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.
