舰载机维修保障系统间相关因素较多，维修复杂程度较高。提高舰载机的维修保障效能，尤其是改进维修体制、维修方式，已成为军事装备领域研究的热点问题之一。合理构建舰载机的维修体制，是提高舰载机战备完好性、降低其寿命周期费用的有效途径。对比了国内外军机维修在三级维修体制与两级维修体制下的运行方式，分析了三级维修的弊端；借鉴国外军用飞机的维修理念，针对中国舰载机维修保障的特点和存在问题，探讨了舰载机实行两级维修的运行模式及相关的关键环节。

The maintenance support system of the carrier-based aircraft involves a high complexity of maintenance work. It is important to enhance the support effectiveness for the carrier-based aircraft, especially, to improve the maintenance system and the maintenance methods. To meet the requirements of the future integration joint combat, improve the combat readiness integrity and enhance the operational capability, the formulation of the carrier-based aircraft maintenance must keep pace with the time. It is an effective way to increase the level of operational readiness and reduce life-cycle costs by constructing a reasonable carrier-based aircraft maintenance system. The operation modes of the carrier-based aircraft under the three-level maintenance system and the two-level maintenance system at home and abroad are compared, the disadvantages of the three-level maintenance system are analyzed,and the foreign advanced concepts of the military aircraft maintenance are considered. With some issues in the carrier-based aircraft maintenance support system in mind, the mode of the carrier-based aircraft two-level maintenance and the key aspects related to the system are discussed.
