民用飞机预防性维修及 S4000P 标准剖析研究

Preventive maintenance is an indispensable part of civil aircraft operational support activities，and it is al⁃ so the basis for ensuring the safe and economic operation of civil aircraft. As the first international general standard for preventive maintenance，S4000P provides preventive maintenance with a reasonable analysis method for the for⁃ mulation of initial maintenance tasks throughout the life cycle，the analysis of unplanned maintenance tasks，and the optimization of initial maintenance tasks through operating data. In this paper the research status of preventive main⁃ tenance is combed，the S4000P standard is analyzed，and the analysis framework of civil aircraft preventive mainte⁃ nance is established based on S4000P，which provides strong support for promoting the formulation and optimiza⁃ tion process of civil aircraft preventive maintenance.
