At the present time vibration-based diagnostics methods are successfully being used to evaluate and predict the technical condition of onboard units and assemblies. They are the basis of health and usage monitoring systems installed on the helicopters. And these systems do not cover most of the details of helicopters and aircrafts. Therefore, it is necessary to develop new methods for covering all critical aviation units and assemblies which operate under complex structural load. These methods should be based on an objective evaluation of the technical state of structural materials which is used in the manufacture of products. It is important to get information on the controlled parameters of the structural material in the stage that corresponds to its predefective state. The development of these methods faces difficulties because of the fact that for measuring the parameters of the technical state of the structural material of aviation units and assemblies (structure, mechanical and structurally sensitive physical properties) requires to use special, as a rule, rather bulky equipment that can not be placed on board. Therefore, the authors propose an approach to select parameters that, on the one hand, have a very definite and unambiguous dependencies with the structure, mechanical and structurally sensitive physical properties of the structural material of aircraft assemblies and units. On the other hand, they can be monitored continuously during the aircraft operation.
