Risk and reliability analysis of the boeing 737 fleet

Abstract

[ES] Aviation safety is at the core of the fundamental Objectives of the entire air transport community. They are constantly striving to further improve aviation’s successful safety performance while maintaining a high level of capacity and efficiency. Even though accidents cannot be predicted, it is important to have knowledge about the risks that aircrafts have to face on the ground and during the flight to create these strategies, and how to act in case of accident. The purpose of this is project is to perform a statistical analysis on risk and reliability of a family of aircrafts from the so popular Boeing Company: the 737 fleet. The project is going to be divided into three main parts. First, an introduction to the project containing the following: a historical review of the evolution of the fleet with the characteristics of each aircraft series, and the definitions of the main aviation concepts that will be used for future calculations. The second part is a deep analysis of the database with the accidents that happened between years 2002 and 2017, separated in different categories: number of fatalities, aircraft series, lifetime until accident, phase of flight during which it happened and undesirable event that led to it. To finish up, the third part includes the main risk analysis with the calculation of the probabilities for each kind of accident and the conclusions achieved.
