GE9X mid-seal problem holding up Boeing’s 777-9 ETOPS approval

A critical issue with the mid-seal of GE Aerospace's GE9X turbofan is currently preventing Boeing from securing FAA certification for its ETOPS flight-test program. This problem directly impacts Boeing’s efforts to obtain extended-range approval for the 777-9, a key step in completing the long-delayed aircraft project. Kelly Ortberg, Boeing CEO, maintains that the company remains focused on resolving this matter swiftly. The delay has significantly disrupted Boeing’s timeline for delivering the 777-9 and achieving final production completion. Until the fix certification plan is approved by the FAA, further progress on the 777-9’s operational authorization will be stalled.
