What role does the NTSB play in aviation?

The NTSB, or National Transportation Safety Board, plays a crucial role in aviation by investigating transportation accidents and promoting safety. This agency is responsible for conducting thorough investigations into aviation accidents, determining their probable causes, and making recommendations to prevent future incidents. The emphasis on investigation includes gathering evidence, analyzing technical data, and interviewing witnesses, which ultimately contributes to enhancing safety across the aviation industry.

Through its findings, the NTSB issues reports and safety recommendations aimed at improving operational practices, aircraft design, and regulatory policies. This kind of oversight is crucial in shaping the standards and protocols followed by airlines, pilots, and maintenance personnel, ensuring that the aviation sector continuously strives for higher safety levels.

The other options refer to responsibilities that fall outside the NTSB's jurisdiction. Regulating air traffic procedures is typically under the purview of the FAA (Federal Aviation Administration), while pilot training and certification is also managed by the FAA. Aircraft manufacturing licenses are issued based on regulations established by the FAA as well, demonstrating that the NTSB focuses specifically on investigations and safety advocacy rather than regulatory or training functions.
