Nonoperating Failure Rates for Avionics Study.

Abstract

This report presents the results of a study of the nonoperating failure rates of USAF avionic equipments. Quantitative assessment data on 26 different equipment/aircraft applications are included. The nonoperating failure rates as determined by three different methods utilizing Air Force maintenance data were measurably significant. On average, MTBF assessment results are improved by 22% when nonoperating failures are excluded from operational MTBF assessments. Average operating to nonoperating failure rate ratios for the equipments investigated ranged from 41 to 188. Comparisons between several reliability prediction methods and operational reliability levels achieved are included. Based on the six equipment types analyzed, it is concluded that field nonoperating failure rates cannot be predicted to a reasonable degree of accuracy by using any of the established prediction methods.
