Boeing is facing sanctions from the National Transportation Safety Board (NTSB) for sharing unauthorized information about a door plug blowout on a 737 Max 9.

The NTSB criticized Boeing for violating investigative regulations and speculating on the incident's causes.

Boeing now faces restrictions on accessing ongoing investigation materials and a subpoena for an investigative hearing.

The Justice Department is also considering potential charges against Boeing for previous safety issues.

CEO David Calhoun, who plans to step down by the end of 2024, defended the company's safety record amidst the scrutiny.

Prosecutors are expected to make a decision on potential charges against Boeing by July 7.

The Skift Travel 200 index is closely monitoring the situation.
