Boeing’s next-generation widebody aircraft, the 777X, is encountering further difficulties as its test fleet has been grounded. The aircraft, already delayed by several years, faces new setbacks after cracks were discovered in a critical component.
According to a report by The Air Current, a Boeing 777-9 test plane was found to have "cracks in the thrust link structure" following a flight to Kona. Additionally, issues with the engine mounting have been identified on two other 777-9 test planes.
The thrust link structure plays a crucial role in transferring thrust loads from the engine to the aft lower engine mount. Although designed to carry the engine even if one thrust link fails, this component's unique design is not shared with other currently operational aircraft. The engines of the 777X are notably larger and heavier compared to those on existing Boeing models.
