Abstract
The accurate assessment of aircraft structure damage risk is the premise
of establishing reasonable, economic and reliable maintenance intervals.
While many studies have proposed damage risk assessment methods for
aircraft structures, these methods lack the quantification of risk. This
paper proposed a risk assessment method of aircraft structure damage
maintenance interval considering fatigue crack growth rate and crack
detection rate. The damage process of aircraft structure was simulated
by Monte Carlo simulation to realize the quantitative assessment of
aircraft structure damage risk and maintenance interval. Taking an
aircraft fleet as an example, the damage risk of its wing structure was
simulated and analyzed. The results show that if the risk is controlled
within a reasonable range, the maintenance interval should be shortened
to 16 flight hours. At the same time, through the analysis of the risk
classification standard and the crack detection rate, the quantitative
evaluation of the risk classification standard was realized.
