As the economic level rising, the function and stability of civil aircraft have been greatly improved. However, with the development of science and technology in modern civil aviation transportation, the frequent occurrence of flight accidents has threatened people’s safety. The main reason is the internal failure of the engine body or the daily maintenance management is incomplete. Therefore, the relevant maintenance management departments should attach great importance to the first core research and management of civil aircraft stability and safety. In view of various equipment problems existing in the operation of civil aircraft, the practical application of data collection mode and maintenance information disclosure mode of modern aircraft maintenance equipment is analyzed. This paper describes some characteristics of aircraft maintenance work, and combined with the main factors affecting the risk of civil aircraft maintenance, giving countermeasures and suggestions to effectively improve the level of civil aircraft maintenance risk management.
