Belvoir, VA 22060-5565) D.2.3 Process Description CBM is a maintenance approach that uses the status and condition of the asset to determine its maintenance needs. CBM is dependent on the collection of data from sensors and the processing, analysis and correlation of that data to maintenance actions.
The processes governing CI and HI development are: a. Physics of Failure Analysis b. Detection Algorithm Development c. Fault Correlation Data Mining d. Fault Validation/Seeded Fault Analysis e. Inspection/Tear Down Analysis f. Electronic and Embedded Diagnostics (BIT)/(BITE) The technical processes described above are used to create a comprehensive and integrated knowledge base which develops effective maintenance tasks and supporting processes necessary to sustain normal operations.
The knowledge base changes during the life cycle of the aircraft and serves as the foundation for changes to maintenance practice created by new failure modes, aging effects, and changes to the mission profiles of the aircraft. In addition, as new technology, such as corrosion sensors or improved diagnostics for avionics, becomes proven, new data and detection algorithms will be added to the knowledge base. D.3 PROCESS GUIDANCE Detailed FMECA, often completed as a part of RCM analysis, is a favorable starting point for understanding the system, subsystem, or component for which the CIs are being developed.
