Abstract : This report summarizes an investigation into the feasibility of monitoring hydraulic system wear debris characteristics in order to predict failures. The investigation utilized hydraulic pumps from an RA-5C aircraft hydraulic system and was monitored by spectrometric analysis and ferrography. Based on one relevant failure it was determined that ferrography can predict a failure of a pump prior to its occurence. Spectrometric results were not useful in the prediction. (Author)
