Reliability Analysis of Components in Aviation: A Practical Application

This presentation shows, within civil aviation, a framework concerning component reliability as a strategy to fulfill all national and international authorities’ requirements. Based on reliability principles and theory, a methodology was followed for a particular and suggested component, adjusting some distributions to the most important failure modes and determining their parameters. Using specific times to failure (Time Since New - TSN) and censored data, the results achieved allow us to understand the behaviours of each failure mode, the values for reliability at a particular flight time and expected failure rates, as well as other information suitable for treatment. To deal with uncertainties, confidence intervals were considered.
