Studies are often conducted to minimize the effect of vibration on equipment and its mechanisms. Since the engine is the main driving force of all technical objects, vibration is one of the factors hindering its operation. With this in mind, this article investigated the random probability distribution of vibration parameters using the laws of mathematical statistical distribution and was found to be compatible with the normal distribution law. At the same time, this study demonstrates that the proposed method of technical diagnostics can be used to assess helicopter engine failures.
