Boeing’s 777X aircraft, a delayed program and a successor to the successful 777 aircraft, has been found to have a failure in one of its structures. This program has already been delayed to receive certification by the end of 2025 and be launched in 2026. 

Now, the test flights for program 777X have been stopped because the structure that attaches the engine to the wings has failed or broken as revealed during the thorough checking. After the test flight, the plane was thoroughly checked during which a crack was found in the part which is responsible for the proper working of the engine. The flights of the 777X program will be resumed once the crack is fixed. 

Boeing has stated to inform the public that the team is working to know the potential reasons for this problem and fix it as early as possible to resume the test flights. The company further added that the part cracked was only used in the 777X model and not in other planes. Furthermore, they ensured that the Federal Aviation Association has been updated about the issue and will continue to receive information about the ongoing process. 

According to the reports, before the problem was found in the plane it completed the flight from Hawaii which was approximately 6 hours long. 
The aircraft 777X, according to the company, is designed in a way that is more fuel efficient and has the potential to provide extra comfort to passengers. The public was expecting its launch in 2020, however, certain issues have put its launch to a halt till now. But the company is hopeful that by 2026 it will enter to service.
