Abstract
Maintenance interventions are planned using RUL (Remaining Useful Life) estimations obtained from a PHM (Prognostics and Health Monitoring) system as well as estimations of spare parts availability. PHM information is used to verify whether spare parts will be available when the next failures are expected to occur, and expected RUL of a component or system based on a set of measurements collected from the aircraft systems can be used to schedule repair times that do not conflict with other repairs to avoid wait time and maximize repair shop capacity utilization.
