A method, apparatus, system, and computer program product for managing a platform. Sensor information for a platform health of the platform is received from a sensor system for the platform. The sensor information for the platform health of the platform is sent by a computer system into a machine learning model trained using historical sensor information indicating a historical platform health and historical context information corresponding to the historical sensor information in which the historical context information is for a set of operating conditions. A remaining useful life of a component in the platform is received by the computer system from the machine learning model.

Aircraft maintenance of line replaceable units

A method, apparatus, system, and computer program product for managing a platform. A computer system generates a training dataset comprising historical metric values from historical sensor information for a set of metrics for a part and historical maintenance events for the part. The computer system trains a machine learning model using the training dataset. The computer system determines different maintenance thresholds for maintenance parameters for a metric in the set of metrics for performing maintenance on the part using the machine learning model trained with the training dataset. The computer system selects maintenance thresholds for the maintenance parameters from the maintenance thresholds meeting an objective to form a maintenance plan. The maintenance plan is used to determine when a maintenance action is needed for the part.

Vehicle health management using a counterfactual machine learning model to optimize maintenance parameters

A method and apparatus for non-destructively measuring the depth of a crack with precision and accuracy in a workpiece using an eddy current process. The method involves empirically creating a response curve of the eddy current response produced from crack(s) in a sample workpiece(s), wherein the depth of the crack(s) in the sample workpiece(s) may be modified a plurality of times and an eddy current response reading is taken at each different crack depth. The response curve is then used to interpolate the depth of a crack in a workpiece composed of the same material non-destructively by measuring the eddy current response in the workpiece crack and then obtaining the predetermined crack depth value form the response curve.
