Faxing to National Transportation Safety Board — FAQ

National Transportation Safety Board does not publish one fax for the whole agency. The line for the docket or secretary's office is separate from the one for your case office. Ask for the office you actually need to get the right number. Which line is right depends on the office, not the agency as a whole.

Include the identifiers National Transportation Safety Board uses to match your record: name and case or file number. Direct the cover sheet to the correct National Transportation Safety Board office and include a number staff can call. That routing detail is what lets National Transportation Safety Board reconnect the documents if they separate. Complete, legible identifiers are what move the request fastest.

For some documents, yes; for others, National Transportation Safety Board wants an online submission. Where a portal covers your request, it is usually faster than a fax. Ask the office directly so you do not send to a line that is no longer used.
