In every test final modal models have been determined out of several excitation runs according to meaningful quality measures. Obtained results from multiple free-free tests allow for conclusions concerning effects of the finishing and the repeatability of the manufacturing process in terms of the modal parameters. For this blade series the impact of the finish on mode shape correlation is stronger than differences resulting from the production. Regarding frequency and damping, changes caused by the finishing and deviations between the blades within the same manufacturing steps are of a similar magnitude. For blade #1 a non-linear damping behaviour in the 1 st flap mode has been identified. Though, a comprehensive flutter analysis demands in preparation the examination on non-linear behaviour in other modes of interest. Due to the high sensor density and the advantages of both test scenarios, the acquired modal **data** represents an optimal basis for updating finite element models towards structural dynamic properties.
