GE Aerospace says GE9X mid-seal issue won't delay 777X service entry

• GE Aerospace started shipping GE9X engines with redesigned mid-seals to Boeing in Q3
• FAA certification of the redesigned mid-seal component is expected in the next few months
• The mid-seal durability issue is not expected to impact the Boeing 777X's 2024 service entry timeline

GE Aerospace GE9X Engine Issue Won't Delay Boeing 777X Service Entry

Key Developments:

GE Aerospace CFO Rahul Ghai confirmed on Thursday that a durability issue affecting the GE9X engine's mid-seal component will not delay the Boeing 777X's planned entry into service in 2024. Speaking at a Morgan Stanley conference on September 17, Ghai expressed confidence in the resolution timeline.

Technical Resolution:

• GE Aerospace began shipping GE9X engines with redesigned mid-seals to Boeing in Q3 2023
• FAA certification for the redesigned part is expected within the next few months
• The mid-seal durability issue has been addressed through engineering modifications

Companies Involved:

• GE Aerospace: Engine manufacturer addressing the technical issue
• Boeing: Aircraft manufacturer awaiting engines for the 777X program
• FAA: Regulatory body overseeing certification of the redesigned component

Market Implications:

This announcement provides reassurance to both companies' stakeholders that the 777X program remains on track despite technical challenges. The GE9X engine, the world's most powerful jet engine, is exclusively designed for Boeing's 777X widebody aircraft. Any delays to the 777X program would have significant financial implications for both GE Aerospace and Boeing, affecting delivery schedules and revenue recognition.

The timely resolution of this technical issue is critical for Boeing, which has faced multiple delays with the 777X program over recent years. GE Aerospace's proactive approach in redesigning and shipping the improved mid-seals demonstrates commitment to meeting the service entry timeline, supporting investor confidence in both companies' execution capabilities for this flagship widebody aircraft program.
