1-1. PURPOSE. Volume III of the Joint Oil Analysis Program (JOAP) Manual presents the methodology for
evaluating spectrometric analyses of samples from aeronautical equipment. The methodology enables an
evaluator to identify wear metals present in the sample and their probable sources, to judge equipment condition,
and to make recommendations which influence maintenance and operational decisions. Following these
recommendations can enhance safety and equipment reliability and contribute to more effective and economic
maintenance practices.
