This report describes a thesis project in aeronautical engineering carried out during April and May 2011 at ST Aerospace Solutions, Arlanda. The company is one of Europe’s leading aviation component maintenance companies.

The task for this thesis project has been to develop a baseline overhaul work package for the thrust reverser system of the Rolls-Royce Trent 700 jet engine.

An overhaul work package is a collection of maintenance work sheets (MWS) used by the maintenance organization to confirm that a specific maintenance procedure has been carried out correctly. Documenting the maintenance work performed on a component is required in order to comply with the regulations of the European Aviation Safety Agency (EASA).

To be able to solve the task, the authors had to study maintenance manuals, learn the functions of the thrust reverser and get an overview of how the maintenance organization works. Much of the work has been conducted in consultation with the company’s engineering department.

The result is an overhaul package consisting of approximately 40 MWS’s. These have been designed to promote traceability of actions and to be easily revisable.
