FAA asks for action plan to be submitted within 90 days after Boeing accident. In January, the window panel of a Boeing passenger plane was blown off over the western state of Oregon in the United States.

The FAA has not approved the expansion of production of the 737 MAX passenger plane, and is considering using an independent third-party organization to oversee Boeing's inspection and quality systems. We have announced that we will compile measures to strengthen supervision within the next week, the FAA said in a statement.
