Root Cause Analysis Methods for The Design of Aviation Parts

Abstract

Fault modes, which aren’t detected throughout the design phase if they are not defined with precautions have the crucial potential on the quality of mature products. At first glance, the impression of the quality failures may be underestimated, before the design of aviation parts are implemented to production. But these failures may cause some problems in aviation safety and reliability. Therefore, the failures during the project phase should be investigated by root cause analysis and defining the precautions both increase effectiveness of design and quality of the outputs. The aim of this study is, emphasizing the importance of root cause analysis on the design of aviation parts, and stating the analysis methods, which have been used mainly. In the scope of this effort, aviation regulations are researched which encourages the root cause analysis accordingly, related methods are evaluated for the resolutions. The common methods are classified based on the hazard review of the failures and explained to point out for the researchers.
