A case study of fishbone sequential diagram application and ADREP taxonomy codification in conventional ATM incident investigation. Symmetry, 2019, Volume 11, Issue 4, Article number 4912073-8994https://doi.org/10.3390/sym11040491https://dspace.lib.cranfield.ac.uk/handle/1826/14126This paper aims to present the application of a fishbone sequential diagram in air traffic management (ATM) incident investigations performing as a key connection between safety occurrence analysis methodology (SOAM) and accident/incident data reporting (ADREP) approaches. SOAM analysis is focused on organizational cause detection; nevertheless, this detection of individual causes from a complete incident scenario presents a complex analysis, and even more, the chronological relationship between causes, which is lacking in SOAM, should be tracked for post-investigation analysis. The conventional fishbone diagram is useful for failure cause classification; however, we consider that this technique can also show its potential to establish temporal dependencies between causes, which are categorized and registered with ADREP taxonomy for future database creation. A loss of separation incident that occurred in the Edmonton area (Canada) is used as a case study to illustrate this methodology as well as the whole analysis process.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/ATM incident analysisfishbone sequential diagramADREP taxonomySOAMArticle
