Research on Safety Analysis Method Based on Civil Aircraft Maintenance Operation

At present, during the overall design of civil aircraft in China, although the aircraft system safety analysis activities have become more and more perfect, the failure to systematically considering the safety of the aircraft maintenance operation process may still lead to a large number of aircraft accidents caused by maintenance errors. This paper studies a complete set of evaluation methods for the safety of civil aircraft maintenance operations, including the evaluation process and specific implementation tools, and introduces in detail the maintenance operation steps, hazard identification, risk level evaluation, and improvement measures as well as methods and tools related to evaluation of process control. The application of this method is proved to be reasonable and effective, which can greatly save the development cycle and cost.
