The objective of the investigation was to determine the feasibility of developing reliable accelerated life testing methods for aircraft hardware, based on currently documented failure case histories. Over 240 case histories involving more than 500 individual parts were categorized accord-ing to failure mode, elemental mechanical function, and corrective action employed. A THREE- DIMENSIONAL FAILURE-EXPERIENCE CELL MATRIX WAS DEVELOPED TO IMPLEMENT THE ORGANIZATION AND ANALYSIS OF THE DATA. Efforts to quantitatively evaluate corrective action effectiveness were frustrated by a lack of quantitative data, but a qualitative evaluation was accomplished.
