Boeing announced on Monday that it has temporarily halted flight tests of its 777X aircraft after discovering structural damage in one of the wide-body jets. The damage was found in a custom part located between the engine and the airplane’s structure during routine scheduled maintenance. In response, Boeing grounded the three other 777-9 airplanes in its test fleet, though the company noted that no additional flight tests were planned for those aircraft at the time.
Boeing issued a statement indicating that its team is in the process of replacing the damaged part and analyzing the component to understand the cause of the issue. “Our team is replacing the part and capturing any learnings from the component and will resume flight testing when ready,” the company said. Boeing has also informed the Federal Aviation Administration (FAA) and its customers about the situation. The 777X program has garnered significant interest, with 481 orders for the aircraft according to Boeing’s website.
The potential impact of this grounding on the 777X’s certification and delivery schedule remains uncertain. The new wide-body jetliners are currently slated for delivery in 2025, which is already about five years behind the original schedule. Boeing began flight tests of the 777X with the FAA in July, marking a major milestone in the aircraft’s development. Any further delays could add additional pressure to Boeing as it works to meet its commitments to customers.
This development comes as Boeing’s leadership, including newly appointed CEO Kelly Ortberg, is striving to guide the company through a challenging period. Earlier this year, Boeing faced a safety crisis following a door plug blowout incident, which underscored ongoing challenges within the company’s production and safety processes.
The 777X program has been closely watched by the aviation industry, as it represents a significant advancement in Boeing’s wide-body aircraft offerings. The aircraft is designed to offer greater fuel efficiency, range, and passenger capacity, making it a key component of Boeing’s strategy to compete in the long-haul international market.
As Boeing addresses the structural damage and prepares to resume flight testing, the aviation community will be closely monitoring how these developments impact the 777X’s path to certification and its eventual entry into service. The outcome of these efforts will be critical in determining Boeing’s ability to deliver on its promises to customers and maintain its competitive position in the global aerospace market.
