Several researches have been made to determine the best system re-presentation for process diagnosis. Many approaches were considered, such asheuristic searches, event driven models, structural models... As of today, thereare no clear winners considering real applications on industrial systems.In this article, based on a specific system model, a diagnostic approach for com-plex systems is discussed. The proposed diagnostic algorithm processes a multi-layered system model and converges to the right representation granularity, suit-able to explain the fault and to identify the faulty subsystem or component. Themethod is adapted for a very specific application: the Avionics Test Bench (ATB)of the NH90, a medium weight multi-role military helicopter. The problem is re-formulated as a meta-diagnosis problem since the test bench may also host thefault. A detailed case study is presented for illustration.
