This research was undertaken in an aerospace company, which manufactures aero engines and also offers contracts, under which it remains responsible for the maintenance of engines. These contracts allow the company to collect far more data about the in-service performance of their engines than was previously available. This paper aims at understanding what parts of this in-service information are accessed when components or systems of existing aero engines need to be redesigned, because they have not performed as expected in service. In an attempt to address this aim, five case studies involving the redesign of components of an aero engine are examined. The redesign is based on the in-service experience of the existing components.The findings provide an understanding of the different types of information, and in particular the types of in-service information, accessed by designers in a redesign task.

Keywords: Information types, In-service information, Aerospace engineering, Knowledge management, Redesign, Document analysis.
