SEATTLE, Jan 16 (Reuters) – Boeing resumed testing for its long-delayed 777X widebody jet on Thursday, with the first flight since the U.S. planemaker grounded the test fleet in August due to the failure of a key engine mounting structure.
The grounding came just five weeks after it had started certification flights for the 777-9 with officials from the U.S. aviation regulator onboard.
Federal Aviation Administration staff were not on board for Thursday’s flight, according to the company.
Boeing first planned to deliver 777X in 2020, now slated for 2026.
