An example method performed by a computing system for determining a maintenance interval for a subject aircraft configuration comprises obtaining sensor data reported by an electronic system of a population of the subject aircraft configuration. The method further comprises obtaining a failure mode definition that identifies a set of failure modes involving a component of the subject aircraft configuration. The method further comprises implementing a first predictive model to determine a first lifetime-probability distribution of a failure mode involving the component based on the sensor data. The method further comprises implementing a second predictive model that differs from the first predictive model to determine a second lifetime-probability distribution of a failure mode involving the component based on the sensor data. The method further comprises determining a maintenance interval for the component based on the first lifetime-probability distribution and the second lifetime-probability distribution.
