Mission/Maintenance/Cycling Effects on Reliability

Abstract

This effort examined the effect of cycling and mission length on the mean-time-between failures (MTBF), cannot duplicate (CND), and induced failures. No correlation was found for CND or induced failures. For almost all of the equipment examined, the failure rate increased as the cycling rate increased. A composite curve was developed for six pieces of equipment on a single type of airframe having a range of missions of different lengths. The equation for the composite curve is given in the executive summary. Reliability, Cycling Effects, Mean-Time-Between-Failures (MTBF).
