6. Between Law and Safety : Licensed Aircraft Maintenance Engineers and the Socio-professional Construction of Legality in European Civil Aviation
Abstract : The survey and interview-based mixed methods research presented in this compilation dissertation explores how licensed aircraft maintenance engineers in Sweden, Norway and Portugal experience working under the vertical chain of hard and soft law that makes up the European Union regulation of this sector. By focusing on occurrence reporting and the certification and release of aircraft into service, as two regulated phenomena directly shaping the everyday working lives of these maintenance engineers, the research ultimately found that a sectorial legal consciousness emerged that is characterised by normative pluralism and a shared professional cultural allegiance to a norm of putting safety first.

7. Mathematical Modeling, Optimization and Scheduling of Aircraft's Components Maintenance and of the Maintenance Workshop
Abstract : This research concerns the simultaneous scheduling of preventive maintenance for a fleet of aircraft and their common components along with the maintenance workshop, to which the components are sent for repair. The problem arises from an industrial project with the Swedish aerospace and defence company Saab. READ MORE

9. Improved remaining useful life estimations for on-condition parts in aircraft engines
Abstract : This thesis focuses on obtaining better estimates of remaining life for on-condition (OC) parts in aircraft engines. Aircraft engine components are commonly classified into three categories, life-limited parts (LLP), OC-parts and consumables. Engine maintenance typi-cally accounts for 10% to 20% of aircraft-related operating cost. READ MORE

10. An assessment of operational consequences of failures to support aircraft scheduled maintenance program development
Abstract : A majority of the direct and indirect maintenance costs in the life cycle of aircraft stems from the consequences of decisions taken during the initial maintenance program development. In particular, the preventive and corrective maintenance requirements, which greatly influence both the system availability and life cycle cost, need to be defined in order to perform only those preventive actions that are absolutely necessary and costeffective.
