The historically grown regulations and organisational structures in aviation are a challenge for the intended digitalisation in the field of maintenance. In this context, manually performed scarf repairs are one of the hand operated workflows for which several projects have already been executed in relation to possible process automation. However, due to the very individual damage and component characteristics, this process will also require manual activities in the future. At present, there is no measurable quality assurance and assessment both afterwards and during the grinding process within scarf repairs. The technician works according to the manufacturers specifications, but he must be able to adapt his procedure for each case of damage and assess his work on the basis of his experience. For a better support of the technician during the scarfing process, an additional system component is propose, which also allows him to check his work in the form of visual feedback. In the context of the present work it is examined whether a visual assistance system is a suitable support for the technician and can ensure a usable evaluation regarding the quality of the scarf geometry. For this purpose, pilot tests are performed and analyzed on laboratory level as well as in cooperation with a maintenance company. Parallel to this, the process modification for the integration of the assistance system is demonstrated. Finally, possible application potentials in reference to current research activities for digital twins are discussed.
