Boeing 777X Returns to the Skies After August Grounding
Boeing restarts 777X test flights after engine structure failure halted operations, pushing the jet’s first delivery to 2026 amid rigorous testing efforts.
Boeing has resumed test flights for its 777X widebody jet after halting operations in August due to a critical engine mounting structure failure. The latest flight marked a significant step in the aircraft’s development, as the 777-9 test plane flew between Seattle and Moses Lake, Washington.
The 777X program has faced multiple delays, with its first delivery now slated for 2026, six years after the original target. The aircraft family includes the flagship 777-9, the smaller 777-8, and a freighter version expected later in the decade. Boeing’s 777X is designed as a successor to the popular 777, boasting improved fuel efficiency and advanced aerodynamics.
The planemaker has received 481 orders for the 777X, with major commitments from carriers such as Emirates, Qatar Airways, Lufthansa, Singapore Airlines, and Cathay Pacific. Emirates leads with 170 orders, while Qatar Airways has 60.
During the resumed testing, Federal Aviation Administration (FAA) officials were not onboard. Boeing emphasized its commitment to rigorous testing to ensure the safety, performance, and reliability of the aircraft. Details of the flight performance remain undisclosed, as Boeing declined to comment further.
