Background ✨
GE Aerospace CFO Rahul Ghai said GE commenced shipping GE9X engines fitted with the redesigned mid-seal to Boeing in 3Q2026, and it expected US FAA certification of the part in the coming months, while maintaining the issue would not affect the Boeing 777X's planned 2027 entry into service.1 Boeing said FAA approval to begin 777-9 ETOPS flight tests remained on hold pending completion of the mid-seal certification plan, potentially affecting 2026 certification testing.2
