Human Factors Analysis and Classification System (HFACS) is an accident investigation methodology. It is based on Reason model, the causality perspective commonly known as “Swiss Cheese” model. HFACS methodology became necessary because the Reason model is primarily descriptive, not analytical. It was designed to facilitate the application of this model to accident investigation and analysis. It was, specifically, developed to define the latent and active failures implicated in Reason model; and, refined through the analysis of hundreds of Aviation accident reports, containing thousands of human causal factors. The present work aims to evaluate the use of HFACS for the improvement of the Brazilian helicopter offshore transport industry safety performance. To do so, the present paper presents the Reason model, the HFACS and the HFACS-HE frameworks, considering evolution, limits, critical reviews, and applications (particularly, in Aviation). A documentary analysis of selected helicopter offshore transport industry accident reports from Brazil was carried out using HFACS-HE. Then, the study was compared with other studies already carried out for similar operations. It concludes that the causality model and culture frameworks have an impact on the application of HFACS, and on the safety performance.
