Key Takeaways:

Boeing has developed and implemented a fix for the cracked engine thrust links on its 777X, which caused a pause in testing last year due to unintentional vibration.
The solution involves redesigned thrust links and adjustments to prevent vibration, already applied to flight test aircraft with further improvements planned for production models.
The 777X program has experienced numerous setbacks, running six years behind its original schedule due to various issues.
Boeing is targeting 777X certification for late 2025 or early 2026, with deliveries expected to begin next year.

Boeing says it has developed a fix for a component problem that temporarily paused testing of its 777X last year.

The company said it is installing new, redesigned engine thrust links, which transfer thrust from the engine to the aircraft structure. Cracks in the original thrust links forced Boeing to suspend testing of the 777-9 in August 2024, as the aircraft was undergoing certification.
