Based on the processing and analysis of flight experiment data, the law of distribution of the maximum load cycles of variable loads acting on typical chassis parts of domestic transport aircraft in various operating conditions was determined. The parameters of this law were determined for the most critical parts and the probability of occurrence of overload voltage cycles above a specified level during the operation of the aircraft was estimated.
 
Keywords: high-loaded parts, transport aircraft, reloading cycles, aircraft landing gear, the law of distribution of extreme values.
