  One of the most appreciated features of Fault Trees (FTs) is their
simplicity, making them fit into industrial processes. As such processes evolve
in time, considering new aspects of large modern systems, modelling techniques
based on FTs have adapted to these needs. This paper proposes an extension of
FTs to take into account the problem of Predictive Maintenance, one of the
challenges of the modern dependability field of study. The paper sketches the
Predictive Fault Tree language and proposes some use cases to support their
modelling and analysis in concrete industrial settings.
