Page "National Transportation Safety Board" Paragraph 6

An investigation of a major accident within the United States typically starts with the creation of a " go team ", composed of specialists in fields relating to the occurrence.

This is followed by the designation of other organizations or corporations as parties to the investigation.

The Board may then choose to hold public hearings on the issue.

Ultimately, it will publish a final report and may issue safety recommendations.

The Board has no legal authority to implement, or impose, its recommendations.

That burden falls upon regulators at either the federal or state level or individual transportation companies.
