a technical problem found on the General electric's GE-9X engines that will power the aircraft.
The aircraft was intended to make its first flight in June this year, but it was postponed until next year.
This ground test failure is now another setback in the program schedule.
The Boeing 777X is the largest twin-engine widebody jet ever produced for commercial use.
