Abstract

Aircrafts maintenance is a major and complex activity with aiming to achieve high standards of safety 
and attain an increased level of reliability of system at the lowest possible cost. therefore, estimation of 
failures risk of aircrafts has become necessary. The paper aimed for estimating failures risk in order to 
determine an optimal time for starting in the maintenance activities using Fault Tree Analysis (FTA) 
approach. The FTA approach uses scenarios to identify a critical equipment that can effect on the 
operating performance the aircrafts. Based on the estimated risk scenarios that extracted through 
maintenance records of aircrafts, the results showed that FTA approach has able to estimate the failures 
risk for any critical equipment run under different environmental conditions.
