Abstract: A process for scheduling engine inspection for a gas turbine engine includes computing an expected damage increment based on aircraft usage data of a single flight, computing a cumulative expected damage by summing the expected damage increment with a total set of historical expected damage increments since a previous maintenance, and determining an aggregate risk of failure based on the computed cumulative expected damage. A manual inspection is signaled when the aggregate risk of failure exceeds an acceptable risk threshold.
