CORRECTION OF NORMS OF SPARE PARTS EXPENSES WHEN TRANSFERRING TO CONDITION-BASED MAINTENANCE OF AIRCRAFT

Abstract

The article suggests a methodological approach to adjusting the cost norms of spare parts for the exploitation of aviation equipment when transferring it to operation by technical condition. Correction of cost norms is done to clarify the required nomenclature of spare parts in accordance with the expected need for operation by the technical condition of aviation equipment. To determine the required number of spare parts the distribution of aviation equipment by operating methods is used. The distribution of products by methods of technical operation includes 2 levels. On the first level, all possible types of failures of functional systems are analyzed and their consequences are evaluated. The need for scheduled control of working capacity as a whole in maintenance is being established. On the second level, the reasons for failures of functional systems are analyzed - possible abandonment of elements. Depending on their consequences and characteristics of the reliability of each of the elements, the categories of importance of object failures are established. The choice of methods of operation of products is defined. The requirements for ensuring the normative level of flights safety and the combat of aviation parts, as well as ensuring the economic efficiency of work on the control of the technical condition of the aircraft products are considered.

The application of the proposed methodological approach will allow correction of the cost norms of spare parts for the operation of the aviation equipment of state aviation of Ukraine when putting it into operation according to the technical condition, to reduce operating costs by reducing the needs of products that can be put into operation by methods maintenance untill failure and to pre-failure state, and to reduce the necessary exchange foundations of spare parts in the operating parts.
