Reliability Prognosis to Improve Aircraft Maintenance

Maintenance is evolving towards a new predictive process that increases efficiency (availability, reliability and safety), minimizes economic costs and helps to assess risks and to make decisions. In the aeronautical industry, especially, this new maintenance has to be very precise to reduce delays and cancellations in operational plans, while maximizing minimal loss of safety. This presentation shows an approach, based on ageing modeling, to enhance the prognosis in the case of electronic component failure prediction and operational reliability and usage based maintenance planning.
