Boeing has grounded its fleet of 777X test aircraft after a routine inspection revealed damage to a key structure on one of the planes. The issue was found during scheduled maintenance on a part that connects the engine to the main body of the aircraft. In a statement, Boeing said, “Our team is replacing the part and capturing any learnings from the component and will resume flight testing when ready.” The company has informed the Federal Aviation Administration and its customers about the situation.
The 777X, which is set to be the world’s largest twin-engine jet, has faced multiple delays. It was originally scheduled to enter service in 2020, but that timeline has been pushed back to 2025.
Boeing pauses 777X testing activities
This latest setback comes as Boeing is working to overcome a series of challenges, including a safety crisis involving its 737 Max aircraft. In January, a door plug blew out on an Alaska Airlines 737 Max during a flight. The extent of the impact on the 777X’s certification and delivery schedule is not yet clear.
Boeing began certification testing with the FAA in July, which was a significant step forward in the plane’s development. The company said it will provide updates as it continues to address the issue and work towards getting the 777X back in the air for testing. The 777X has 481 orders from customers around the world.
