Which organization investigates aviation accidents to determine causes and prevent recurrence?

• A. FAA
• B. NASA
• C. NTSB (National Transportation Safety Board)
• D. NTSR

Answer: (C)

When looking for who investigates aviation accidents to determine causes and prevent recurrence, the National Transportation Safety Board is the one responsible. This independent federal agency specializes in examining transportation accidents, including aviation, to identify probable causes and issue safety recommendations aimed at preventing similar events in the future. The FAA focuses on safety regulation, certification, and airspace management, not the formal accident investigations. NASA does safety-related research and may study incidents to learn from them, but it isn’t the primary accident investigator for civil aviation. NTSR isn’t an active organization in this context. So the best answer is the National Transportation Safety Board.
