Zusammenfassung:	It is described a method of detecting an adjustment fault (47) related to a wind turbine rotor blade (1) mounted at a wind turbine rotor (4) and comprising an adaptable flow regulating device (11), in particular spoiler and/or flap, the method comprising: estimating a quantity (41) indicative of a change of a driving impact of wind (9) on the wind turbine rotor (4) based on at least two settings (19a, 19b) of the adaptable flow regulating device (11); determining another quantity (43) indicative of a desired change of the driving impact on the wind turbine rotor, in order to change a value (25) of a rotor speed to a reference value (27) of the rotor speed; and indicating an adjustment fault (47) based on a comparison of the quantity (41) with the other quantity (43).
