Abstract:

Probably the most difficult if not impossible item to evaluate in the spectromectric oil analysis programs within DOD is the consequence of things that have not happened. Although losses can be assessed when an undetected engine discrepancy results in an engine failure, losses cannot be assessed when such discrepancy has been detected and corrected by oil analysis before failure occurred. The objective of the task was to evaluate the consequence of not performing maintenance after an oil analysis laboratory predicted engine failure. During the program, 1376 samples were extracted from the C-141TF-33, 1929 samples from the KC-135J57-59, and 2458 samples from the B-52J57-43. The data shows that, although the spectrometric technique is capable of predicting incipient wear on oil-wetted parts prior to part failure, the decisions on the analysis results must be improved to achieve the most effective oil analysis programs.
