RESUMO

Considering the actual technology available, an issue became crucial: to determine for how much time a critical device will be capable to perform, without failures, its function. When the operation of this device inlays a raised risk, as it occurs in aviation, reliability is distinguished of the others dimensions of the quality, therefore the occurrence of failures can result in the loss of human lives and in damages to properties or to the environment. Under this perspective, the current work presents some basic concepts of reliability engineering, applied to the maintenance of aviation fleet, considering the characteristics of project, homologation set of laws, and analyzing the possibilities of performance when compared to specifications. This study has as objective to analyze the reliability of aeronautical component, during the respective life cycle of an aircraft mechanical component, aiming at costs reduction and accident prevention. Therefore, a revision of the basic literature, focused on aircraft maintenance was realized, balancing consecrated theory with current articles and thesis of varied areas of application of the reliability engineering. It was used a complementary view of the qualitative and quantitative approaches, to analyze the performance of one specific mechanical component, chosen by its actual reliability, inconsistent with its specifications. In the first data collection, its reliability was measured and than, procedures to improve maintenance quality were defined. The effectiveness of the adopted procedures was measured. The second data collection allowed to diagnosis an improvement in the performance of the component, although not being possible the quantification of such improvement, because of the necessary changes on data status.
