Who is responsible for conducting civil aviation accident investigations in the U.S.?

• A. FAA
• B. DOT
• C. NTSB
• D. Local law enforcement

Answer: (C)

The National Transportation Safety Board (NTSB) is the entity primarily responsible for conducting civil aviation accident investigations in the United States. The NTSB operates independently and is dedicated to investigating transportation accidents across various modes, including aviation. Their role includes determining the probable cause of accidents, making safety recommendations to prevent future occurrences, and advocating for improvements in transportation safety.

The NTSB collects evidence, interviews witnesses, and analyzes data to piece together what led to an accident. This comprehensive approach allows them to fulfill their mission of enhancing safety within the aviation industry. Their findings can have significant implications for procedural changes and regulatory adjustments in aviation operations.

In contrast, other options play different roles within the aviation framework. The Federal Aviation Administration (FAA) primarily regulates and oversees aviation safety through regulations but does not conduct investigations. The Department of Transportation (DOT) manages national transportation policy and infrastructure but does not focus on accident investigations per se. Local law enforcement may assist at the scene of an accident but does not have jurisdiction over the investigation itself. This distinction underscores why the NTSB is the correct answer for this question.
