GE Aerospace Just Solved Its Biggest Boeing 777X Engine Problem With 1 Redesign

The all-new Boeing 777X is known in the aviation community for a few keystone features not seen on its predecessors in the Boeing 777-300ER or -200 variants. The folding wingtips, the composite span, and Boeing’s certification backlog have made headlines regularly with respect to the changes to the 777 program. While these characteristics have their own set of engineering challenges, there is a key component inside the prescribed engine, the appropriately named General Electric GE9X, that has been changing the certification timeline upon testing completion.
