Condition Based Maintenance (CBM) is a prognostic and diagnostic maintenance strategy that monitors the actual condition of the asset to decide what maintenance needs to be done. CBM dictates that maintenance should only be performed when certain indicators show signs of decreasing performance or upcoming failure.
MERC continually seeks out software and hardware technologies for use with CBM. Successes include process improvements, such as automating the electronic capture of maintenance data at the point of service with the handheld Inspection Crack/Corrosion and Repair Reporting (ICARR 3D) system, Integrated Vehicle Health Monitoring (IVHMS) system and Loads/Environment Spectra Survey (L/ESS) System in coordination with the Aircraft Structural Integrity Program (ASIP).
MERC developed an algorithm method for rank-ordering the C-130 fleet in terms of anticipated maintenance needs, with a goal of basing depot schedules on aircraft condition rather than calendar scheduling.
MERC developed correlations between an aircraft’s condition as measured by age, flight hours, time since last depot, and usage, and the extent of maintenance required as measured by maintenance man-hours.
