Abstract�� The aircraft structural economic maintenance is one of the important aspects in the durability design of advanced aircraft.To assure economic life and reliability of aircraft structure,an economic maintenance program is essentially needed.In this paper,the effect of various factors on the determination of aircraft structural economic maintenance programme and the criteria of determining these factors are discussed in detail.From the practical engineering application point of view,an analytical methodology for the optimization of aircraft structural economic maintenance programme based on structure durability analysis is presented.It also accounts for the feature of evaluating the economic life of the repaired structures.A practical structural maintenance programme,as an example,to demonstrate the application of the methodology is given.
Keywords�� durability design   airplanes   structural reliability   optimization   economic maintenance
