AMSMA (Aviation Maintenance Safety Management Assistant) An Alternative Top-Down Approach to Support Risk Management and Decision-Making

Abstract

Most incident or accident investigation approaches aim at preventing the same causal pattern to occur again in the future. However, causal attribution is often the subjective application of the analyst's safety model(s) to an event rather than an explicit shared safety model. This easily leads to self-fulfilling prophecies. In order to reach beyond existing limitations, an original approach has been developed in aviation. It is intended to facilitate the extraction of general "safety lessons" from reported events and to support safety-related Decision-Making.
