An inspection system adapted to perform retro positive material identification of components of a multi-feature system. The inspection system comprises an electronic drawing, a positive material identification database, a field load sheet and a data logger. The electronic drawing has tagged locations identifying respective features of the multi-feature system to be read for retro positive material identification analysis. The electronic drawing has at least one unique identification code for each tagged location. The positive material identification database has component information records for respective components. Each component information record correlated to a component associated with one tagged location of the electronic drawing. The field load sheet has identification codes for respective tagged locations. The identification codes of the field load sheet are correlated to the component information records of the positive material identification database. The data logger receives identification codes for respective tagged locations from the field load sheet, and also collects material composition analysis data. The data logger communicates the identification codes and the collected material composition analysis data to the positive material identification database for populating the component information records of the positive material identification database with the material composition analysis data.
