Abstract:	An important problem in maintaining aging aircraft is the loss of strength due to environmental degradation. Laboratory tests involve subjecting test specimens to corrosive environments while under load for specified time periods and then testing the specimens for residual strength. Current ASTM standards specify using a uniform distribution to simulate a failure time for specimens that fail during the aging process. This paper investigates the use of a model for residual strength degradation that treats the premature failures as censored data.
