Abstract: A technique is developed and demonstrated which can be used to estimate bus component failure distributions in an operational setting. The advantage of the described method is that it estimates the distribution of an entire population when only a portion of that population has experienced a failure (censored samples). Further, in an operational setting, components in a population do not age at the same rate and thus, their ages (in miles) are not ordered with respect to time. A sampling technique is derived to draw an ordered, censored sample from a population that has been aged in an operational setting. The resulting sample is used to estimate the life distribution of the component of interest.
