In this paper we present a concept for acombination of wearable computing and knowledge management with the goal to shorten the maintenance process in the aircraft industry. This research is part of an ongoing project which is carried out in cooperation with the aircraft company Boeing. This paper describes the functions o the wearable devices as well as the conceptual realization. A wearable computer will support maintenance personnel by information on recent defects of the aircraft taken from an electronic logbook and a self-diagnosis-system. Manuals and part descriptions relative to the user's current focus of attention become accessible. Knowledge management will enable access to experience knowledge of colleagues and provide structural navigation. The core of the wearable computer is a PDA. The device can be used like a usual PDA in the handheld mode or it can be stored in a holder for wearable operation. In the holder, the PDA connects to an HMD and automatically adapts ist user interface to the changed modalities. By a wrist worn input device the user controls the wearable. The input device also contains a RFID scanner. The scanner will be used to identify areas in the aircraft. Subsequently the computer can display information and logbook entries associated to tha area. The aircraft itself will be equipped with RFID tags and a server to store the part descriptions with references to the RFIDtags. Data storage and knowledge management is not possible on the PDA directly. Thus, the PDA is designed as a client to a notebook computer carried in the toolbox of the technician.
