The urgency of the research questions and identifying risk monitoring of the technical state of the aviation system. An new approach to the assessment of risks and vulnerabilities of the object. Considered a probabilistic approach to the assessment of the residual resource, taking into account the identified defects. Proposed equivalents losses in assessing the risks of direct or indirect consequences of faulty technical condition of aircraft. It was determined that the problem of the risk assessment, finding defects and damages, as well as the prediction of residual life of the instrument according to monitoring in the mathematical sense, belong to the category of inverse problems, the best way to solve them is the method of reconstruction using Bayesian a priori information.
