MERC developed correlations between a C-130 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. Process improvements, such as automating the electronic capture of maintenance data at the point of service are a vital part of effective condition based maintenance. The CBM index is determined from the aircraft's age, flight hours, time since last depot, and usage. Data analysis shows that the CBM index is strongly correlated to the maintenance requirements.Condition Based MaintenanceCondition Based MaintenanceCondition Based Maintenance
