Description

Spectrometric analysis of used oil samples drawn from aircraft engine components is an integral part of the aircraft maintenance program in the United States Air Force. The samples are drawn at prescribed to monitor the levels of occurrence (in PPM) of certain wear metal contaminants. The observed contaminant levels as well as their rates of growth with time are used to assess the wear condition of an engine and to predict certain types of component failures before they can become critical. The interval between successive samples is called the sampling interval. The status of sampling intervals between oil analysis has been reviewed and a framework for an alternative approach to the determination of sampling intervals is discussed.
