A simple method of estimating the maintenance cost of airframes

Abstract

Purpose

To make easier the estimation of maintenance cost of airframes, using commercial software and considering reliability's conditions.

Design/methodology/approach

It was possible to propose a new method using commercial reliability software. Stress load is included as a random variable in reliability analysis. An example is done. The results are compared with other works.

Findings

It is easier and faster to apply than the methodology proposed by other authors.

Originality/value

This paper suggests an easy way of evaluating the economic life of aircraft structures. The calculated optimal stress distribution function can be used with commercial reliability software to estimate the crack size population.
