Risk and reliability analysis based on airbus a319/320/321 fleet

Abstract

[EN] Accidents are results of a sum of mishaps and unfortunate occurrences, and are defined as occurrences associated with the operation of an aircraft which takes place between the time any person boards the aircraft with the intention of flight until all such persons have disembarked. We cannot know when are they going to happen, so we should be prepared for actuating correctly for these. In this project, we are going to make an estimation of the probabilities and the risk of accident focusing in one aircraft, the Airbus 320 family, which includes A318, A319, A320 and A321. We have divided it into four parts. The first part includes an introduction and a brief description of the Airbus company, and some specifications of each aircraft of the family with some main differences among them. The second part is a definitions section, in which we explain what is an accident and some key words to understand the project, and some concepts like definitions of phases of flight, undesirable events, natures of flight, categories of flight and airplane damages. The third part consist of an analysis of the database we have selected to study, also the analysis of an Airbus report of accidents between years 1958 and 2014, comparing the results of each range of dates. The last part consists on the calculation part, in which we obtain the probabilities of each accident occurred, the measure of the risk and the conclusions.
