Key Takeaways:

Boeing has developed and implemented a fix for cracked engine thrust links on its 777X aircraft, which had paused testing last year due to unintentional vibration.
The solution involves installing new, redesigned thrust links and making engineering adjustments to prevent future vibratory responses, with changes already in test aircraft and further improvements planned for production models.
This resolution addresses one of several setbacks for the 777X, a program now projected to begin deliveries next year and enter service by 2026, six years behind its original schedule.

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.
