Investigation Reports

Accident Reports are one of the main products of an NTSB investigation. Reports provide details about the accident, analysis of the factual data, conclusions and the probable cause of the accident, and the related safety recommendations. Most reports focus on a single accident, though the NTSB also produces reports addressing issues common to a set of similar accidents.
