Boeing stops test flights of wide-body 777X aircraft due to error

AFP news agency on August 21 quoted a statement from Boeing (USA) saying that flight testing of the 777X wide-body aircraft model had just been suspended after discovering an error connecting the engine to the fuselage.

"During scheduled maintenance, we identified a component that was not performing as designed. Our team is replacing the component, documenting any associated issues, and will resume flight testing when ready," the statement said.

Boeing has faced repeated safety and quality control concerns in recent years, including the door failure on an Alaska Airlines Boeing 737 MAX in January that added to the pressure on the company.

Boeing orders unexpectedly outstrip Airbus in July

Boeing's 777X wide-body program, announced in November 2013, is the latest addition to the company's popular 777 family.

The new twin-aisle aircraft is set to be the world's largest twin-engine jetliner. More than 500 777Xs have been ordered, but they have yet to enter commercial service.

Boeing said the part that led to the flight test suspension is specifically designed for the 777-9 and connects the engine to the aircraft structure. The new plane will come in three models: the 777-8, the 777-9 and the 777-8 freighter.

Other 777-9s used for testing are currently undergoing inspections following the incident, Boeing said. The aircraft's entry into service was originally scheduled for 2020, but has now been delayed until 2025 due to certification issues.

Although the 777X has yet to receive approval from the US Federal Aviation Administration (FAA), Boeing passed a major milestone in July. After a large number of test flights, the company was allowed to begin testing the 777-9 in the presence of FAA representatives.
