• Abstract:
  This report describes three tasks related to probability of crack detection (POD) and aircraft systems reliablity. All three consider previous work in which crack growth simulations and crack detection data in the Service Difficulty Report (SDR) database were used to estimate the in-service POD. The first task compared the POD estimates with estimates obtained from other sources. The second task assessed the self-consistency of the estimate POD and the crack growth simulation. The third task integrated the POD estimates with crack growth data and residual strength models to assess the cumulative probability that damage will be detected as a function of loss in residual strength.
