维修经济性是控制民机运营成本的关键因素。飞机计划维修具有明显的阶段性和周期性,从机龄角度飞机分为运营初期、成熟期和老龄期;按维修深度计划维修分为航线检查、A检、C检和D检。本文综合考虑机龄和计划维修之间的关系,构造了三层三等级的维修成本计算模型,并从维修的角度提出控制维修成本的措施。
Maintenance of economy is the key factor controlling the operating cost of civil aircraft. Aircraft maintenance plans have obvious phases and cyclical nature of the plane from the aircraft point of departure is divided into the initial operation, maturity and aging; maintenance maintenance by the maintenance plan is divided into route inspection, A inspection, C inspection and D inspection. In this paper, considering the relationship between machine age and planned maintenance, a three-level and three-level calculation model of maintenance cost is constructed, and measures to control maintenance costs are proposed from the perspective of maintenance.
