Headquarters and Field Offices exist for several services including accident investigation and prevention, air traffic oversight, flight standards (certificate management and civil aviation registry), and aircraft maintenance. NTSB is short for National Transportation Safety Board. NTSB traces back to the Air Commerce Act of 1926, however, NTSB was not created until the 1967 as the federal government's primary accident investigation agency for all modes of transportation including aviation, highway, railway, marine, and pipeline. The NTSB is an independent United States government investigative agency responsible for civil transportation accident investigation. The main responsibility of the NTSB is to investigate and report on aviation accidents and incidents, certain types of highway accidents, ships and marine accidents, pipeline incidents, and railroad accidents. The NTSB is not subordinate to any

government agency, and it does not possess regulatory or rulemaking powers. Rather, the NTSB works with governmental agencies (FAA, DoD) and civil organizations through the party process to conduct accident investigation. The primary goal is to determine probable cause(s) and provide safety recommendations to FAA and civil aviation organizations. 2. Explain and define how “modeling” and/or applying the HFACs matrix can improve aviation safety in a proactive manner. The Human Factors Analysis and Classification System (HFACS) is a broad human error framework that was developed to further define the “active” and “latent” failures in a productive system for use in accident investigation and analysis. Its roots are heavily based on James Reason’s “Swiss Cheese” model for accident causation. The HFACS framework includes four levels based on Reason’s model, but in greater detail: unsafe acts, preconditions for unsafe acts, unsafe supervision, and organizational influence. The approach of HFACS is to take a system-based view wherein the human is not the sole contributor to an accident, or in different terms, the error is a result of a larger failure in the organization. The systemic approach is the key to using HFACS to analyze an accident and find links in the error chain that, if removed, can prevent future accidents. The ultimate goal of an organization is to prevent the accident at the earliest possible level, setting barriers at each (organizational, supervisory, and preconditions) level before reaching the unsafe act. Using HFACS to classify human error typically begins with level 1, the unsafe act. It then can be used to work backwards up the chain - identify preconditions, unsafe supervision, and organizational influences.
