End-to-End Credit Process Checklist System Level Baseline for Maintenance Credits -Specific aircraft Model with a defined certification basis -Maintenance Manual -CBM Airborne Data Acquisition and Monitoring System -CBM Ground Station -Operator‘s Maintenance Management System CBM Sensor and Flight Data Elements -Integrity of the source data (System of origination, qualification level, accuracy, resolution, validity checks) -Integrity of the sensor in aerospace environment (Performance Specification and Qualification as well as Calibration) -Verification and Validation of these elements are the same as any other hardware that is added to the aircraft and require no unique V&V process and should follow standard V&V processes that similar elements follow.
CBM Documentation Elements -Maintenance Credit Hazard Analysis -CBM user manual -CBM flight manual supplement -CBM Maintenance Manual Supplement -CBM Continuing Airworthiness Plan -Verification and Validation require no unique processes for this element CBM Airborne Monitoring System Elements -CI algorithms (Reference App D for Guidance) o Detection SNR/Resolution/Accuracy o Maintenance Limit (yellow) o Functional or Airworthiness Limit (red) -Application Software -Operating System Software -Data Acquisition Configuration File for aircraft physical configuration, sensor configuration, engineering units, data acquisition schedule, data acquisition conditions, and analyses applied -Airborne Processing Hardware (hardware qualified for environment) -HUMS systems DSC
