Boeing announced it is stopping test flights of its 777X aircraft, which is still under development, after a structural problem was found during a routine post-flight inspection.

In a statement to YSL News, Boeing explained, “During routine maintenance, we detected a component that did not function as intended. Our team is in the process of replacing this part and learning from the situation before we resume flight tests.”

The issue and the decision to suspend flights were initially reported by The Air Current.

Boeing clarified that the problematic part is a structural element located between the engine and the airplane structure. The company is currently examining the entire 777X test fleet for similar issues and has no immediate plans for additional test flights.

It’s important to note that this component is specific to the 777-9 model, meaning that operations of other aircraft in service will not be impacted.

After The Air Current’s findings, many in the aviation community took to social media to highlight that such test flights are essential for detecting potential problems prior to commercial operation. This setback, while inconvenient for Boeing’s already delayed 777X program, reflects that the testing process is functioning as it should.

Boeing’s safety standards have faced scrutiny lately, especially after a door malfunction occurred on an Alaska Airlines 737 Max in January. The company claims it is implementing changes to enhance safety.
