Time maintenance State maintenance Fatigue damage Flight data recorder
If aviation maintenance wants to change from the current reactive,fault-based maintenance to state-based maintenance program transformation,we need to reduce or even abolish schedule maintenance tasks based on the fatigue life assumptions or standardized timing overhaul.First of all,in this paper,the loading spectrums of center of helicopter gravity were obtained by analysis of the data of flight data recorder.Then,the nominal stress method based on the data of flight data recorder was developed and the opposite fatigue damage of every helicopter in some air fleet was computed.The results accorded well with fact.Lastly,the reliability of the life by computing opposite fatigue damage was analyzed.Analysis results showed that the management of helicopter structure life was a dynamic process and the main idea of conversion from time maintenance to state maintenance was rational and feasible.
