NAVAIR and the PF interval
This slide presentation provides some facts on the P-F interval. It concludes with a common misconception about the P-F graph.
Internal and external CBM variables
As maintenance or reliability engineers we need to discover what factors influence failure and failure probability. Which of those factors can we control, and which can we monitor for their predictive content. It will help to distinguish between External and … Continue reading
The elusive P-F interval
This article discusses the P-F Interval for CBM decision making, its areas of usefulness, and those areas where it is inadequate as a predictive maintenance strategy. An alternative more general approach based on the EXAKT system is proposed. Two categories … Continue reading
