Conditioned-Based Maintenance at USC - Part III: Aircraft Components Mapping and Testing for CBM

One of the most expensive and time consuming tasks relating to Condition Based Maintenance involves the testing of mechanical components for CBM. A scientific plan is being developed to identify components that will return the most value within a short time for implementation of CBM. This plan is also based on the historical (TAMMS-A and VMU) data that we have collected and analyzed throughout the past eight years. This paper specifically addresses the component mapping methodologies and the USC CBM test facilities. Furthermore, the CBM testing approach is discussed. The goal of testing is to identify the root causes of components' failure, failure modes and the identification of ways to improve serviceability of A/C components. Components testing will be carried out for used but serviceable components or with components with intentionally seeded faults. Some component test results are presented and discussed.
