Report an Aircraft Accident
Federal regulations require operators to notify the NTSB immediately of aviation accidents and certain incidents. An accident is defined as an occurrence associated with the operation of an aircraft that takes place between the time any person boards the aircraft with the intention of flight and all such persons have disembarked, and in which any person suffers death or serious injury, or in which the aircraft receives substantial damage. An incident is an occurrence other than an accident that affects or could affect the safety of operations.
Contact the Response Operations Center (ROC) at 844-373-9922 to file a report. A phone call is sufficient initially, but a written follow-up may be required.
