A tire of a United Airlines Boeing 777-200 aircraft fell off shortly after taking off from San Francisco International Airport. Industry insiders told reporters that the above-mentioned accident was probably caused by improper maintenance.

In January, a Boeing 737 MAX 9 operated by Alaska Airlines made an emergency return to Portland International Airport after its built-in emergency door fell off. In February, the Federal Aviation Administration asked Boeing to develop a comprehensive action plan within 90 days to resolve "systemic quality control issues"
