HUMAN FACTOR IN THE QUALITY IMPROVEMENT SYSTEM OF AIRCRAFT MAINTENANCE

Abstract

The subject matter of the article is the analyzes of the human factor in the quality improvement system of maintenance markers, which are aimed to evaluate the completeness of amount of work completed by the responsible party and technology of work performance as provided for by an engineering order, the goal is compare the results of the work of various operators and teams with established standards or against each other, for justification of measures aimed at quality improvement, evaluation of these measures effectiveness. On the basis of the purpose of the quality indicators and the methods for their determination, there are distinguished – initial quality evaluation, composite quality measures and overall quality level. Each type of maintenance quality evaluation has corresponding fields of application and calculation procedure. The methods used are semi-Markov processes with a finite set of states, a generalized structured method, the use of game theory, construction and analysis of cause and effect graphs, and situation assessment tree graph. Results. Taking into consideration the constant complication of aviation technique (AT), by means of new technologies introduction, new requirements are being put forward for the ground support personnel, and as the result, the price for aircraft failure has risen. That’s why, the reduction of failures amount through the fault of maintenance personnel due to the psychological characteristics of their activities is among the priority tasks with regards to flight safety. This goes to prove that the influence of the human factor on the quality and effectiveness of aircraft maintenance has not been fully studied in world wide aeronautical science. Conclusions. In general, the problem of improving the quality of professional activities of maintenance operators is complex and research should concern the entire aspect of the factors affecting its performance
