NAVAIR 17-15-50.3, JOINT OIL ANALYSIS PROGRAM MANUAL (VOLUME III): LABORATORY ANALYTICAL METHODOLOGY AND EQUIPMENT CRITERIA (AERONAUTICAL) (30-AUG-2013) [(ARMY) TM 38-301-3 (AIR FORCE) T.O. 33-1-37-3 (COAST GUARD) CGTO 33-1-37-3]., 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.
