Difficulties experienced by accident investigators in explaining what happened and why it happened in specific accident investigations are examined. These include problems with delineating the beginning and end of the accident, methods for discovering and testing the relevance of facts of the accident, and methods for presenting the findings of the investigation. Criteria for approaches to resolve these difficulties are suggested. Concepts influencing current methods of research and investigations are discussed, along with their limitations in terms of the suggested criteria. A generalized explanation for the accident phenomenon based on the role of perturbation in an events sequence (P-theory) is proposed, and a charting method for ordering the events of a particular accident is presented. Development of an events indexing system for future accident data collection is suggested.
