Analyser les risques en maintenance aéronautique, un projet complexe de conception.

In order to make helicopter maintenance safer, the Airbus Helicopters maintenance design office has undertaken to develop an approach to identify and assess the risk of maintenance errors. This communication seeks to understand how this approach is designed, how it is evolving and what are its uses within the Maintenance Engineering Department. We have identified that this approach is the result of a distributed design of a system of artefacts within many designers/users who do not all share the same objectives. We will investigate in what collective dynamic is the construction of this approach. [ABSTRACT FROM AUTHOR]
