Designing for Maintainance-

All products, whether big or small need maintainance. It may be the replacement of an electric fuse, or servicing of an automobile or even the overhauling of an aircraft jet engine. Servicing of automobiles and aircrafts is basically preventive maintainance. Its purpose is to inspect the components, change the lubricants , tighten the nuts and bolts which may have loosened because of vibration in use, and correction of minor failures which, if not corrected, may lead to catastrophic failures.
