What is the primary role of the National Transportation Safety Board (NTSB)?

The primary role of the National Transportation Safety Board (NTSB) is to investigate and determine the probable cause of transportation accidents, including aircraft incidents and accidents. This involves a comprehensive review of various factors surrounding an incident, such as mechanical failures, human error, and environmental conditions. By conducting thorough investigations, the NTSB aims to improve safety in the transportation sector by making recommendations to various stakeholders, including regulatory agencies, industry groups, and the public.

While other options relate to important aspects of aviation and transportation, they do not represent the central focus of the NTSB. For instance, enforcing aviation regulations is primarily the responsibility of the Federal Aviation Administration (FAA). Managing the air traffic control system is also under the jurisdiction of the FAA, which oversees the safe and efficient movement of aircraft through the national airspace. Additionally, providing training for flight crews is typically handled by airlines and training organizations, rather than the NTSB. Thus, the investigation and review of aircraft incidents and accidents distinctly capture the essence of the NTSB’s mission.
