Boeing 777X will not be delayed by GE Aerospace's GE9X seal issue

GE Aerospace's Chief Financial Officer Rahul Ghai stated on Thursday that he is confident a?durability issue with GE9X engines'?mid-seal?"wouldn't hold up the entry into service of the Boeing 777X next year.

In February, the US company announced that it was examining a possible durability issue involving a'seal' in the GE9X. GE announced in April that it had 'identified the cause and was working on a solution.

Ghai, speaking at a Morgan Stanley Conference, said that testing had revealed the mid-seal?a part connecting 'the front and'rear sections of engine?was not as durable as GE expected.

He said that GE redesigned this part and began shipping GE9X engine fitted with the new sealing to Boeing in third quarter. The company anticipates FAA certification for the redesigned component in the coming months.

Ghai stated that GE was "extremely confident" about the redesigned'seal, after a series of internal tests. The design is now being incorporated into engines currently in production.

He said the existing seal could be used for the certifications that are in progress, as well as the approvals required before 'Boeing starts ETOPS testing. The FAA is certifying the redesigned seal for production aircraft.
