What is the primary role of the NTSB in aviation safety?

• A. Lead agency in post-accident investigation
• B. Regulates air traffic control
• C. Sets pilot licensing standards
• D. Oversees airport security

Answer: (A)

The core idea is that the NTSB leads independent post-accident investigations and issues safety recommendations to prevent recurrence. After an aviation incident, the NTSB conducts a thorough investigation to determine the probable cause, documents findings, and identifies contributing factors. It then issues safety recommendations aimed at regulators, manufacturers, and operators to improve future safety. This agency does not regulate or certify aviation activities—that role belongs to the FAA—nor does it oversee security screening or air traffic control responsibilities, which are handled by TSA and the FAA respectively. Therefore, the primary role is conducting post-accident investigations and driving safety improvements through recommendations.
