GE Aerospace fixes 777X engine issue on schedule

GE Aerospace said a durability issue found in its GE9X engine will not affect the planned entry into service of the Boeing 777X aircraft next year. The company shared the update on Thursday, 18 September, during a Morgan Stanley conference.

The problem involved the mid-seal, a part connecting the front and rear sections of the GE9X engine. After testing revealed that the original design fell short of durability targets, GE Aerospace engineered an updated component. The manufacturer incorporated the redesigned piece into production and began shipping updated engines to Boeing in the third quarter. GE Aerospace expects certification from the Federal Aviation Administration within the next few months.

GE Aerospace first disclosed the potential issue in February and later identified the root cause. Internal testing confirmed the durability of the redesigned seal, allowing the company to maintain the GE9X schedule.

Separately, GE Aerospace addressed its recently agreed $11.75 billion acquisition of Consolidated Precision Products. The company explained that the deal aims to secure supplies of precision-cast engine components rather than signal a broader push into vertical integration.
